| 1 | Carbon foam with microporous structure for high performance symmetric potassium dual-ion capacitor显示文摘A novel carbon foam with microporous structure(CFMS),with the advantages of a simple fabrication process,low energy consumption,large specific surface area and high conductivity,has been prepared by a facile one-step carbonization.In addition,the carbon foam possesses suitable interlayer spacing in short range which is flexible to accommodate the deformation of carbon layer caused by the ion insertion and deinsertion at the charge and discharge state.Furthermore,a low cost carbon-based symmetric potassium dual-ion capacitor(PDIC),which integrates the virtues of potassium ion capacitors and dual-ion batteries,is successfully established with CFMS as both the battery-type cathode and the capacitor-type anode.PDIC displays a superior rate performance,an ultra-long cycle life(90%retention after 10000 cycles),and a high power density of 7800 W kg^-1 at an energy density of 39Whkg^-1.The PDIC also exhibits excellent ultrafast charge and slow discharge properties,with a full charge in just 60 s and a discharge time of more than 3000 s. | Yanhong Feng Suhua Chen Jue Wang Bingan Lu | 2020 | Journal of Energy Chemistry2020,29,4: | 10 |
| 2 | Interfacial adsorption-insertion mechanism induced by phase boundary toward better aqueous Zn-ion battery显示文摘Biphasic and multiphasic compounds have been well clarified to achieve extraordinary electrochemical properties as advanced energy storage materials.Yet the role of phase boundaries in improving the performance is remained to be illustrated.Herein,we reported the biphasic vanadate,that is,Na_(1.2)V_(3)O_(8)/K_(2)V_(6)O_(16)·1.5H_(2)O(designated as Na0.5K0.5VO),and detected the novel interfacial adsorption-insertion mechanism induced by phase boundaries.Firstprinciples calculations indicated that large amount of Zn^(2+)and H^(+)ions would be absorbed by the phase boundaries and most of them would insert into the host structure,which not only promote the specific capacity,but also effectively reduce diffusion energy barrier toward faster reaction kinetics.Driven by this advanced interfacial adsorption-insertion mechanism,the aqueous Zn/Na_(0.5)K_(0.5)VO is able to perform excellent rate capability as well as long-term cycling performance.A stable capacity of 267 mA h g^(-1)after 800 cycles at 5 A g^(-1)can be achieved.The discovery of this mechanism is beneficial to understand the performance enhancement mechanism of biphasic and multiphasic compounds as well as pave pathway for the strategic design of highperformance energy storage materials. | Lutong Shan Yiren Wang Shuquan Liang Boya Tang Yongqiang Yang Ziqing Wang Bingan Lu Jiang Zhou | 2021 | InfoMat2021,3,9: | 8 |

| 4 | Inorganic Colloidal Electrolyte for Highly Robust Zinc‑Ion Batteries显示文摘Zinc-ion batteries(ZIBs)is a promising electrical energy storage candidate due to its eco-friendliness,low cost,and intrinsic safety,but on the cathode the element dissolution and the formation of irreversible products,and on the anode the growth of dendrite as well as irreversible products hinder its practical application.Herein,we propose a new type of the inorganic highly concentrated colloidal electrolytes(HCCE)for ZIBs promoting simultaneous robust protection of both cathode/anode leading to an effective suppression of element dissolution,dendrite,and irreversible products growth.The new HCCE has high Zn^(2+)ion transference number(0.64)endowed by the limitation of SO4^(2−),the competitive ion conductivity(1.1×10^(–2) S cm^(−1))and Zn2+ion diffusion enabled by the uniform pore distribution(3.6 nm)and the limited free water.The Zn/HCCE/α-MnO2 cells exhibit high durability under both high and low current densities,which is almost 100%capacity retention at 200 mA g^(−1) after 400 cycles(290 mAh g^(−1))and 89%capacity retention under 500 mA g^(−1) after 1000 cycles(212 mAh g^(−1)).Considering material sustainability and batteries’high performances,the colloidal electrolyte may provide a feasible substitute beyond the liquid and all-solid-state electrolyte of ZIBs. | Jiawei Gao Xuesong Xie Shuquan Liang Bingan Lu Jiang Zhou | 2021 | Nano-Micro Letters2021,13,4: | 6 |
| 5 | Metal-Organic Frameworks Functionalized Separators for Robust Aqueous Zinc-Ion Batteries显示文摘Aqueous zinc-ion batteries(AZIBs)are one of the promising energy storage systems,which consist of electrode materials,electrolyte,and separator.The first two have been significantly received ample development,while the prominent role of the separators in manipulating the stability of the electrode has not attracted sufficient attention.In this work,a separator(UiO-66-GF)modified by Zr-based metal organic framework for robust AZIBs is proposed.UiO-66-GF effectively enhances the transport ability of charge carriers and demonstrates preferential orientation of(002)crystal plane,which is favorable for corrosion resistance and dendrite-free zinc deposition.Consequently,Zn|UiO-66-GF-2.2|Zn cells exhibit highly reversible plating/stripping behavior with long cycle life over 1650 h at 2.0 mA cm^(−2),and Zn|UiO-66-GF-2.2|MnO_(2) cells show excellent long-term stability with capacity retention of 85%after 1000 cycles.The reasonable design and application of multifunctional metal organic frameworks modified separators provide useful guidance for constructing durable AZIBs. | Yang Song Pengchao Ruan Caiwang Mao Yuxin Chang Ling Wang Lei Dai Peng Zhou Bingan Lu Jiang Zhou Zhangxing He | 2022 | Nano-Micro Letters2022,14,12: | 5 |
| 6 | Highly Dispersed Cobalt Nanoparticles Embedded in Nitrogen-Doped Graphitized Carbon for Fast and Durable Potassium Storage显示文摘Potassium-ion batteries(KIBs)have great potential for applications in large-scale energy storage devices.However,the larger radius of K+leads to sluggish kinetics and inferior cycling performance,severely restricting its practical applicability.Herein,we propose a rational strategy involving a Prussian blue analogue-derived graphitized carbon anode with fast and durable potassium storage capability,which is constructed by encapsulating cobalt nanoparticles in nitrogen-doped graphitized carbon(Co-NC).Both experimental and theoretical results show that N-doping effectively promotes the uniform dispersion of cobalt nanoparticles in the carbon matrix through Co-N bonds.Moreover,the cobalt nanoparticles and strong Co-N bonds synergistically form a threedimensional conductive network,increase the number of adsorption sites,and reduce the diffusion energy barrier,thereby facilitating the adsorption and the diffusion kinetics.These multiple effects lead to enhanced reversible capacities of 305 and 208.6 mAh g^−1 after 100 and 300 cycles at 0.05 and 0.1 A g^−1,respectively,demonstrating the applicability of the Co-NC anode for KIBs. | Xiaodong Shi Zhenming Xu Cheng Han Runze Shi Xianwen Wu Bingan Lu Jiang Zhou Shuquan Liang | 2021 | Nano-Micro Letters2021,13,2: | 4 |
| 7 | Large-scale carambola-like V_(2)O_(5) nanoflowers arrays on microporous reed carbon as improved electrochemical performances lithium-ion batteries cathode显示文摘To search for new cathode materials with high energy density of Lithium-ion batteries(LIBs) is one of the most challenging issues. Vanadium pentoxide(V2 O5) with high theoretical specific capacity is believed to be a promising candidate for the next generation cathode materials, yet still suffers from low lithium ion diffusion coefficient and poor electronic conductivity resulting in low cycling life and poor rate performances. Here, we report new large-scale carambola-like V2 O5 nanoflowers arrays anchored on microporous reed carbon as high performances LIBs cathode. Each individual pore space of the microporous reed carbon is like a hexagonal cylinder, and the area of each carbon wall is more than103 um2, which is favorable for the growth of V2 O5 nanostructure arrays. After hydrothermal, the largescale carambola-like V2 O5 nanoflowers arrays can directly grow on the surface of microporous carbon.Due to the novel composite structures, the V2 O5 nanoflowers arrays@microporous carbon stabilizes at273 mA h g^(-1) after 100 cycles at 0.2 C. When cycling at 1.0 C over 500 cycles, the capacity still maintains at 180 mAh g^(-1). The demonstrated approach in this work paves the way for the development of high rate capability and excellent cycling stability V2 O5-based cathode materials. | Hua Tan Xin Zhi Yu Kai Huang Jianxin Zhong Bingan Lu | 2020 | Journal of Energy Chemistry2020,29,12: | 4 |

| 9 | A Silicon Monoxide Lithium-Ion Battery Anode with Ultrahigh Areal Capacity显示文摘Silicon monoxide(SiO)is an attractive anode material for next-generation lithium-ion batteries for its ultra-high theoretical capacity of 2680 mAh g−1.The studies to date have been limited to electrodes with a rela-tively low mass loading(<3.5 mg cm^(−2)),which has seriously restricted the areal capacity and its potential in practical devices.Maximizing areal capacity with such high-capacity materials is critical for capitalizing their potential in practi-cal technologies.Herein,we report a monolithic three-dimensional(3D)large-sheet holey gra-phene framework/SiO(LHGF/SiO)composite for high-mass-loading electrode.By specifically using large-sheet holey graphene building blocks,we construct LHGF with super-elasticity and exceptional mechanical robustness,which is essential for accommodating the large volume change of SiO and ensuring the structure integrity even at ultrahigh mass loading.Additionally,the 3D porous graphene network structure in LHGF ensures excellent electron and ion transport.By systematically tailoring microstructure design,we show the LHGF/SiO anode with a mass loading of 44 mg cm^(−2)delivers a high areal capacity of 35.4 mAh cm^(−2)at a current of 8.8 mA cm^(−2)and retains a capacity of 10.6 mAh cm^(−2)at 17.6 mA cm^(−2),greatly exceeding those of the state-of-the-art commercial or research devices.Furthermore,we show an LHGF/SiO anode with an ultra-high mass loading of 94 mg cm^(−2)delivers an unprecedented areal capacity up to 140.8 mAh cm^(−2).The achievement of such high areal capacities marks a critical step toward realizing the full potential of high-capacity alloy-type electrode materials in practical lithium-ion batteries. | Jiang Zhong Tao Wang Lei Wang Lele Peng Shubin Fu Meng Zhang Jinhui Cao Xiang Xu Junfei Liang Huilong Fei Xidong Duan Bingan Lu Yiliu Wang Jian Zhu Xiangfeng Duan | 2022 | Nano-Micro Letters2022,14,3: | 4 |
| 10 | Interfacial Engineering Strategy for High-Performance Zn Metal Anodes显示文摘Due to their high safety and low cost,rechargeable aqueous Zn-ion batteries(RAZIBs)have been receiving increased attention and are expected to be the next generation of energy storage systems.However,metal Zn anodes exhibit a limited-service life and inferior reversibility owing to the issues of Zn dendrites and side reactions,which severely hinder the further development of RAZIBs.Researchers have attempted to design high-performance Zn anodes by interfacial engineering,including surface modification and the addition of electrolyte additives,to stabilize Zn anodes.The purpose is to achieve uniform Zn nucleation and flat Zn deposition by regulating the deposition behavior of Zn ions,which effectively improves the cycling stability of the Zn anode.This review comprehensively summarizes the reaction mechanisms of interfacial modification for inhibiting the growth of Zn dendrites and the occurrence of side reactions.In addition,the research progress of interfacial engineering strategies for RAZIBs is summarized and classified.Finally,prospects and suggestions are provided for the design of highly reversible Zn anodes. | Bin Li Xiaotan Zhang Tingting Wang Zhangxing He Bingan Lu Shuquan Liang Jiang Zhou | 2022 | Nano-Micro Letters2022,14,1: | 3 |
| 11 | Biocompatible zinc battery with programmable electro-cross-linked electrolyte显示文摘Aqueous zinc batteries(ZBs) attract increasing attention for potential applications in modern wearable and implantable devices due to their safety and stability.However,challenges associated with biosafety designs and the intrinsic electrochemistry of ZBs emerge when moving to practice,especially for biomedical devices.Here,we propose a green and programmable electro-cross-linking strategy to in situ prepare a multi-layer hierarchical Zn-alginate polymer electrolyte(Zn-Alg) via the superionic binds between the carboxylate groups and Zn^(2+).Consequently,the Zn-Alg electrolyte provides high reversibility of 99.6 5 %Coulombic efficiency(CE),>500 h of long-time stability and high bio compatibility(no damage to gastric and duodenal mucosa) in the body.A wire-shaped Zn/Zn-Alg/α-MnO_(2) full battery affords 95% capacity retention after 100 cycles at 1 A g^(-1) and good flexibility.The new strategy has three prominent advantages over the conventional methods:(ⅰ) the cross-linking process for the synthesis of electrolytes avoids the introduction of any chemical reagents or initiators;(ⅱ) a highly reversible Zn battery is easily provided from a micrometer to large scales through automatic programmable functions;and(ⅲ) high biocompatibility is capable of implanted and bio-integrated devices to ensure body safety. | Xuesong Xie Jingjing Li Zhengyue Xing Bingan Lu Shuquan Liang Jiang Zhou | 2023 | National Science Review2023,10,3: | 2 |
| 12 | Yolk-Shell P3-Type K_(0.5)[Mn_(0.85)Ni_(0.1)Co_(0.05)]O_(2):A Low-Cost Cathode for Potassium-Ion Batteries显示文摘Low-cost preparation methods for cathodes with high capacity and long cycle life are crucial for commercializing potassium-ion batteries(PIBs).Presently,the charging/discharging strain that develops in the active cathode material of PIBs causes cracks in the particles,leading to a sharp capacity fade.Here,to abate the strain release and the need for an industrially relevant process,a simple low-cost co-precipitation method for synthesizing yolk-shell P3-type K_(0.5)[Mn_(0.85)Ni_(0.1)Co_(0.05)]O_(2) (YS-KMNC)was reported.As cathode material for PIBs,the YS-KMNC delivers a high reversible capacity(96 mAh g^(-1) at 20 mA g^(-1))and excellent cycle stability(80.5%retention over 400 cycles at a high current density of 200 mA g^(-1)).More importantly,a full battery assembled with the YS-KMNC cathode and a commercial graphite anode exhibits a high operating voltage(0.5-3.4 V)and an excellent cycling performance(84.2%retention for 100 cycles at 100 mA g^(-1)).Considering the low-cost,simple production process and high performance of YS-KMNC cathode,this work could pave the way for the commercial development of PIBs. | Jiaxin Hao Ke Xiong Jiang Zhou Apparao M.Rao Xianyou Wang Huan Liu Bingan Lu | 2022 | Energy & Environmental Materials2022,5,1: | 2 |
| 13 | A functionalized separator enables dendrite-free Zn anode via metal-polydopamine coordination chemistry显示文摘Designing a multifunctional separator with abundant ion migration paths is crucial for tuning the ion transport in rocking-chair-type batteries.Herein,a polydopamine-functionalized PVDF(PVDF@PDA)nanofibrous membrane is designed to serve as a separator for aqueous zinc-ion batteries(AZIBs).The functional groups(OH and NH)in PDA facilitate the formation of Zn O and Zn N coordination bonds with Zn ions,homogenizing the Zn-ion flux and thus enabling dendrite-free Zn deposition.Moreover,the PVDF@PDA separator effectively inhibits the shuttling of V-species through the formation of V-O coordination bonds.As a result,the Zn/NH_(4)V_(4)O_(10) battery with the PVDF@PDA separator exhibits enhanced cycling stability(92.3%after 1000 cycles at 5 A g^(-1))and rate capability compared to that using a glass fiber separator.This work provides a new avenue to design functionalized separators for high-performance AZIBs. | Yanfen Liu Shude Liu Xuesong Xie Zhicheng Li Pinji Wang Bingan Lu Shuquan Liang Yan Tang Jiang Zhou | 2023 | InfoMat2023,5,3: | 2 |
| 14 | Cell-like-carbon-micro-spheres for robust potassium anode显示文摘Large-scale low-cost synthesis methods for potassium ion battery(PIB)anodes with long cycle life and high capacity have remained challenging.Here,inspired by the structure of a biological cell,biomimetic carbon cells(BCCs)were synthesized and used as PIB anodes.The protruding carbon nanotubes across the BCC wall mimicked the ion-transporting channels present in the cell membrane,and enhanced the rate performance of PIBs.In addition,the robust carbon shell of the BCC could protect its overall structure,and the open space inside the BCC could accommodate the volume changes caused by K+insertion,which greatly improved the stability of PIBs.For the first time,a stable solid electrolyte interphase layer is formed on the surface of amorphous carbon.Collectively,the unique structural characteristics of the BCCs resulted in PIBs that showed a high reversible capacity(302 m Ah g^(-1)at 100 m A g^(-1)and 248 mAh g^(-1)at500 m A g^(-1)),excellent cycle stability(reversible capacity of 226 m Ah g^(-1)after 2100 cycles and a continuous running time of more than 15 months at a current density of 100 m A g^(-1)),and an excellent rate performance(160 mAh g^(-1)at 1 A g^(-1)).This study represents a new strategy for boosting battery performance,and could pave the way for the next generation of battery-powered applications. | Hongbo Ding Jiang Zhou Apparao M.Rao Bingan Lu | 2021 | National Science Review2021,8,9: | 2 |
| 15 | Tuning crystal structure and redox potential of NASICON-type cathodes for sodium-ion batteries显示文摘Sodium superionic conductor(NASICON)-type compounds have been regarded as promising cathodes for sodium-ion batteries(SIBs)due to their favorable ionic conductivity and robust structural stability.However,their high cost and relatively low energy density restrict their further practical application,which can be tailored by widening the operating voltages with earth-abundant elements such as Mn.Here,we propose a rational strategy of infusing Mn element in NASICON frameworks with sufficiently mobile sodium ions that enhances the redox voltage and ionic migration activity.The optimized structure of Na3.5Mn0.5V1.5(PO4)3/C is achieved and investigated systematically to be a durable cathode(76.6%capacity retention over 5,000 cycles at 20 C)for SIBs,which exhibits high reversible capacity(113.1 mAh·g^−1 at 0.5 C)with relatively low volume change(7.6%).Importantly,its high-areal-loading and temperature-resistant sodium ion storage properties are evaluated,and the full-cell configuration is demonstrated.This work indicates that this Na3.5Mn0.5V1.5(PO4)3/C composite could be a promising cathode candidate for SIBs. | Xuemei Ma Xinxin Cao Yifan Zhou Shan Guo Xiaodong Shi Guozhao Fang Anqiang Pan Bingan Lu Jiang Zhou Shuquan Liang | 2020 | Nano Research2020,13,12: | 2 |
| 16 | Cocoon Silk-Derived, Hierarchically Porous Carbon as Anode for Highly Robust Potassium-Ion Hybrid Capacitors显示文摘Potassium-ion hybrid capacitors(KIHCs) have attracted increasing research interest because of the virtues of potassium-ion batteries and supercapacitors.The development of KIHCs is subject to the investigation of applicable K+storage materials which are able to accommodate the relatively large size and high activity of potassium.Here,we report a cocoon silk chemistry strategy to synthesize a hierarchically porous nitrogen-doped carbon(SHPNC).The as-prepared SHPNC with high surface area and rich N-doping not only offers highly efficient channels for the fast transport of electrons and K ions during cycling,but also provides sufficient void space to relieve volume expansion of electrode and improves its stability.Therefore,KIHCs with SHPNC anode and activated carbon cathode afford high energy of 135 Wh kg-1(calculated based on the total mass of anode and cathode),long lifespan,and ultrafast charge/slow discharge performance.This study defines that the KIHCs show great application prospect in the field of high-performance energy storage devices. | Haiyan Luo Maoxin Chen Jinhui Cao Meng Zhang Shan Tan Lei Wang Jiang Zhong Hongli Deng Jian Zhu Bingan Lu | 2020 | Nano-Micro Letters2020,12,9: | 2 |
| 17 | An all-organic aqueous potassium dual-ion battery显示文摘Benefiting from the environmental friendliness of organic electrodes and the high security of aqueous electrolyte,an all-organic aqueous potassium dual-ion full battery(APDIB) was assembled with 21 M potassium bis(fluoroslufonyl)imide(KFSI) water-in-salt as the electrolyte.The APDIB could deliver a reversible capacity of around 50 mAh g^(-1) at 200 mA g^(-1)(based on the weight of total active materials),a long cycle stability over 900 cycles at 500 mA g^(-1) and a high coulombic efficiency of 98.5%.The reaction mechanism of APDIB during the charge/discharge processes is verified:the FSI-could associate/disassociate with the nitrogen atom in the polytriphenylamine(PTPAn) cathode,while the K^(+) could react with C=O bonds in the 3,4,9,10-perylenetetracarboxylic diimide(PTCDI) anode reversibly.Our work contributes toward the understanding the nature of water-into-salt electrolyte and successfully constructed all-organic APDIB. | Junmin Ge Xianhui Yi Ling Fan Bingan Lu | 2021 | Journal of Energy Chemistry2021,30,6: | 2 |
| 18 | N/S co-doped carbon nanosheet bundles as high-capacity anode for potassium-ion battery显示文摘Potassium-ion batteries(PIBs)are of academic and economic significance,but still limited by the lack of highly active electrode materials for de-/intercalation of large-radius K ions.Herein,an interconnected nitrogen/sulfur co-doped carbon nanosheep bundle(N/S-CSB)was proposed as the potassium ions storage material.The rich co-doping of nitrogen/sulfur of N/S-CNB with three-dimensional hierarchical bundled array structure yields distensible interlayer spaces to buffer the volume expansion during K+insertion/extraction,offers more electrochemical active sites to obtain a high specific capacity,and provides efficient channels for fast ion/electron transports.Therefore,the N/S-CSB anode achieved high reversible specific capacity of 365 mAh/g obtained at 50 mA/g after 200 cycles with a coulombic efficiency(CE)close to 100%,high rate performance and long cycle stability.Moreover,the in-situ Raman spectra indicated outstanding reaction kinetics of as-prepared N/S-CSB anode. | Jinhui Cao Jiang Zhong Hanjiao Xu Shengyang Li Hongli Deng Tao Wang Ling Fan Xinghui Wang Lei Wang Jian Zhu Bingan Lu Xidong Duan | 2022 | Nano Research2022,15,3: | 1 |
