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.

Zinc ion hybrid capacitors(ZIHCs), which integrate the features of the high power of supercapacitors and the high energy of zinc ion batteries, are promising competitors in future electrochemical energy storage applications. Carbon-based materials are deemed the competitive candidates for cathodes of ZIHC due to their cost-effectiveness, high electronic conductivity, chemical inertness, controllable surface states, and tunable pore architectures. In recent years, great research efforts have been devoted to further improving the energy density and cycling stability of ZIHCs. Reasonable modification and optimization of carbon-based materials offer a remedy for these challenges. In this review, the structural design, and electrochemical properties of carbon-based cathode materials with different dimensions, as well as the selection of compatible, robust current collectors and Separators for ZIHCs are discussed. The challenges and prospects of ZIHCs are showcased to guide the innovative development of carbon-based cathode materials and the development of novel ZIHCs.

Lithium-ion batteries(LIBs)are the most important electrochemical energy storage devices due to their high energy den-sity,long cycle life,and low cost.During the past decades,many review papers outlining the advantages of state-of-the-art LIBs have been published,and extensive efforts have been devoted to improving their specific energy density and cycle life performance.These papers are primarily focused on the design and development of various advanced cathode and anode electrode materials,with less attention given to the other important components of the battery.The“nonelectroconductive”components are of equal importance to electrode active materials and can significantly affect the performance of LIBs.They could directly impact the capacity,safety,charging time,and cycle life of batteries and thus affect their commercial application.This review summarizes the recent progress in the development of nonaqueous electrolytes,binders,and separa-tors for LIBs and discusses their impact on the battery performance.In addition,the challenges and perspectives for future development of LIBs are discussed,and new avenues for state-of-the-art LIBs to reach their full potential for a wide range of practical applications are outlined.

Separators are indispensable components of modern electrochemical energy storage devices such as lithium-ion batteries(LIBs).They perform the critical function of physically separating the electrodes to prevent short-circuits while permitting the ions to pass through.While conventional Separators using polypropylene(PP) and polyethylene(PE) are prone to shrinkage and melting at relatively high temperatures(150℃ or above) causing short circuits and thermal runaway,Separators made of thermally stable polyimides(PIs) are electrochemically stable and resistant to high temperatures,and possess good mechanical strength-making them a promising solution to the safety concerns of LIBs.In this review,the research progress on PI Separators for use in LIBs is summarized with a special focus on molecular design and microstructural control.In view of the significant progress in advanced chemistries beyond LIBs,recent advances in PI-based membranes for applications in lithium-sulfur,lithium-metal,and solid-state batteries are also reviewed.Finally,practical issues are also discussed along with their prospects.

Fast thermal responsive Separators toward long-life and safe lithium metal batteries

Nano Research 2024年第4期17卷 2746-2754页

Lithium metal batteries(LMBs)have been extensively investigated during the past decades because of their ultrahigh energy densities.With the increasing demand for energy density,however,the safety issue of LMBs has become a significant challenge.In particular,localized areas of increased temperature(namely,hotspots)may be induced and even exacerbated within LMBs by uneven current distribution,internal short circuits,or inadequate heat dissipation,which significantly sacrifices battery safety and cycle life.Here,we report the rational design and fabrication of a fast thermal responsive separator capable of inhibiting the growth of lithium dendrites and mitigating thermal propagation,thereby reducing the risk of thermal runaway.The as-achieved separator comprises both an electrospun membrane using a phase change material with superior thermal-storage ability and a thermally conductive modification layer of hexagonal boron nitride nanosheets with a fast heat-transfer feature.It is demonstrated that such a unique integration of heat conduction and heat storage enables the functional separator with attractive abilities to mitigate hotspots and inhibit the growth of lithium dendrites upon the cycling of LMBs.Moreover,pouch cells with the thermal-responsive separator,as well as numerical simulations,verify much enhanced safety and cycle life of LMBs.This work may offer a new conceptual design of intelligent Separators that acts as a functional unit encapsulated within a single cell to boost in-situ thermal management,which will help to develop high-safety and energy-dense LMBs.

International Journal of Minerals,Metallurgy and Materials 2013年第6期20卷 598-603页

作者： Hong-yan Guan Fang Lian Yan Ren Yan Wen Xiao-rong Pan Jia-lin Sun School of Materials Science and Engineering University of Science and Technology Beijing

Membranes of polypropylene （PP）, PP coated with nano-A1203, PP electrospun with polyvinylidene fluoride- hexafluoropropylene （PVdF-HFP）, and trilayer laminates of polypropylene-polyethylene-polypropylene （PP/PE/PP） were comparatively studied. Their physical properties were characterized by means of thermal shrinkage test, liquid electrolyte uptake, and field emission scanning electron microscopy （FESEM）. Results show that, for the different membranes as PP, PP coated with nanowA1203, PP electrospun with PVdF-HFP, and PP/PE/PP, the thermal shrinkages are 14%, 6%, 12.6%, and 13.3%, while the liquid electrolyte uptakes are 110%, 150%, 217%, and 129%, respectively. In addition, the effects on the performance of lithium-ion batteries （LiFePO4 and LiNil/3Col/3Mn1/302 as the cathode material） were investigated by AC impedance and galvanostatic charge/discharge test. It is found that PP coated with A1203 and PP electrospun with PVdF-HFP can effectively increase the wettability between the cathode material and liquid electrolyte, and therefore reduce the charge transfer resistance, which improves the capacity retention and battery performance.

With the advantages of intrinsic safety,good affordability,environmental friendliness,moderate energy density,and large power density,aqueous zinc ion batteries(AZIBs)have gained considerable research interest.However,zinc dendrites,hydrogen evolution,inert byproducts,and zinc metal corrosion severely hinder practical applications of AZIBs.In order to address these issues,many research works have been carried out to modify the interface between zinc metal anode and aqueous electrolyte.In fact,the interface engineering takes effect at the surface and near the surface of separator.However,a specialized review on the Separators of AZIBs is still lacking.Herein,basic requirements of Separators and recent advances on the modification strategies including employment of functional groups,establishment of surface coatings,construction of hybrid architectures,regulations of porosity,and utilization of bipolar membrane are reviewed.Besides,the perspectives for further investigations on the Separators of AZIBs are outlined.This review could offer useful guidance for the future explorations of Separators for AZIBs.

Enhancing anchoring and catalytic conversion of polysulfides by nitrogen deficient cobalt nitride for advanced lithium-sulfur batteries

引用

Journal of Energy Chemistry 2022年第10期31卷 407-415,I0010页

作者： Min Luo Yu Bai Rui Sun Meixiu Qu Mengyuan Wang Zhanfeng Yang Zhenhua Wang Wang Sun Kening Sun Advanced Research Institute of Multidisciplinary Science Beijing Institute of TechnologyBeijing 100081China Beijing Key Laboratory for Chemical Power Source and Green Catalysis School of Chemistry and Chemical EngineeringBeijing Institute of TechnologyBeijing 100081China

While lithium-sulfur(Li-S)battery has attracted remarkable attention owing to the high theoretical capacity,its practical application is still hindered by the shuttle and sluggish conversion kinetics of intermediate lithium polysulfides(Li PSs).Defect engineering,which can regulate the electronic structure and in turn influence the surface adsorption and catalytic capability,has been regarded as a feasible strategy to deal with the above challenges.However,few studies on nitrogen vacancies and their mechanisms are reported.Herein,cobalt nitride with nitrogen vacancies grown on multi-walled carbon nanotube(CNTCo N-VN)is designed and applied as the separator modification material to investigate the enhancing mechanism of nitrogen vacancies on Li-S batteries.The experimental evidence and theoretical calculation indicate that the introduction of nitrogen vacancies into cobalt nitride can enhance the chemical affinity to Li PSs and effectively hamper the shuttle effect.Meanwhile the reduced band gap of the d-band center of Co and p-band center of N for CNT-Co N-VNand the promoted diffusion of Li^(+) can expedite the solid-liquid and liquid-liquid conversions of sulfur species.Due to these superiorities,the cell with CNT-Co NVNmodified separator delivers a favorable initial capacity of 901 m Ah g^(-1)and a capacity of 660 m Ah g^(-1)can be achieved after 250 cycles at 2 C.This work explores the application of metal nitride with nitrogen vacancies and sheds light on the development of functional Separators for high-efficient Li-S batteries.
