Research progress on cellulose-based separators for aqueous zinc-ion batteries
摘要
Abstract
Aqueous zinc-ion batteries(AZIBs)are significant for the development of the battery and energy industry,and have attracted much attention as a new generation energy storage system owing to their abundant raw materials,high theoretical specific capacity,and low redox potential.The separator is an important part of zinc-ion batteries,critically influencing their electrochemical performance and cycle life.To address issues such as the high cost,uneven pore size distribution and poor mechanical strength of glass fiber separators,the development of low-cost and high-performance cellulose-based separators has become a key direction.Cellulose offers advantages such as low cost,high mechanical strength,good wettability,and strong modifiability,making it a highly promising material for zinc-ion battery separators.The development of cellulose-based separators for aqueous zinc-ion batteries not only propels the research on energy storage batteries forword,but also contributes to energy conservation and emission reduction. With the development of membrane science and technology,the preparation methods of different types of cellulose-based separators have been developed significantly,including coating,phase inversion,casting,filtration,electrospinning and other methods.These methods have their own advantages.For example,electrospinning enables the fabrication of nanoscale fibers,thereby endowing separators with higher porosity,a higher specific surface area,and a reduced thickness.Additionally,various material selections,including cotton cellulose,bamboo cellulose,and bacterial cellulose,can effectively regulate the deposition of zinc ions and promote electrochemical performance such as cycling stability and charge/discharge rates.Furthermore,different sizes of cellulose such as microfibrillated cellulose and nanocellulose can also affect the mechanical and electrochemical performance.The research of cellulose materals has advanced rapidly,with emphasis on introducing the regulatory mechanisms for issues such as zinc dendrite growth and hydrogen evolution corrosion.These achievements have made it possible to commercialize the cellulose separator. In spite of the considerable development of cellulose-based separators,the challenges still need to be solved in aqueous zinc-ion battery separators such as zinc dendrite growth and hydrogen evolution corrosion.These side effects will significantly affect the electrochemical performance of the battery.Additionally,the preparation,storage and long-term transportation of micro-nanofibrillated cellulose encounter problems such as agglomeration.Further research is needed to reduce costs and enable cost-effective preparation,storage,and transportation of nanofibrillated cellulose.Therefore,the commercialization of large-scale production of cellulose-based aqueous zinc-ion batteries remains difficult.The problems faced by cellulose-based separators are identified.Addressing these challenges will pave the way for a promising and optimistic outlook on the future commercialization of cellulose-based aqueous zinc-ion batteries.关键词
