外文摘要：Lithium-ion battery(LIB)industry seems to have met its bottle neck in cutting down producing costs even though much efforts have been put into building a complete industrial chain.Actually,manufacturing methods can greatly affect the cost of battery production.Up to now,lithium ion battery producers still adopt manufacturing methods with cumbersome sub-components preparing processes and costly assembling pro-cedures,which will undoubtedly elevate the producing cost.Herein,we propose a novel approach to directly assemble battery components(cathode,anode and separator)in an integrated way using electro-spraying and electro-spinning technologies.More importantly,this novel battery manufacturing method can produce LIBs in large scale,and the products show excellent mechanical strength,flexibility,thermal stability and electrolyte wettability.Additionally,the performance of the as-prepaed LiFePO4||graphite full cell produced by this new method is com-parable or even better than that produced by conventional manufacturing approach.In brief,this work provides a new promising technology to prepare LIBs with low cost and better performance.
