Abstract:
Gel polymer electrolytes (GPEs) have regarded as one of promising solutions to safety issues of lithium ion batteries (LIBs) generally related to organic liquid electrolytes and polyolefin microporous separators. However, the mechanical strength of the prepared gel membranes is much lower than that of the commercial separators, which exclude them from practical applications on large scale energy storage systems. The superior features of nonwovens such as low price, high porosity, good wettability to liquid electrolytes, simple manufacture process, strong mechanical strength and so on provide them alternative solutions in reinforcement of GPEs. By using nonwovens, many new technologies, such as trilayer or sandwich structures, interpenetrating networks, forming composites and so on, have been explored by us to improving the mechanical properties of GPEs for LIBs. Meanwhile, the electrochemical performance of the prepared composite GPEs have also been discussed.
