The excellent performance makes it have good research and development prospects in the new generation of lithium ion batteries.
As a solid electrolyte having a promising safety, some conventional polymer materials including polymers of poly (ethylene oxide) (PEO), poly (vinylidene fluoride) (PVDF), poly (methyl methacrylate) (PMMA), poly (acrylonitrile) (PAN), polyvinylidene fluoride-hexafluoropropylene (PVDF-HFP), etc., or a mixture of these polymers have been widely studied. However, because the crystallinity of PEO, PVDF and PVDF-HFP is high, which results in low ionic conductivity, poor film-forming property of PMMA, which results in poor performance, and poor lithium ion conductivity of PAN, which results in poor charge and discharge properties, which cause limited application in lithium ion batteries, a novel polymer electrolyte needs to be developed for application in lithium ion batteries. In addition, almost all polymer electrolytes are prepared by using a solvent. However, this method is complicated in manufacturing process, high in cost and environmentally friendly.
