A novel high-performance gel polymer electrolyte membrane basing on electrospinning technique for lithium rechargeable batteries

- We chose thermoplastic polyurethane (TPU) and poly(vinylidene fluoride) (PVdF) as matrixs for gel polymer electrolytes (GPEs).
- The TPU/PVdF based GPEs not only can have relatively high ionic conductivity but also have good mechanical stability at room temperature.
- In addition, we prepared the polymer films with electrospun technology.
- Our study provides very helpful information to solve the safety problem of lithium ion battery.
