摘要

Abstract

Because of its superior safety and excellent processability

solid polymer electrolytes (SPEs) have attracted widespread attention. In lithium based batteries

SPEs have great prospects in replacing leaky and flammable liquid electrolytes. However

the low ionic conductivity of SPEs cannot meet the requirements of high energy density systems

which is also an important obstacle to its practical application. In this respect

escalating charge carriers (

i.e.

) and Li

transport paths are two major aspects of improving the ionic conductivity of SPEs. This article reviews recent advances from the two perspectives

and the underlying mechanism of these proposed strategies is discussed

including increasing the Li

number and optimizing the Li

transport paths through increasing the types and shortening the distance of Li

transport path. It is hoped that this article can enlighten profound thinking and open up new ways to improve the ionic conductivity of SPEs.
