摘要

相对于传统锂离子电池,全固态锂电池具有安全性能高、循环寿命长、能量密度高等优点,是目前锂电池研究领域的热点之一.作为全固态锂电池的核心组成部分,固体电解质是实现全固态锂电池高性能的关键材料.本文设计了一种高分子-锂盐-陶瓷的复合物固体电解质.通过多种固体核磁共振(NMR)方法研究了该材料中高分子-陶瓷的界面层结构和界面高分子链段的分子运动.

Abstract

All solid state lithium-ion batteries have the advantages of high safety, long cycle life and high energy density, as compared with the conventional lithium-ion batteries, and have been attracting more and more research interest. Solid electrolyte is a crucial component of all solid state lithium-ion batteries, which largely determine the performance of the batteries. In this work, a polymer-lithium-ceramics complex was designed and synthesized. The structure and dynamics of the polymer-ceramic interface was studied with solid-state NMR techniques.
