Development of Key Material System for Solid-State Batteries
摘要
Abstract
The solid-state battery is crucial for achieving the next-generation batteries that possess high energy density,high safety,long service life,and low cost.Major countries and regions are rapidly advancing the research and industrial application of solid-state batteries.This study reviews the development status of key material systems for solid-state batteries worldwide from the aspects of technological,industrial,and supporting systems.It analyzes the technical development paths,industrial scales,and supporting systems of solid-state batteries in countries and regions including the United States,Europe,Japan,and Republic of Korea,and summarizes the development status and goals of the key material system for solid-state batteries in China.Our study reveals that the solid-state batteries are currently in a promotion stage in China,facing challenges in terms of key raw materials,breakthroughs in critical scientific and technological bottlenecks,mass production,and industrial application.To promote the development of solid-state batteries in China,we propose the following suggestions:(1)adhering to an overall staged-development strategy for solid-state batteries,(2)establishing national-level development programs and major scientific and technological projects for solid-state batteries,(3)promoting the construction of technology research and development institutions for solid-state batteries,(4)encouraging the market application and industrial transformation of solid-state batteries,and(5)optimizing the solid-state battery ecosystem.关键词
