固态电池技术发展现状综述

The Summarize of Current Development Status of Solid State Battery Technology

车辆电动化发展要求动力电池具有高能量密度、高安全和高可靠性。液态电解质动力电池能量密度提升空间不足,严重影响车辆的续航里程,存在起火、漏液的安全隐患,因此,越来越多的企业进行固态电池的技术研发。采用固态电解质的动力电池不仅彻底解决了安全性问题,同时可显著提高动力电池的能量密度,满足车辆的长续航里程要求。总结了固态电池的技术发展现状,分析了国内外固态电池技术的难点,为车企应用推广固态电池提供理论参考依据。

The development of vehicle electrification requires batteries to have high energy density,high safety,and high reliability characteristics.There is insufficient space for energy density improvement,which seriously affects the vehicle's range.Liquid electro-lyte power batteries have safety hazards such as ignition and leakage.Therefore,more and more companies are conducting technological research and development on solid state batteries.The use of solid electrolyte in batteries not only completely solves safety issues,but also greatly improves the energy density of the power battery,meeting the requirements of the vehicle's long range.It analyzes the diffi-culties of solid state battery technology at home and abroad,summarizes the current development status of solid state battery technolo-gy,and provides a theoretical reference for the application and promotion of solid state batteries by vehicle enterprises.
