电化学双电层电容器失效机理的研究进展
Research progress on failure mechanism of electrochemical double layer capacitors
摘要
Abstract
Electrochemical double layer capacitor(EDLC)has attracted much attention due to its high power density,long cycle life and rapid charging capacity.However,the stability and reliability of EDLC are critical for practical applications.To improve the stability and extend life,it is important to understand the mechanism of performance attenuation and failure.This paper discusses the failure criteria of EDLC and methods for monitoring and in-situ electrochemical characterization of performance degradation.By reviewing research progress on the failure of EDLC,it focuses on key components such as electrode materials,electrolyte,electrode/electrolyte interface and current collector,with the purpose of revealing the failure phenomena and mechanisms in different systems.Finally,we look forward to the development direction and challenges of high stability EDLC,emphasizing the development and characteristics of new materials,and providing strategies for performance optimization and application expansion.关键词
