摘要
可充电锂离子电池具有许多优点,如体积和质量能量密度高,自放电率低,因此广泛应用于3C领域、电动汽车以及固定式能量存储等方面。为满足在上述领域的应用,对锂离子电池循环性能和存储性能有了更高要求,因而对锂离子电池老化机制越发重视。本文综合国内外取得的一些研究进展,对锂离子电池的正极、负极、表/界面老化机理进行了综述和分析。
Granted that various outstanding properties of rechargeable lithium-ion batteries,like high volume/mass energy density and low self-discharge rate,promote their wide-spread applications,such as 3 C fild,electric vehicles and fixed energy storage,etc.Simultaneously,more requirements were proposed for different applying conditions,especially for cyclic and storage performances,thus,more attentions were paid for the investigation of aging mechanism of lithium-ion batteries.The aging mechanism of positive electrode,negative electrode and surface/interface of lithium-ion batteries was reviewed and analyzed based on the research developments all over the world.
