摘要
钠离子电池是未来锂离子电池的有效替代品,其能否实现快速产业化,不仅需要大的容量,还需要高安全性.本研究从失效模式、失效机理和高安全型钠离子电池开发三者的关系入手,将电池整体的失效简化为不同组成部分的失效,对钠离子电池的正极、负极、电解质、隔膜等部件进行了失效分析和总结,然后提出了一些避免失效和性能提升的方法,最后对钠离子电池失效分析的检测方法进行了介绍,并给出了简单的可供参考的流程设计.
Abstract
Sodium-ion batteries are an effective substitute for lithium-ion batteries in the future.Whether they can achieve rapid industrialization requires not only large capacity,but also high safety.This study starts from the relationship between failure mode,failure mechanism and the development of high-safety sodium-ion batteries,simplifies the failure of the entire battery into the failure of different components,and conducts research on the positive electrode,negative electrode,electrolyte,separator and other components of the sodium-ion battery.Failure analysis and summary are carried out,and some methods to avoid failure and improve performance are proposed.Finally,the detection method of sodium-ion battery failure analysis is introduced and a simple process design is given for reference.
