摘要
钠硫电池作为一种重要的储能技术,已在全球储能市场拥有GW·h级的装机容量,然而其安全问题一直倍受关注,成为制约其产业大规模发展的一大要素。本文首先介绍储能钠硫电池的结构、工作原理及其工程化发展现状,再针对高温钠硫电池应用中存在的安全隐患问题,从电池的电芯层面到模组层面,提出提高钠硫电池安全性能的解决策略。着重综述了基于固体电解质增韧、降低固体电解质局部电流密度、增强封接材料的热机械稳定性、电芯外壳防腐蚀、电池保温箱热管理与火源阻隔等安全策略的材料和结构设计方面的研发进展,最后对高安全性钠硫电池未来在低温化和液流化的研发方向作出设想和展望。
As an important energy storage technology,sodium sulfur battery has GWh-class installed capacity in the global energy storage market.However,its safety problem has become a major factor restricting its further development.This paper first introduces the structure,operating principle and commercial development status of sodium sulfur battery,and then in view of the potential danger of this battery,proposes the resolution strategies based on the cell level and the module level.The strategies of toughening solid electrolyte,reducing local current density,enhancing thermal mechanical stability of sealing materials,anti-corrosion of cell shell,thermal management and fire source isolation of the battery incubator are analyzed.The research and development of materials and structure designs involving these strategies are reviewed,and the future research directions of sodium sulfur battery on low temperature type and high temperature flow type are presented finally.
