摘　　要：新能源汽车产业的快速发展对动力电池技术提出了更高要求,铝箔作为电池负极集流体的核心材料,其导电性和耐腐蚀性直接影响电池性能。然而,铝箔在高温、高湿等环境下容易受到腐蚀,导致电池性能下降和寿命缩短。为此,提出通过合金化设计引入镁、硅、锌等元素、应用阳极氧化和涂层技术提升铝箔的抗腐蚀性,同时优化电池设计,如电解液配方、温度管理和封装设计等,以减少腐蚀和延长使用寿命。这些策略能够显著提高铝箔的耐腐蚀性,推动新能源汽车电池技术的绿色发展。The rapid development of new energy vehicle industry puts forward higher requirements for power battery technology,while aluminium foil,as the core material of negative electrode collector,has a direct impact on battery performance in terms of its conductivity and corrosion resistance.However,aluminium foil is prone to corrosion in high temperature and high humidity environments,which leads to the degradation of battery performance and shortening of battery life.To this end,the study proposes to introduce elements such as magnesium,silicon and zinc through alloying design,applying anodic oxidation and coating technologies to enhance the corrosion resistance of aluminium foil,as well as optimising the battery design,such as electrolyte formulation,temperature management and encapsulation design,to reduce corrosion and extend the service life.These strategies can significantly improve the corrosion resistance of aluminium foil and promote the green development of new energy vehicle battery technology.
