摘　　要：锂离子电池因其能量密度高、充电速度快、循环寿命长等优点而得到广泛应用,已成为手机、相机、笔记本电脑等日常电子产品的一部分,但锂离子电池仍存在的锂金属反应性高、库仑效率低、安全隐患等问题限制了锂电池的生产。改性锂离子电池隔膜可以解决此类问题,但有机材料用于锂电池隔膜改性存在着对于环境危害大等缺点,无机材料如氮化物、陶瓷材料、石墨烯及石墨烯氧化物、氢氧化物对于锂电池隔膜的改性可以显著提升隔膜安全性能、容量及循环性能,因此无机材料对于锂电池隔膜的改性已成为科研的热点。Li-ion batteries are widely used because of their high energy density,fast charging speed,long cycle life and other advantages.They have become a part of daily electronic products such as mobile phones,cameras,and notebook computers.However,the Li metal existing in Li-ion batteries still is highly reactive,Low coulomb efficiency,hidden safety hazards and other issues limit the production of Li-ion batteries.Modified Li-ion battery separator can solve such problems.But organic materials used in Li-ion battery separator modification have disadvantages such as great harm to the environment.Inorganic materials such as nitrides,ceramic materials,graphene and graphene oxides,and hydroxides used in the separators modification by substances can significantly improve the safety performance,capacity and cycle performance of the separators.Therefore,the modification of Li-ion battery separators by inorganic materials has become a hot spot in scientific research.
