Abstract

Abstract: Compared with the conventional polyolefin separator,organic-inorganic composite separator has enough flexibility and temperature resistance as well as electrolyte affinity. In this paper ceramic composite separators for lithium-ion battery are reviewed,including advantages of this type separator compared with traditional separators,structural styles and composition materials of ceramic-based composite separator,and worldwide research and development status of ceramic composite separator. Finally the development trend of composite separator is predicted. With the development of lithium ion battery,high performance ceramic composite separator will replace traditional polyolefin separator and become the main separator to meet the needs of batteries.

Key words: lithium-ion battery, electronic materials, composites, ceramic composite separator, safety

摘要： 相对于传统锂离子电池隔膜,有机-无机陶瓷复合隔膜兼具有机材料的柔韧性、无机材料的耐温性和电解液亲和性。本文对锂离子电池用陶瓷复合隔膜进行综述,首先介绍了此类隔膜相对于传统隔膜的优势,其次对目前研究的陶瓷锂离子电池隔膜的结构形式和主要成膜材料进行了讨论,并介绍了国内外主要公司的陶瓷复合隔膜的研究和发展现状,最后对陶瓷复合隔膜的应用前景和面临的挑战进行了简要分析。鉴于该新型隔膜的优势,随着锂离子电池在高端电子产品以及动力、储能等新兴领域的发展,高安全性陶瓷复合锂离子电池隔膜必将代替传统的聚烯烃隔膜,成为主流隔膜满足人们的需要。
