摘要:隔膜是电池的重要组成部分，传统的商用聚烯烃隔膜不仅润湿性和热稳定性较差，并且原料不可再生。为了满足可持续发展的需求，具有较好热稳定性、可降解以及可再生等优点的生物质纤维基锂电池隔膜受到广泛关注。本文概述了纤维素微米纤维基隔膜、纤维素纳米纤维基隔膜以及其他种类生物质纤维基锂电池隔膜的研究进展，并对该领域未来的研究方法和发展方向进行了展望。

Abstract:The separator is an important part of the battery and also plays a key role.Traditional commercial polyolefin separators not only have poor wettability and thermal stability， but the raw materials are not renewable.In order to meet the needs of sustainable development， biomass fiber-based lithium battery separators with good thermal stability， degradability and regeneration have attracted extensive attention.The research progress of cellulose microfiber-based separator， cellulose nanofiber-based separator and other kinds of biomass fiber-based lithium battery separators are summarized， and the future research methods and development direction in this field are discussed.
