摘　　要：提高能量密度是可充放锂电池研发最重要的目标。近年来,锂硫电池与锂空气电池由于具有高的理论能量密度而受到广泛关注,这两种电池仍然面临较多的科学与技术问题,处于电池开发早期研究阶段。在本文中,重点介绍了锂空气电池的基本工作原理、基本结构组成、所面临的问题和两种特殊体系的锂空气电池,同时简要介绍了锂硫电池。In recent years, rechargeable nonaqueous lithium air battery has attracted wide attention due to its very high theoretical energy density. However, it is at early stage of research because there are still many challenges for developing lithium air battery. In this paper, the concept, structures, challenges of lithium air battery and two special types of lithium air batteries are briefly summarized. In addition, the lithium sulfur battery which also belongs to rechargeable lithium metal battery and has high energy density was introduced.
