摘要
锂空气电池的理论比能量高达3 505 Wh/kg,是新一代高比能电池的研发热点,有望应用于清洁能源、电动汽车及其他储能系统上。当前普遍研究的以有机电解液为基础的非水系锂空气电池存在着电解液挥发、分解以及锂负极粉化腐蚀等问题,这些问题极大地限制了锂空气电池的发展。固体电解质有高电位下稳定、不挥发、致密坚固的特点,使用固体电解质有望从根本上解决上述问题,推动锂空气电池的发展。从固体电解质的选择,固体电解质复合空气正极,电池性能等方面对近年国内外的研究进行总结,并对未来的研究方向进行展望。
The theoretical specific energy of Li-air battery is 3 505 Wh/kg, which is much higher than traditional Li-ion batteries. So, it has attracted a great interest for a new generation batteries which is essential for clean energy storage, electric vehicles, and other high-energy storage applications. However, there are significant technical challenges which restrict the development of practical lithium-air batteries: the instability of electrolytes and the corrosion of the lithium. The solid-state electrolytes with the advantages of stability, nonvolatility and sturdiness are promising to solve these problems completely, which is a great development of lithium-air batteries. The application of the solid-state electrolytes including the materials and the cathode was reviewed, and development forecast for the soild-state electrolytes was suggested.
