摘要
LiBF4基电解质的热稳定性较好,对环境水分不太敏感,有希望发展成为被民用、军事、三航领域微型、储能及动力锂离子电池广泛采用的优秀电解质体系。本文综述了近期在改善LiBF4的电导率、拓宽应用温度范围、促进SEI膜的形成、提高其电解液电导率及与电极材料的相容性等方面所取得的进展,并对其未来发展方向作了展望。
To avoid the drawbacks of LiPF6-based electrolytes such as its moisture sensitivity, thermal instability, narrow operating temperature range and easiness to release PF5, much attention has been paid to developing new type electrolytes. Attempts to develop LiBF4-based electrolytes are among one of them. Electrolytes based on LiBF4 are thermally more stable and insensitive to moisture, which would probably make it to become a promising electrolyte system for civilian, military, navigation, aviation and aeronautic use in miniature, energy storage and vehicle Li-ion batteries. Progress in studies of LiBF4-based electrolytes recently such as attempts to improve its conductivity, to extend its temperature operation, to help form stable SEI film and its compatibility with electrodes are reviewed. Future prospect of LiBF4-based electrolytes is also discussed.
