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 a promising electrolyte system for civilian, military, navigation, aviation and aeronautic use in miniature, energy storage and vehicle Li-ion batteries. Progresses 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.
