Lithium difluoro(oxalato)borate was investigated as a functional additive for non-aqueous electrolytes for lithium-ion batteries. It was found that the addition of small amount of lithium difluoro(oxalato)borate to the LiFP₆-based electrolyte can significantly improve both the capacity retention and the power retention of lithium-ion cells. Unlike other additives, lithium difluoro(oxalato)borate only slightly increased the interfacial impedance of the cells, resulting in good initial power capability. Therefore, lithium difluoro(oxalato)borate is a promising additive for high-performance lithium-ion batteries for power applications, such as hybrid electrical vehicles.

二氟草酸硼酸锂作为锂离子电池的功能添加剂

研究了二氟（草酸酯）硼酸锂作为锂离子电池非水电解质的功能添加剂。已经发现，向基于LiFP ₆的电解质中添加少量的二氟（草酸硼酸）硼酸锂可以显着提高锂离子电池的容量保持率和功率保持率。与其他添加剂不同，二氟（草酸）硼酸锂仅略微增加了电池的界面阻抗，从而具有良好的初始供电能力。因此，二氟（草酸）硼酸锂是用于电力应用（例如混合动力电动汽车）的高性能锂离子电池的有前途的添加剂。
