   四氟硼酸锂(LiBF4)具有较好化学稳定性和热稳定性,对水分不太敏感,但不良导电性限制了LiBF4基电解质体系的应用。LiBF4主要作为LiPF6基电解质体系添加剂,改善循环寿命,提高了锂离子电 池性能。此外,LiBF4对铝箔的钝化能力也相当优秀,因此作为成膜添加剂,LiBF4已广泛应用于当前的电解液中。而且添加LiBF4之后可拓宽锂离子电池的工作温度范围,提高电池的高低温放电性能,LiBF4比LiPF6更适合在极端环境(高温或低温)下使用。


      LiBF4 has the excellent chemical stability and thermal stability, insensitive to moisture. But the low conductivity limited its application range. Generally, LiBF4 as the additive of LiPF6 based electrolyte system can enhance the performance and cycle life of Li+ battery. Furthermore, LiBF4’s passivation ability to Al foil is also very good, so it can be used as the film forming addictive. Addition of LiBF4 can widen the Li+ battery’s working temperature range, enhance the Li+ battery’s working performance in high or low ambient temperature. So, compared with LiPF6, LiBF4 is more suitable for using under extreme environment (high or low temperature).
