研究了使用功率型和常规电解液的动力锂离子电池的倍率放电特性、放电效率及循环性能。在常温中倍率放电时,功率型电解液与常规电解液相比没有明显优势;在高倍率放电时,功率型电解液可以提高电池的放电效率;但在高倍率持续放电时,电池有一定程度的发热;功率型电解液的循环性能比常规电解液好,主要是因为含有添加剂碳酸亚乙烯酯(VC)、亚硫酸丙烯酯(PS)。2.0%VC和1.5%PS配合使用对提高电池的放电效率和循环性能最好。

The rate discharge ability,discharge efficiency and cycle performance of power Li-ion battery used high-power and com-mon electrolyte were studied. High-power electrolyte had no superiority to the common electrolyte when medium rate discharged in normal temperature. When high rate discharged,high-power electrolyte could enhance the discharge efficiency,but the batteries would have some heating in continuous high rate discharge. The cycle performance of high-power electrolyte was better than common electrolyte,since it contained vinylene carbonate(VC)and trimethylene sulfite(PS). The match usage of 2.0%VC and 1.5%PS was best to enhance discharge efficiency and cycle performance of the battery.
