摘要
考察了电解液中锂盐浓度对高功率锂离子电池倍率放电及高低温性能的影响。锂盐浓度为0．9～1．5mol／L时，浓度越高越有利于大电流放电，但高于1．4mol／L后，倍率放电中值电压的提升趋向平缓；在-20℃下以170mA（1C）放电，1．2mol／L时的性能最好。
Effects of lithium salt concentration on rate discharge, high-low temperature performance of high-rate discharge Li-ion battery were investigated. When the lithium salt concentration was 0.9 - 1.5 mol/L, the higher concentration was benefit to heavy load discharge, but when higher than 1.4 mol/L, the increasing of rate discharge middle vohage trended gentle. When discharged with 1 C （170 mA） at -20 ℃, the performance was the best with 1.2 mol/L.
