摘　　要：把分子设计理论引入电解液设计领域,利用化学计算方法建立电解液分子结构与性能之间的内在联系,并对这种内在联系进行定量化研究,设计新的电解液组分,并进行性能预测和筛选。依据这种方法,设计了一种电解液成膜添加剂。实验结果表明:所选添加剂可改善电池的循环性能,电池经200次循环后,放电容量仍保持首次放电容量的90.6%;同时也表明利用化学计算进行电解液功能组分设计是可行的。The molecular design theory was used to the electrolyte design field, the internal relation between the molecule structure and its performance of the electrolyte was founded by chemical calculation method. The internal relation was studied quantificationally, electrolyte components were designed and their performance was forecasted and filtrated. According to this method, a new electrolyte film forming additive was designed. The test results showed that the additive could improve the cycle performance of the battery. The discharge capacity remained 90.6% of the initial discharge capacity after 200 cycles. The results also showed that this method was feasible.
