    • Provided is a method of designing an electrolyte composition including a nonaqueous organic solvent mixture and a lithium salt to obtain an optimal composition ratio of components of the electrolyte composition for a high charging/high-output discharging secondary battery. The method includes: selecting components of the nonaqueous organic solvent mixture; determining composition ratio ranges of the selected components satisfying such conditions that an average dielectric constant, an average viscosity, and an average boiling point satisfy predetermined boundary values; dividing the ranges of the composition ratios into a plurality of groups; selecting a representative composition ratio of each of the groups; adding a lithium salt to a nonaqueous organic solvent mixture having the representative composition ratio to prepare an electrolyte composition; and measuring properties of the electrolyte composition to determine a composition ratio of an electrolyte composition having predetermined properties.
    • 提供一种设计包含非水有机溶剂混合物和锂盐的电解质组合物的方法,以获得用于高充电/高输出放电二次电池的电解质组合物的组分的最佳组成比。 该方法包括:选择非水有机溶剂混合物的组分; 确定所选择的组分的组成比范围满足平均介电常数,平均粘度和平均沸点满足预定边界值的条件; 将组成比的范围除以多个组; 选择每个组的代表性组成比; 向具有代表性组成比的非水有机溶剂混合物中加入锂盐以制备电解质组合物; 以及测定电解质组合物的性质以确定具有预定特性的电解质组合物的组成比。
