General Formula (I)
Provided is an all solid state secondary-battery additive comprising a polyalkylene carbonate (I) represented by general formula (I), and by providing such additive, properties such as the charge-discharge capacity and interfacial resistance of an all-solid-state secondary battery are improved. (In general formula (I), R1 and R2 are each a C1-10 chain-like alkylene group or C3-10 cycloalkylene group, m is 0, 1, or 2 and n is an integer of 10 to 15000, and each R1, R2 and m in the polyalkylene carbonate (I) chain is independently the same or different.)
通式 (I)
本发明提供了一种全固态二次电池添加剂,该添加剂由通式(I)代表的聚碳酸亚烷基酯(I)组成,通过提供这种添加剂,可改善全固态二次电池的充放电容量和界面电阻等性能。(在通式(I)中,R1 和 R2 各为 C1-10 链状亚烷基或 C3-10 环亚烷基,m 为 0、1 或 2,n 为 10 至 15000 的整数,且聚碳酸亚烷基酯(I)链中的每个 R1、R2 和 m 独立地相同或不同)。
