Abstract
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.)
