Title:
POLYMER SOLID ELECTROLYTE COMPOSITION
Document Type and Number:
Japanese Patent JP3763188
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain the subject composition capable of manifesting a high ionic conductivity and a high mechanical strength by including components comprising a thermoplastic polyester elastomer and a rubber containing a polar group, and an electrolytic solution dissolving an alkali metal salt.
SOLUTION: This composition comprises (A) (i) 20-90 wt.% thermoplastic polyester elastomer and (ii) 10-80 wt.% rubber having a polar group, (B) an electrolyte obtained by dissolving an alkali metal salt. The component (i) preferably has ≤55 shore D hardness, and ≤200°C melting point. For example, an acrylonitrile-butadiene rubber, an ethylene-acryl rubber, etc., are preferable as the component (ii). The component B is preferably obtained by dissolving an electrolyte comprising a lithium salt in a nonaqueous solvent. The composition can be expected to be used as the ionic conductor used for a lithium secondary battery, etc.
