ポリアセチレン誘導体、非水系二次電池用の正極活物質及び正極、非水系二次電池、並びに車両
Document Type and Number:
Japanese Patent JP5799781
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide: a polyacetylene derivative for a lightweight and high-capacity nonaqueous secondary battery positive electrode active material; a positive electrode active material; a positive electrode; a nonaqueous secondary battery; and a vehicle equipped with the nonaqueous secondary battery.SOLUTION: The polyacetylene derivative is represented by general formula (I) and can be used in a nonaqueous secondary battery as a positive electrode active material for the nonaqueous secondary battery, and the nonaqueous secondary battery can be incorporated into a vehicle. [In general formula (I): Rdenotes a single bond or a group comprising one or more kinds selected from the group of substituted or unsubstituted aliphatic hydrocarbon groups and substituted or unsubstituted aromatic hydrocarbon groups; R, Rand Reach independently denote a group comprising one or more kinds selected from the group of substituted or unsubstituted aliphatic hydrocarbon groups, substituted or unsubstituted aromatic hydrocarbon groups, substituents and a hydrogen group; Xand Xeach independently denote a substituent or a hydrogen group; n is an integer of ≥2 denoting a polymerization degree; and Rand Ror/and Rand Rmay bond to each other to form a ring].
