電気化学デバイス用正極および電気化学デバイス、ならびにこれらの製造方法
Document Type and Number:
Japanese Patent JP7045616
Kind Code:
B2
Abstract:
A positive electrode for electrochemical device includes a positive current collector and a positive electrode material layer supported on the positive current collector. The positive electrode material layer includes a positive electrode active material. The positive electrode active material includes an inner core portion containing polyaniline and a surface layer portion containing poly(3,4-ethylenedioxythiophene) and polythiophene. The inner core portion is fibrous or grain-aggregate, and the surface layer portion covers at least a part of the inner core portion. Furthermore, an electrochemical device includes the above-described positive electrode, a negative electrode including a negative electrode material layer that occludes and releases a lithium ion, and a nonaqueous electrolytic solution having lithium ion conductivity.
