POSITIVE ELECTRODE MATERIAL FOR LITHIUM SECONDARY CELL

摘要

A first positive electrode material for a lithium secondary cell which comprises an electroconductive polymer having an amino group, a compound capable of forming a hydrogen bonding and a proton acid. The above first positive electrode material uses an electroconductive polymer, such as polyaniline, and exhibits stable electroconductivity over a long period of time. A second positive electrode material for a lithium secondary cell, which comprises an electroconductive polymer and LiNiO₂ and/or LiFePO₄. The second positive electrode material uses an electroconductive polymer, such as polyaniline, and also exhibits high charge and discharge capacity.
