  • Positive Electrode Material for Lithium Secondary Battery
    Publication number: 20090095942
    Abstract: It is a first object of the present invention to provide a lithium secondary battery using a conductive polymer such as polyaniline, which exhibits a stable electrical conductivity over a long time. To achieve the first object, there is provided a positive electrode material for a lithium secondary battery, comprising an electrically conductive polymer having an amino group, a hydrogen bonding compound, and a protonic acid. Further, it is a second object of the present invention to provide a lithium secondary battery exhibiting a high charge-discharge capacity while using a conductive polymer such as polyaniline. To achieve the second object, there is provided a positive electrode material for a lithium secondary battery, comprising an electrically conductive polymer, and LiNiO2 and/or liFePO4.
