  • Electroconductive polymer composites for use in secondary batteries as positive electrode active materials
    Patent number: 5863454
    Abstract: An electroconductive polymer composite for use in secondary batteries as positive electrode active materials is disclosed. It includes 10-99 weight percent of a conjugated electroconductive polymer, such as polyaniline, and 90-1 weight percent of polymeric electrolyte. The latter is composed of 10-90 weight percent of an ionic salt, such as LiClO.sub.4, and 90-10 weight percent of a polymer which can form an electrolyte material with the ionic salt. The polymer, for example, can be polyvinyl alcohol or polyalkylene oxide. A method of using the electroconductive polymer composite to prepare the positive electrode of secondary batteries is also disclosed.
    Type: Grant
    Filed: January 6, 1997
    Date of Patent: January 26, 1999
    Assignee: National Science Council
    Inventors: Show-An Chen, Liang-Chang Lin
