Title:
ELECTRODE FOR NONAQUEOUS ELECTROLYTE BATTERY
Document Type and Number:
WIPO Patent Application WO/1997/029522
Kind Code:
A1
Abstract:
A highly safe electrode for a nonaqueous electrolyte battery, showing reduced shelf depreciation and good charge/discharge characteristics at high rates, can be provided in the following four types: (1) an electrode for a nonaqueous electrolyte battery provided with the particles of an active material coated with porous films, (2) an electrode for a nonaqueous electrolyte battery provided with an active material holding a filler in pores, (3) an electrode for a nonaqueous electrolyte battery holding a filler in pores formed in an active material which expands or contracts when a battery is charged or discharged, or (4) the electrode for a nonaqueous electrolyte battery described in (1) above, wherein the porous films is ionic-conduction films.
