Title
(EN) ELECTRODE FOR NONAQUEOUS ELECTROLYTE BATTERY
(FR) ELECTRODE POUR ACCUMULATEUR A ELECTROLYTE NON AQUEUX
Abstract
(EN)
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.
(FR)
Electrode très sûre pour accumulateur à électrolyte non aqueux, présentant une dégradation réduite en stockage et de bonnes caractéristiques de charge et de décharge à des vitesses élevées, et se présentant sous l'une des quatre formes suivantes: (1) une électrode pour accumulateur à électrolyte non aqueux qui est pourvue de particules d'un matériau actif à enrobage composé de films poreux, (2) une électrode pour accumulateur à électrolyte non aqueux pourvue d'un matériau actif contenant une charge de remplissage dans ses pores, (3) une électrode pour accumulateur à électrolyte non aqueux contenant une charge de remplissage dans des pores ménagés dans un matériau actif qui se dilate ou se contracte lorsqu'une accumulateur est chargé ou déchargé, ou (4) l'électrode pour accumulateur à électrolyte non aqueux décrite en (1) ci-dessus, dans laquelle les films poreux sont des films à conduction ionique.
