Title (EN) LITHIUM ION BATTERY HAVING AN IMPROVED CONSERVED PROPERTY AT A HIGH TEMPERATURE
(FR) BATTERIE LITHIUM-ION POSSEDANT UNE PROPRIETE CONSERVEE AMELIOREE A HAUTE TEMPERATURE
Abstract:
(EN) Disclosed are a cathode for a battery and a lithium ion battery. The cathode for a battery comprises a metal hydroxide having a large specific surface area as a cathode additive. The lithium ion battery comprises a cathode, an anode and a non-aqueous electrolyte, wherein the cathode comprises a metal hydroxide having a large specific surface area as a cathode additive. When a metal hydroxide having a large specific surface area is used as a cathode additive, excellent storage properties of a battery at a high temperature can be obtained, even if the metal hydroxide is used in a small amount.
(FR) La présente invention concerne une cathode destinée à une batterie lithium-ion. Cette cathode de batterie comprend un hydroxyde métallique qui possède une grande zone de surface spécifique utilisée sous forme d'additif de cathode. Cette batterie lithium-ion comprend une cathode, une anode et un électrolyte non aqueux, la cathode comprenant un hydroxyde métallique possédant une grande de zone de surface spécifique utilisée sous forme d'additif de cathode. Lorsqu'un hydroxyde métallique possédant une grande surface spécifique est utilisé comme additif de cathode, on peut obtenir d'excellentes propriétés de stockage de batterie à haute température, même si cet hydroxyde métallique est utilisé en petite quantité.
