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.
La présente convention concerne une cathode destinée à un accumulateur lithium ion. Cette cathode d'accumulateur comprend un hydroxyde métallique qui possède une grande zone de surface spécifique utilisée sous forme d'additif de cathode. Cet accumulateur 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 d'accumulateur à haute température, même si cet hydroxyde métallique est utilisé en petite quantité.
