(EN) LITHIUM ION BATTERY AND CATHODE ACTIVE MATERIAL THEREFOR
(FR) BATTERIE AU LITHIUM-ION ET MATÉRIAU ACTIF DE CATHODE ASSOCIÉ
Abstract
(EN)
Certain embodiments of the disclosure relate to a bimodal-type cathode active material for a lithium ion battery. The cathode active material includes a mixture of layered LiCoO2 large particles and manganese-based olivine structural small particles. The manganese-based olivine structural small particles may be represented by chemical formula LiCoxMnyFezPO4 (0≤x≤1, 0(FR)
L'invention concerne, selon certains modes de réalisation, un matériau actif de cathode de type bimodal pour une batterie au lithium-ion. Le matériau actif de cathode comprend un mélange de grandes particules stratifiées de LiCoO2 et de petites particules structurelles d'olivine à base de manganèse. Les petites particules structurelles d'olivine à base de manganèse peuvent être représentées par la formule chimique LiCoxMnyFezPO4 (0≤x≤1, 0
