Title
(EN) A NICKEL METAL HYDRIDE BATTERY CONTAINING A MODIFIED DISORDERED MULTIPHASE NICKEL ALUMINUM BASED POSITIVE ELECTRODE
(FR) BATTERIE D'HYDRURE DE NICKEL METAL COMPORTANT UNE ELECTRODE POSITIVE A BASE DE NICKEL-ALUMINIUM MULTIPHASE MODIFIE OBTENUE DE MANIERE DESORDONNEE
Abstract
(EN)
A disordered positive electrode for use in an alkaline rechargeable electrochemical cell comprising: a solid solution nickel aluminum hydroxide material having a multiphase structure. This solid solution nickel hydroxide material is a multiphase structure that comprises at least one microcrystalline $g(a)-phase material. Phase stabilizers and conductivity enhancers can be included to further stabilize the material.
(FR)
ELectrode positive obtenue de manière désordonnée, destinée à être utilisée dans un élément électrochimique rechargeable alcalin comprenant: un hydroxyde de nickel-aluminium en solution solide présentant une structure multiphase. Cet hydroxyde de nickel en solution solide est une structure multiphase qui renferme au moins un matériau monocristallin à phase $g(a). Des stabiliseurs de phase et des améliorateurs de conductivité peuvent être inclus pour accroître la stabilité du matériau.
