Abstract

Matériau d'électrode actif à stabilité améliorée par réglage d'un site acide de surface de ce matériau, électrode contenant ledit matériau, à surface revêtue d'un composé à site acide, ou mélangée par combinaison entre ledit composé à site acide et un matériau d'électrode, et dispositif électrochimique utilisant l'électrode en question aux fins d'amélioration de la performance. Le réglage du site acide sur la surface dudit matériau d'électrode actif permet de diminuer la réaction secondaire avec l'électrolyte, et d'assurer la stabilité de structure de ce matériau, afin d'améliorer la performance de la batterie.
