Disclosed are an electrode active material, of which the stability is improved by adjusting an acid site of a surface of the electrode active material, an electrode containing the electrode active material, having a surface coated with a compound having an acid site, or mixed with the compound having the acid site and an electrode material, and an electrochemical device having the electrode to enhance its performance. By adjusting the acid site on the surface of the electrode active material, the side reaction with the electrolyte is decreased, and the structure stability of the electrode active material is secured, thereby enhancing the performance of the battery.
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.
