Patent

CA 2361391

The invention provides an electrochemically active material comprising particles of spinel lithium manganese oxide having on the surface of each particle cationic metal species bound to the spinel at anionic sites of the particle surface; where the cationic metal species includes a metal selected from the group consisting of transition metals, non-transition metals having a +3 valence state, and mixtures thereof. The active material is characterized by a reduced surface area and increased capacity expressed in milliamp hour per gram as compared to the spinel alone.

Cette invention se rapporte à un matériau actif du point de vue électrochimique, qui comprend des particules d'oxyde de manganèse-lithium en spinelle comportant sur la surface de chaque particule des espèces métalliques cationiques fixées au spinelle en des sites anioniques de la surface des particules; ces espèces métalliques cationiques comprenant un métal choisi dans le groupe constitué par des métaux de transition, des métaux autres que des métaux de transition ayant un état de valence égal à +3 et des mélanges de ceux-ci. Par rapport au spinelle seul, ce matériau actif se caractérise par une superficie réduite et par une capacité accrue exprimée en milliampère-heure par gramme.
