Abstract

L'invention concerne des particules électrochimiquement actives appropriées pour être utilisées comme matériau actif dans une cathode d'une cellule électrochimique au lithium-ion qui comprennent : une pluralité de cristallites comprenant une première composition contenant du lithium, du nickel et de l'oxygène ; et une limite de grain entre des cristallites adjacents de la pluralité de cristallites et comprenant une seconde composition contenant du lithium, du nickel et de l'oxygène ; la limite de grain ayant une affinité électrochimique plus élevée pour le lithium que les cristallites. L'affinité électrochimique plus élevée pour le Li conduit à une rétention de Li accrue dans les limites de grain pendant la charge par rapport aux cristallites en vrac et stabilise la structure des limites de grain et des cristallites pour une stabilité de cyclage améliorée sans perte sensible de capacité.
