Abstract

La présente invention concerne une nouvelle manière de doper des matériaux de cathode en couches dans des batteries au lithium-ion. À l'aide d'une stratégie de dopage "à entropie élevée" ou "cocktail'', plus de quatre éléments d'impureté peuvent être introduits dans les matériaux hôtes. La présente invention applique cette stratégie de dopage à entropie élevée à un matériau d'oxyde en couches à haute teneur en nickel et à un matériau riche en lithium-manganèse. Cette nouvelle stratégie de dopage à entropie élevée permet aux matériaux d'oxyde en couches utilisés dans l'électrode positive d'une batterie au lithium-ion d'avoir une densité d'énergie élevée, un cycle de longue durée de vie et une dépendance réduite au cobalt onéreux et toxique, tous ceux-ci étant des attributs souhaités pour améliorer la performance des batteries au lithium-ion et réduire leur coût.
