Abstract[English]
Electrochemical energy-storage cells that include cores having cathode-active materials of both nickel-oxide (NO) type and metal-based phosphate (MP) type, wherein the MP active material is provided to increase resistance to thermal runaway. In some embodiments: the NO and MP active materials are provided on differing cathodes; cathodes include a blend of the NO and MP active materials; a weight ratio of MP active material to NO active material varies within a cathode-active layer, in some cases with a weight percentage of MP active material increasing in a direction away from a current collector; cathodes include a cathode-active layer having multiple sublayers having differing uniform blends of NO and MP materials; cathodes include discrete NO and MP layers, with some embodiments having the NO layer located between the MP layer and a current collector; and/or cathodes include particles each composed of both NO and MP active materials. Methods are also disclosed.[French]
L'invention concerne des cellules de stockage d'énergie électrochimique qui comprennent des noyaux comportant des matériaux actifs de cathode à la fois de type oxyde de nickel (NO) et de type phosphate à base de métal (MP), le matériau actif MP étant prévu pour augmenter la résistance à l'emballement thermique. Dans certains modes de réalisation : les matériaux actifs NO et MP sont disposés sur des cathodes différentes ; les cathodes comprennent un mélange des matériaux actifs NO et MP ; un rapport pondéral du matériau actif MP au matériau ctif NO varie au sein d'une couche active de cathode, dans certains cas avec un pourcentage en poids de matériau actif MP augmentant dans une direction s'éloignant d'un collecteur de courant ; des cathodes comprennent une couche active de cathode comportant de multiples sous-couches comportant des mélanges uniformes différents de matériaux NO et MP ; des cathodes comprennent des couches de NO et de MP discrètes, certains modes de réalisation comportant la couche de NO située entre la couche de MP et un collecteur de courant ; et/ou des cathodes comprennent des particules composées chacune de matériaux actifs à la fois de NO et de MP. L'invention divulgue également des procédés.
