Title (EN) RECHARGEABLE BATTERY STACKS
(FR) EMPILEMENTS DE BATTERIES RECHARGEABLES
Abstract:
(EN) High-capacity (i.e., a capacity of 50 mAh/gm or greater) and high-performance rechargeable batteries are provided that contain a rechargeable battery stack that includes a spalled material structure that includes a cathode material layer that is attached to a stressor material. The cathode material may include a single crystalline that is devoid of polymeric binders. The stressor material serves as a cathode current collector of the rechargeable battery stack.
(FR) L'invention concerne des batteries rechargeables à haute capacité (c'est-à-dire une capacité supérieure ou égale à 50 mAh/gm) et à haute performance qui contiennent un empilement de batteries rechargeables qui comprend une structure de matériau écaillé qui comprend une couche de matériau de cathode qui est fixée à un matériau de contrainte. Le matériau de cathode peut comprendre un monocristallin qui est dépourvu de liants polymères. Le matériau de contrainte sert de collecteur de courant de cathode de l'empilement de batteries rechargeables.
