Abstract
(EN)
Provided herein are apparatus, systems, and methods of powering electric vehicles. A battery pack can be disposed in an electric vehicle to power the electric vehicle. The apparatus can include a battery cell. A battery cell can have a housing that defines a cavity. The battery cell can have a solid electrolyte. The electrolyte can be arranged within the cavity. The battery cell can have a cathode disposed within the cavity along a first side of the electrolyte. The battery cell can have a functional layer disposed within the cavity along a second side of the electrolyte. A first side of the functional layer can be in contact with a second side of the electrolyte. The functional layer can form an alloy with lithium material received via the electrolyte. The battery cell can have a scaffold layer disposed within the cavity along a second side of the functional layer.

L'invention concerne des appareils, des systèmes et des procédés d'alimentation de véhicules électriques. Un bloc-batterie peut être disposé dans un véhicule électrique pour alimenter le véhicule électrique. L'appareil peut comprendre une cellule de batterie. La cellule de batterie peut avoir un boîtier qui délimite une cavité. La cellule de batterie peut avoir un électrolyte solide. L'électrolyte peut être disposée dans la cavité. La cellule de batterie peut avoir une cathode disposée à l'intérieur de la cavité sur un premier côté de l'électrolyte. La cellule de batterie peut avoir une couche fonctionnelle disposée à l'intérieur de la cavité sur un second côté de l'électrolyte. Le premier côté de la couche fonctionnelle peut être en contact avec le second côté de l'électrolyte. La couche fonctionnelle peut former un alliage avec un matériau au lithium reçu par l'intermédiaire de l'électrolyte. La cellule de batterie peut avoir une couche d'échafaudage disposée à l'intérieur de la cavité sur le second côté de la couche fonctionnelle.
