Title
(EN) ELECTRIC VEHICLE SOLID STATE BATTERY CELL
(FR) ÉLÉMENT DE BATTERIE À SOLIDE DE VÉHICULE ÉLECTRIQUE
Abstract
(EN)
A solid state battery cell can include a first polarity terminal, a second polarity terminal and a housing defining a cavity and functioning as a current collector for the first polarity terminal. The battery cell can include a membrane disposed in the cavity and dividing the cavity into a first portion and a second portion, an electrically conductive pin functioning as a current collector for the second polarity terminal, and an insulator electrically isolating the electrically conductive pin from the housing. A solid state anode material, including solid state anode particles, first solid state electrolyte particles and a first conductive additive, can be disposed in the first portion of the cavity. A solid state cathode material, including solid state cathode particles, second solid state electrolyte particles and a second conductive additive, can be disposed in the second portion of the cavity.

L'invention concerne un élément de batterie à solide pouvant comprendre une borne de première polarité, une borne de seconde polarité et un boîtier délimitant une cavité et servant de collecteur de courant pour la borne de première polarité. L'élément de batterie peut comprendre une membrane disposée dans la cavité et divisant la cavité en une première partie et une seconde partie, une broche électriquement conductrice servant de collecteur de courant pour la borne de seconde polarité, et un isolant isolant électriquement la broche électriquement conductrice du boîtier. Un matériau d'anode solide, comprenant des particules d'anode solide, des premières particules d'électrolyte solide et un premier additif conducteur, peut être disposé dans la première partie de la cavité. Un matériau de cathode solide, comprenant des particules de cathode solide, des secondes particules d'électrolyte solide et un second additif conducteur, peut être disposé dans la seconde partie de la cavité.
