Abstract
(EN) Disclosed is a solid lithium cell formed by stacking an etched copper substrate (15), a layer of graphite (14), an electrolyte (12) and a layer of nickel, manganese and cobalt oxides (11), the electrolyte (12) being in contact with the graphite layer (14) and the layer of nickel, manganese and cobalt oxides (11), the copper substrate (15) forming the anode of the cell, the layer of nickel, manganese and cobalt oxides (11) forming the cathode of the cell, the electrolyte (12) being a solid lithium-based electrolyte, and the graphite layer (15) having a first solid electrolyte interface (16) produced during a pre-lithiation with a liquid lithium-based electrolyte and a second solid electrolyte interface (17) produced during a pre-lithiation with the solid lithium-based electrolyte.
(FR) Cellule au lithium solide formée par empilement d'un substrat de cuivre gravé (15), d'une couche de graphite (14), d'un électrolyte (12) et d'une couche d'oxydes de nickel, manganèse et cobalt (11), l'électrolyte (12) étant en contact avec la couche de graphite (14) et la couche d'oxydes de nickel, manganèse et cobalt (11), le substrat de cuivre (15) formant l'anode de la cellule, la couche d'oxydes de nickel, manganèse et cobalt (11) formant la cathode de la cellule, l'électrolyte (12) étant un électrolyte à base de lithium solide, et la couche de graphite (15) présentant une première interface d'électrolyte solide (16) réalisée pendant une pré-lithiation avec un électrolyte à base de lithium liquide et une deuxième interface d'électrolyte solide (17) réalisée pendant une pré-lithiation avec l'électrolyte à base de lithium solide.
