Title (EN) AMORPHOUS LIF AS AN ARTIFICIAL SEI LAYER FOR LITHIUM BATTERIES
(FR) LIF AMORPHE EN TANT QUE COUCHE SEI ARTIFICIELLE POUR BATTERIES AU LITHIUM
Abstract:
(EN) A battery, in particular a Lithium-ion battery, includes a cathode, anode, and electrolyte. The cathode includes a first substrate with solid cathode material, and a first amorphous coating above the first substrate that acts as a first artificial solid-electrolyte interface ("SEI") layer for the first substrate. The anode includes a second substrate with solid anode material, and a second amorphous coating above the second substrate that acts as a second artificial SEI layer for the second substrate. The electrolyte is disposed directly between the first and second amorphous coatings. A method of producing battery includes using low temperature atomic layer deposition processes to deposit material on first and second substrates, respectively, to form first and second amorphous coatings. The method further includes arranging an electrolyte directly between the first and second amorphous coatings in order to form a battery.
(FR) L'invention concerne une batterie, en particulier une batterie au lithium-ion, comprenant une cathode, une anode et un électrolyte. La cathode comprend un premier substrat avec un matériau de cathode solide, et un premier revêtement amorphe au-dessus du premier substrat qui agit comme une première couche ("SEI") d'interface solide-électrolyte artificielle pour le premier substrat. L'anode comprend un second substrat avec un matériau d'anode solide, et un second revêtement amorphe au-dessus du second substrat qui agit comme une seconde couche SEI artificielle pour le second substrat. L'électrolyte est disposé directement entre les premier et second revêtements amorphes. Un procédé de production de batterie comprend l'utilisation de procédés de dépôt de couche atomique à basse température pour déposer un matériau sur des premier et second substrats, respectivement, pour former des premier et second revêtements amorphes. Le procédé comprend en outre l'agencement d'un électrolyte directement entre les premier et second revêtements amorphes afin de former une batterie.
