Title
(EN) LITHIUM BATTERY AND USE OF A UREA-BASED ADDITIVE AS AN ELECTROLYTE ADDITIVE CONTAINED THEREIN
(FR) BATTERIE AU LITHIUM ET UTILISATION D'UN ADDITIF À BASE D'URÉE EN TANT QU'ADDITIF D'ÉLECTROLYTE CONTENU EN SON SEIN
Abstract
(EN)
The present invention relates to a lithium battery comprising an anode comprising an active anode material, a cathode comprising an active cathode material comprising lithium nickel cobalt manganese oxide (NCM), and an electrolyte separating anode and cathode, wherein the electrolyte comprises a solvent or solvent mixture and lithium hexafluorophosphate, wherein the electrolyte further comprises a urea-based electrolyte additive. Moreover, the present invention further relates to the use of a specific urea- based electrolyte additive in a lithium battery for enhancing one characteristic selected from the group consisting of reversible capacity, Coulombic efficiency, cyclic stability and combinations thereof.
(FR)
La présente invention concerne une batterie au lithium comprenant une anode comprenant un matériau d'anode actif, une cathode comprenant un matériau de cathode actif comprenant de l'oxyde de lithium-nickel-manganèse (NCM), et un électrolyte séparant l'anode et la cathode, l'électrolyte comprenant un solvant ou un mélange de solvants et de l'hexafluorophosphate de lithium, l'électrolyte comprenant en outre un additif d'électrolyte à base d'urée. De plus, la présente invention concerne en outre l'utilisation d'un additif d'électrolyte spécifique à base d'urée dans une batterie au lithium pour améliorer une caractéristique choisie dans le groupe constitué par la capacité réversible, le rendement coulombien, la stabilité cyclique et des combinaisons associées.
