Title (EN) LITHIUM BATTERY AND USE OF TRIPHENYLPHOSPHINE OXIDE AS AN ELECTROLYTE ADDITIVE THEREIN
(FR) BATTERIE AU LITHIUM DANS LAQUELLE EST UTILISÉ DE L'OXYDE DE TRIPHÉNYLPHOSPHINE COMME ADDITIF D'ÉLECTROLYTE
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 manganese cobalt oxide (NMC), and an electrolyte separating anode and cathode, wherein the electrolyte comprises a solvent or solvent mixture and lithium hexafluorophosphate, wherein the electrolyte further comprises triphenylphosphine oxide. Moreover, the present invention further relates to the use of triphenylphosphine oxide as additive in the 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-cobalt (NMC), 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 de l'oxyde de triphénylphosphine. De plus, la présente invention concerne en outre l'utilisation d'oxyde de triphénylphosphine comme additif dans la batterie au lithium afin d'améliorer une caractéristique choisie dans le groupe constitué par la capacité réversible, l'efficacité coulombique, la stabilité cyclique et leurs combinaisons.
