Title (EN) LITHIUM SECONDARY BATTERY CONTAINING NON-FLAMMABLE ELECTROLYTE AND MANUFACTURING METHOD
(FR) BATTERIE RECHARGEABLE AU LITHIUM CONTENANT UN ÉLECTROLYTE NON INFLAMMABLE ET PROCÉDÉ DE FABRICATION
Abstract:
(EN) A rechargeable lithium cell comprising a cathode, an anode, a non-flammable electrolyte, wherein the electrolyte contains a lithium salt dissolved in a liquid solvent having a lithium salt concentration from 0.01 M to 10 M so that the electrolyte exhibits a vapor pressure less than 0.01 kPa when measured at 20°C, a vapor pressure less than 60% of the vapor pressure of the liquid solvent alone, a flash point at least 20 degrees Celsius higher than a flash point of the liquid solvent alone, a flash point higher than 200°C, or no flash point, wherein the liquid solvent contains a cooking oil selected from palm oil, palm olein, coconut oil, corn oil, soybean oil, cottonseed oil, peanut oil, sunflower oil, canola oil, rice bran oil, olive oil, sesame oil, safflower oil, avocado oil, flaxseed oil, grapeseed oil, walnut oil, almond oil, lard, or a combination thereof.
(FR) La présente invention concerne une pile au lithium rechargeable qui comprend une cathode, une anode, un électrolyte non inflammable, l'électrolyte contenant un sel de lithium dissous dans un solvant liquide ayant une concentration en sel de lithium comprise entre 0,01 M et 10 M de telle sorte que l'électrolyte présente une pression de vapeur inférieure à 0,01 kPa lorsqu'elle est mesurée à 20 °C, une pression de vapeur inférieure à 60 % de la pression de vapeur du solvant liquide seul, un point d'éclair d'au moins 20 degrés Celsius supérieur à un point d'éclair du solvant liquide seul, un point d'éclair supérieur à 200 °C, ou aucun point d'éclair, le solvant liquide contenant une huile de cuisson choisie parmi l'huile de palme, l'oléine de palme, l'huile de coco, l'huile de maïs, l'huile de soja, l'huile de coton, l'huile d'arachide, l'huile de tournesol, l'huile de colza, l'huile de son de riz, l'huile d'olive, l'huile de sésame, l'huile de carthame, l'huile d'avocat, l'huile de lin, l'huile de pépins de raisin, l'huile de noix, l'huile d'amande, le lard ou une combinaison de ces derniers.
