Title (EN) NON-FLAMMABLE ELECTROLYTE CONTAINING LIQUEFIED GAS AND LITHIUM SECONDARY BATTERIES CONTAINING SAME
(FR) ÉLECTROLYTE ININFLAMMABLE CONTENANT UN GAZ LIQUÉFIE ET BATTERIES SECONDAIRES AU LITHIUM CONTENANT CE DERNIER
Abstract:
(EN) A rechargeable lithium cell comprising a cathode, an anode, an optional ion-permeable membrane disposed between the anode and the cathode, a non-flammable salt-retained liquefied gas electrolyte in contact with the cathode and the anode, wherein the electrolyte contains a lithium salt dissolved in or mixed with a liquefied gas solvent having a lithium salt concentration greater than 1.0 M so that the electrolyte exhibits a vapor pressure less than 1 kPa when measured at 20°C, a vapor pressure less than 60% of the vapor pressure of the liquefied gas solvent alone, a flash point at least 20 degrees Celsius higher than a flash point of the liquefied gas solvent alone, a flash point higher than 150°C, or no flash point, wherein the liquefied gas solvent is selected from methane, fluoromethane, difluoromethane, chloromethane, dichloromethane, ethane, fluoroethane, difluoroethane, tetrafluoroethane, chloroethane, dichloroethane, tetrachloroethane, propane, fluoropropane, chloropropane, ethylene, fluoroethylene, chloroethylene, or a combination thereof.
(FR) L'invention concerne une pile au lithium rechargeable comprenant une cathode, une anode, une membrane perméable aux ions facultative disposée entre l'anode et la cathode, un électrolyte de gaz liquéfié à rétention de sel ininflammable en contact avec la cathode et l'anode, l'électrolyte contenant un sel de lithium dissous dans ou mélangé à un solvant de gaz liquéfié présentant une concentration en sel de lithium supérieure à 1,0 M de sorte que l'électrolyte présente une pression de vapeur inférieure à 1 kPa lorsqu'elle est mesurée à 20 °C, une pression de vapeur inférieure à 60 % de la pression de vapeur du solvant de gaz liquéfié seul, un point d'éclair supérieur d'au moins 20 degrés Celsius à un point d'éclair du solvant de gaz liquéfié seul, un point d'éclair supérieur à 150 °C ou aucun point d'éclair, le solvant gazeux liquéfié étant choisi parmi le méthane, le fluorométhane, le difluorométhane, le chlorométhane, le dichlorométhane, l'éthane, le fluoroéthane, le difluoroéthane, le tétrafluoroéthane, le chloroéthane, le dichloroéthane, le tétrachloroéthane, le propane, le fluoropropane, le chloropropane, l'éthylène, le fluoroéthylène, le chloroéthylène ou une combinaison de ces derniers.
