Title (EN) NON-COMBUSTIBLE LITHIUM ION BATTERY ELECTROLYTE AND BATTERY THEREOF
(FR) ÉLECTROLYTE DE BATTERIE AU LITHIUM-ION NON COMBUSTIBLE ET BATTERIE ASSOCIÉE
(ZH) 不燃型锂离子电池电解液及其电池
Abstract:
(EN) Disclosed in the invention are a non-combustible lithium ion battery electrolyte and a non-combustible lithium ion battery using the electrolyte. The non-combustible lithium ion battery electrolyte comprises: organic solvent and lithium salt. The organic solvent comprises a carbonate compound. The organic solvent comprise a monofluorocarbonate compound and/or a trifluorocarbonate compound. According to the non-combustible lithium ion battery electrolyte of the invention, the cycle stability of the obtained battery can be maintained only through the composition of the organic solvent and the lithium salt, without adding other additives. Meanwhile, shortcomings can be overcome that existing lithium ion battery electrolytes are flammable and explosive under high temperature environments. The invention also discloses a lithium ion battery comprising the non-combustible lithium ion battery electrolyte.
(FR) L'invention concerne un électrolyte de batterie au lithium-ion non combustible et une batterie au lithium-ion non combustible utilisant l'électrolyte. L'électrolyte de batterie au lithium-ion non combustible comprend : un solvant organique et un sel de lithium. Le solvant organique comprend un composé carbonate. Le solvant organique comprend un composé monofluorocarbonate et/ou un composé trifluorocarbonate. Selon l'électrolyte de batterie au lithium-ion non combustible de l'invention, la stabilité de cycle de la batterie obtenue peut être maintenue uniquement à travers la composition du solvant organique et du sel de lithium, sans ajout d'autres additifs. En même temps, des défaillances dues au fait que les électrolytes de batterie au lithium-ion existants sont inflammables et explosifs dans des environnements à haute température, peuvent être surmontées. L'invention concerne également une batterie au lithium-ion comprenant l'électrolyte de batterie au lithium-ion non combustible.
(ZH) 本发明公开了一种不燃型锂离子电池电解液及应用了该电解液的不燃型锂离子电池。所述不燃型锂离子电池电解液,包括:有机溶剂和锂盐;所述有机溶剂包括碳酸酯类化合物;所述有机溶剂包括一氟代碳酸酯类化合物和/或三氟代碳酸酯类化合物。该不燃型锂离子电池电解液在不增加其他添加剂的情况下,仅由有机溶剂和锂盐组成即能保持所得电池的循环稳定性,又能克服现有锂离子电池电解液高温环境易燃易爆的缺点。本发明还公开了包含不燃型锂离子电池电解液的锂离子电池。
