ELECTROLYTES FOR LOW IMPEDANCE, WIDE OPERATING TEMPERATURE RANGE LITHIUM-ION BATTERY MODULE |
摘要 |
A lithium ion battery cell includes a housing, a cathode disposed within the housing, wherein the cathode comprises a cathode active material, an anode disposed within the housing, wherein the anode comprises an anode active material, and an electrolyte disposed within the housing and in contact with the cathode and anode. The electrolyte consists essentially of a solvent mixture, a lithium salt in a concentration ranging from approximately 1.0 molar (M) to approximately 1.6 M, and an additive mixture. The solvent mixture includes a cyclic carbonate, an non-cyclic carbonate, and a linear ester. The additive mixture consists essentially of lithium difluoro(oxalato)borate (LiDFOB) in an amount ranging from approximately 0.5 wt % to approximately 2.0 wt % based on the weight of the electrolyte, and vinylene carbonate (VC) in an amount ranging from approximately 0.5 wt % to approximately 2.0 wt % based on the weight of the electrolyte. |
