Electrolyte solutions including additives or combinations of additives that provide low temperature performance and high temperature stability in lithium ion battery cells.

Electrolyte formulations for lithium ion batteries

The present disclosure relates to micro-hybrid battery modules that include at least one battery cell having a titanate-based oxide anode active material with spinel structure and a high voltage spinel (LiMnMO) cathode active material. The battery module may be configured to couple to an energy storage unit to enable the module to be used in start-stop applications.

Micro-hybrid battery module for a vehicle

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.

Electrolytes for low impedance, wide operating temperature range lithium-ion battery module

The performance of a lithium ion-cell where the cathode is a layered-layered lithium rich cathode material xLiMO(1-x)LiMNO, M being a transition metal selected from the group consisting of Co, Ni, or Mn, is improved by coating the surface of the cathode with a sulfonyl-containing compound, such as poly(1,4-phenylene ether-ether-sulfone), inhibits the reactivity of the electrolyte with the oxidized electrode surface while allowing lithium ion conduction.

Polysulfone coating for high voltage lithium-ion cells

Electrolyte solutions including combinations of high dielectric and low viscosity solvents. These solvent combinations provide low temperature performance and high temperature stability in lithium ion battery cells.
