    Abstract: 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 includes a solvent mixture and a lithium salt serving as a primary lithium ion conductor in the electrolyte to allow for lithium ion intercalation and deintercalation processes at the cathode and the anode during charging and discharging of the lithium ion battery cell. The solvent mixture includes a cyclic carbonate and one or more non-cyclic carbonates. The lithium salt is lithium bis(fluorosulfonyl)imide (LiFSI). The solvent mixture and LiFSI are configured to enhance the low temperature performance of the lithium ion battery cell at operating temperatures below 0° C.

    Abstract: The present disclosure relates generally to the field of batteries and battery modules. More specifically, the present disclosure relates to battery cells that may be used in vehicular contexts, as well as other energy storage/expending applications. An electrolyte solution includes at least one ester solvent and a plurality of additives. In particular, the plurality of additives includes a cyclic carbonate-based additive, a sultone-based additive, and either a borate-based additive or an imide-based additive. The presently disclosed electrolyte solutions enable the manufacture of battery cells having a wide operating temperature range (e.g., between approximately −30° C. and approximately 60° C.).
