ELECTROLYTE SOLUTIONS FOR LITHIUM-ION BATTERY CELLS OPERATING OVER A WIDE TEMPERATURE RANGE

摘要

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.).
