"solvent maintain conductivity wide range temperatures, varying from –60 to 55 degrees Celsius.... Adding lithium perchlorate to electrolyte strengthens different chemicals in electrolyte interact with each other and reduces amount of energy required, making it easier for electrolyte to work at lower temperatures... diluted high concentration sulfolane-based electrolyte with lithium perchlorate additive realizes wide-temperature application in high voltage cells... high energy density lithium batteries"
