Abstract

The present invention relates generally to lithium batteries, and more specifically, to electrolyte compositions within lithium batteries. Some aspects of the invention are related to an electrolyte for a lithium battery. In some embodiments, the electrolyte comprises a lithium salt, an organic solvent, and an aromatic hydrocarbon solvent that is different from the organic solvent. The aromatic hydrocarbon solvent may have limited solubility in the organic solvent and/or a limited solubility for lithium salt, e.g., such that the aromatic hydrocarbon solvent is capable of inducing phase separation of the electrolyte when present in a certain amount. In one set of embodiments, an electrolyte comprising one or more aromatic hydrocarbon may lead to an enhanced battery cycle life, reduced rate of electrolyte degradation, and improved low temperature performance. The subject matter disclosed herein involves, in some cases, the use of the electrolyte in a lithium battery.
