Abstract
In an embodiment, an electrolyte includes a lithium salt and a cosolvent, where the cosolvent comprises a cyclic carbonate-containing solvent and a linear carbonate-containing solvent. In an embodiment, a battery includes an anode, a cathode, an electrolyte and a separator. The anode includes an anode current collector and an anode active layer. The anode active layer comprises a lithiated silicon oxide or a combination of lithiated silicon oxide and carbon present in an amount of 20 wt % or greater, based on a total weight of the anode active layer. The cathode includes a cathode current collector and a cathode active layer. The electrolyte includes a lithium salt and a cosolvent that includes a cyclic carbonate-containing solvent and a linear carbonate-containing solvent.
