Abstract
The invention encompasses battery electrolytes and batteries. In one aspect, the invention encompasses a battery electrolyte which includes the lithium salts, LiN(CF.sub.3 SO.sub.2).sub.2, and LiCF.sub.3 SO.sub.3 in a solvent blend comprising ethylene carbonate, propylene carbonate, and 1,2-dimethoxyethane. In another aspect, the invention encompasses a battery. The battery includes a first electrode, a second electrode, and an electrolyte between the first and second electrodes. The electrolyte comprises these lithium salts in a solvent blend comprising ethylene carbonate, propylene carbonate, and 1,2-dimethoxyethane. In yet another aspect, the invention encompasses another embodiment of a battery. The battery includes a cathode comprising at least one of MnO.sub.2 and (CF).sub.x, and an anode comprising lithium. The battery further includes a non-aqueous electrolyte between the cathode and the anode. The non-aqueous electrolyte comprises the lithium salts in a solvent blend comprising ethylene carbonate, propylene carbonate, and 1,2-dimethoxyethane. The lithium salts comprise a mixture of LiN(CF.sub.3 SO.sub.2).sub.2, and LiCF.sub.3 SO.sub.3.
