Abstract
The battery includes an electrolyte activating a positive electrode and a negative electrode. The electrolyte includes a plurality of salts in a solvent, one or more passivation salts in the solvent, and one or more passivation additives in the solvent. At least one of the passivation salts forms a passivation layer on the negative electrode during discharge of the battery and includes both lithium and boron. At least one of the salts is an inorganic lithium salt that excludes boron. The solvent includes one or more organic solvents. At least one of the passivation additives forms a passivation layer on the negative electrode during discharge of the battery and is not a salt. The positive electrode has one or more positive active materials that each include a lithium transition-metal oxide and the negative electrodes includes a negative active material selected from a group consisting of lithium metal and graphite.
