Abstract : The general object of this invention is to provide overcharge protection for rechargeable lithium-organic electrolyte batteries. A further object is to prevent the undesireable oxidation of organic solvents during the overcharge of the rechargeable lithium-organic electrolyte batteries. It has now been found that the aforementioned objects can be attained by including lithium bromide in the electrolyte to provide overcharge protection during the overcharging of rechargeable lithium-organic electrolyte cells. More particularly, it has been found that during overcharging, lithium bromide will be oxidized at lower potentials than the organic solvent and thereby provide overcharge protection and prevent the undesireable oxidation of organic solvents.
