Abstract
An active primary battery containing a lithium anode; an aprotic organic electrolyte; a separator; and a cathode made of silver (II) oxide, mercuric oxide, or a mixture of silver (II) oxide and mercuric oxide is described. The battery exhibits high open circuit and operating voltage under a wide range of current densities. The open circuit voltage of a lithium-silver (II) oxide battery of the present invention is almost double that obtained in a zinc-silver (II) oxide battery. The packaged capacity density, in amp-hrs/cc, is about twice that obtained in a lithium-manganese dioxide battery or a lithium-iodine battery. The packaged energy density, in watt-hours/cc, is also about twice that obtained in a zinc-silver (II) oxide battery, a lithium-manganese dioxide battery, and a lithium-iodine battery.
