A battery includes a negative electrode comprising metallic lithium (Li) in conjunction with lithium chlorate (LIClO/sub 3/) electrolyte. Lithium perchlorate (LIClO/sub 4/) may also be used as the electrolyte. Lithium chloride (LiCl) and lithium oxide (Li/sub 2/O), individually or together, may also be utilized with lithium chlorate or lithium perchlorate in forming the electrolyte. A positive electrode comprises a metal, such as nickel. In one form , a sheet of lithium metal is sandwiched between two sheets of nickel comprising a negative electrode, one nickel sheet being perforated to permit contact between the lithium sheet and a lithium chlorate electrolyte contained within an insulative member, the other electrode comprising a film of metallic nickel disposed upon the insulative member and in contact with the electrolyte; alternatively, a film or sheet of lithium metal may be disposed upon the insulator as a negative electrode. An additional form includes a ceramic housing comprising a solid ionic conductor and having an interior chamber containing sodium (Na) or lithium as a negative electrode; a liquid electrolyte is disposed within a recess formed by the exterior walls of the housing and a positive electrode in the form of a layer of metallic nickel disposed around the exterior walls of the housing , the electrolyte being in electrical contact with the respective electrodes. A pocket cell form comprises a liquid electrolyte disposed within a recess of a block with the negative electrode inside the recess and the positive electrode in the form of a screen at the mouth of the recess.
