Claims
- 1. A non-aqueous primary battery having
- (a) a light metal anode selected from the group consisting of lithium, magnesium, aluminum, beryllium, calcium, sodium, and potassium;
- (b) an electrolyte solution comprised of an organic solvent and a light inorganic salt dissolved therein;
- (c) a separator; and
- (d) a cathode consisting of silver chromate without binder or conductive additives.
- 2. The battery of claim 1 in which the light metal anode is lithium.
- 3. The battery of claim 1 in which the non-aqueous solvent is propylene carbonate.
- 4. The battery of claim 3 in which the light metal inorganic salt is lithium perchlorate and the concentration of the salt in the electrolytic solution is about 1 molar.
- 5. The battery of claim 3 wherein the light metal inorganic salt is lithium hexafluoroarsenate and the concentration of the salt in the electrolytic solution is about 1 molar.
- 6. The battery of claim 1 in which the light metal anode is lithium, and the electrolytic solution is propylene carbonate containing lithium perchlorate.
- 7. A method for preparing cathodes of metal chromates for use in high energy density, organic-electrolyte, electrochemical cells which consists essentially of the steps of compressing powdered metal chromate and uncured binder into cathode form at a pressure in the range 1500-5000 psi, and maintaining said cathodes at a temperature below about 25.degree. C. throughout the formation of the cathodes, wherein said metal chromate is selected from the group consisting of metal chromates, metal dichromates and metal basic chromates.
- 8. The method according to claim 7 wherein said cathode in final form contains up to 5 percent of uncured fluorinated hydrocarbon binder.
- 9. The method according to claim 7 wherein said chromate is basic mercuric chromate having the formula (HgO).sub.x (CrO.sub.3).sub.y wherein the mole ratio of x/y varies from about 1:1 to 1:0.22.
