Abstract
A novel battery is disclosed in which the cathode active material is an oxide having a perovskite or perovskite related structure and the general formula ABO.sub.3, wherein A is an element selected from Group IIA of the Periodic Table of the Elements and B is a non-noble transition metal selected from Group VIIB and VIII of the periodic Table of the Elements. The anode is a metal selected from cadmium, zinc, lead, lithium, sodium and potassium.
Claims13
An electrical energy storage device comprising:
- a. a container;
- b. an electrolyte in said container;
- c. a metal anode;
- and
- d. a cathode-active material, said cathode active material being an oxide of the general formula ABO.sub.3 and having perovskite structure, wherein A is selected from the group consisting of non-transition metals of Group IIA of the Periodic Table of the Elements and B is a non-noble transition metal selected from Groups VIIB and VIII of the Periodic Table of the Elements.
A battery comprising a container, an aqueous basic electrolyte, a metal anode selected from zinc, cadmium or lead and a cathode-active material selected from the perovskites CaMnO.sub.3, BaNiO.sub.3, SrCoO.sub.3 and SrFeO.sub.3.
A battery comprising a container, a non-aqueous electrolyte, a metal anode selected from lithium, potassium and sodium, and a cathode-active material selected from the perovskites CaMnO.sub.3, BaNiO.sub.3, SrCoO.sub.3 and SrFeO.sub.3.
