Abstract
A metal-air battery has an anode in which the electrochemically active material is molybdenum. The molybdenum may be in the form of a bulk body of material or it may comprise a particulate material dispersed with or in another material. In some instances, the molybdenum may comprise a member of an alloy or mixture. Also disclosed is a modular battery system which may include the molybdenum-based anode material.
Claims19
A metal-air battery operating at ambient conditions comprising:
- an anode made of molybdenum;
- a cathode which is operative to reduce oxygen when the battery is operative to generate electrical power;
- and
- an aqueous electrolyte disposed in contact with said anode and said cathode.
A modular metal-air battery system comprising:
- a cathode assembly comprising a housing having a cathode disposed therein, said cathode being operative to reduce oxygen when the battery is operative to generate electrical power;
- an anode cartridge disposed therein having an anode comprising molybdenum, said molybdenum being oxidized when said battery is operative to generate electrical power, said anode cartridge being capable of reversibly engaging said cathode assembly so that in the use of said modular metal-air battery system, said anode cartridge may be replaced;
- and
- a body of an electrolyte disposed in at least one of said cathode assembly and said anode cartridge.
A metal-air battery operating at ambient conditions comprising a molybdenum anode as an electrochemically active metal which is oxidized when the battery is operative to generate electrical power, and a cathode which is operative to reduce oxygen when the battery is operative to generate electrical power.
