Air Cathode Battery Using Zinc Slurry Anode with Carbon Additive

An air cathode battery using a rechargeable zinc slurry anode, the battery comprising:

• an air cathode;
• a zinc slurry anode system comprising:
• zinc slurry comprising zinc particles, an alkaline electrolyte, a complexing agent, and carbon additives in the alkaline electrolyte;
• a slurry feed reservoir;
• a slurry collection reservoir;
• an anode current collector with a rechargeable active area adjacent to the air cathode, the active area accepting a fresh zinc slurry in a charged state from the slurry feed reservoir and providing a spent zinc slurry in a discharged state to the slurry collection reservoir;
• an electrolyte chamber, comprising an alkaline electrolyte, adjacent the air cathode;
• and,
• a water permeable ion-exchange membrane (IEM) interposed between the electrolyte chamber air cathode and the zinc slurry anode.
