Abstract
An air cathode battery is provided that uses a zinc slurry anode with carbon additives. The battery is made from an air cathode and a zinc slurry anode. The zinc slurry anode includes zinc particles, an alkaline electrolyte, with a complexing agent and carbon additives in the alkaline electrolyte. A water permeable ion-exchange membrane and electrolyte chamber separate the zinc slurry from the air cathode. The carbon additives may, for example, be graphite, carbon fiber, carbon black, or carbon nanoparticles. The proportion of carbon additives to zinc is in the range of 2.5 to 10% by weight. The proportion of alkaline electrolyte in the zinc slurry is in the range of 50 to 80% by volume.
