Biological Battery Reactor System in manufacturing Metal Oxide, generating electricity, and fixing CO2

A method of using battery electrochemical reactions to produce metal oxide material with nano structures can be through batch or continuous battery systems and including:

• a metal air battery set up, including:
• a metal anode electrode as electron donor, and
• a cathode using oxygen or air as electron acceptor, and
• an electrolyte solution that contacts anode and cathode directly, and
• an external circuit connect the anode and cathode through wire, and
• energy transfer or storage devices or both, for example resistors or capacitor, and
• filter, wash, and dry the precipitation from the metal air battery, and
• treatment to form desired structured metal oxide compounds.

A biological battery reactor system is in manufacturing of Zinc oxide, generating electricity and other compounds, wherein the system can be batch, semi-batch or continuous flow system and including:

• an influence vessel or tank, configured to retain therein influence medium, and including:
• an electrolyte, and
• a biological medium, and
• a biological battery reactor, configured to have metal air redox reaction to form metal oxide, generate electricity and other compounds, and including:
• a cathode electrode, and
• an anode electrode, and
• an electrolyte, and
• a biological medium, and
• electricity collectors and connectors to the external circuit, and
• pipelines connect the influence medium in the influence vessel and the medium in the biological battery reactor, and
• a discharge or recycle of effluent products for different post treatment, and
• a gas supply when it is needed to provide constant, individually controlled, or precise amount of CO2 or other gases for utilizing by microorganisms or the system.
