A dual porosity cathode for a lithium-air battery made from porous nanographene sponge molded to form a multitude of pores embedded in a polymer layer. The first level of porosity is the interior surface area of the molded pores. The second level of porosity is the interior surface area within the micropores within the porous nanographene sponge material. The dual porosity cathode is useful for a lithium-air battery because of the greatly increased cathode surface area created by the micropores and the very small localized quantities of LiOthat form in the micropores from the reaction between Liand oxygen.

Dual porosity cathode for lithium-air battery

A battery with many cavities that form tiny reaction zones having voids. During charging, lithium metal forms in each cavity on the anode current collector. The formation of lithium metal in each of the many thousands of small cavities that are isolated from each other prevents the buildup of significant quantities of lithium metal in one location. The combination of tiny reaction zones and voids allows lithium metal to form without stressing the structure of the battery cell.

A method of fabricating a porous wafer battery comprises the steps of providing a silicon wafer comprising a plurality of pores; applying a first metallization process; applying a passivation process; applying solder balls, aligning the silicon wafer with a substance, and applying a solder reflow process. A method using a porous wafer battery comprises the steps of connecting the porous wafer battery to a plurality of sensors, a plurality of switches, and a battery management system; monitoring temperature, resistance, or current; and electrically disconnecting a non-properly functioning pore.

Method of fabricating and method of using porous wafer battery

A battery using porous polymer materials with tapered or cone-shaped metalized pores. The types of batteries include, but are not limited to, Li&#x2014;CoO2, Li&#x2014;Mn2O4, Li&#x2014;FePO4, Li&#x2014;S, Li&#x2014;O2, and other lithium cathode chemistries. The tapered metalized pores contain lithium metal in small reaction zones in the anode and cathode in a flexible structure. The form factor of such assembly would be very thin. Because of the thin form factor these electrodes would be suitable for batteries that require high power density, such certain electrical vehicles, power tools, and wearable devices.

Porous polymer lithium anode

Viruses, including corona viruses such as COVID-19, are often present in the mouth or nose of a person before they infect the body. The disclosed electrochemical device destroys or denatures viruses in the mouth or nose rendering the viruses ineffective to cause infection by applying a low voltage potential to the mucus. The device has a potentiostat powered by a small battery embedded in a plastic frame that fits in a person's mouth. The device has electrodes to contact the mucus of the mouth or nose. The mucus serves as electrolyte, conducting ions as well as viruses with their protein 'skin' towards the electrode. The viruses are adsorbed onto the metal probes where the electrical current denatures the protein skin of the virus rendering the virus ineffective to cause infection.

Electrochemical device for virus detection and treatment

The present invention disclosed herein is directed to nitric acid regeneration fuel cell systems that comprise: an anode; a cathode confronting and spaced apart from the anode; an anolyte flowstream configured to flowingly contact the anode, wherein the anolyte flowstream includes a fuel, preferably methanol, for reacting at the anode; a catholyte flowstream configured to flowingly contact the cathode, wherein the catholyte flowstream includes nitric acid for reacting at the cathode to thereby yield cathode reaction products that include nitric oxide and water in a catholyte effluent flowstream; and a hydrogen peroxide flowstream configured to contact and react hydrogen peroxide with the nitric oxide of the catholyte effluent flowstream at a hydrogen peroxide oxidation zone to thereby yield a regenerated nitric acid flowstream. The regenerated nitric acid flowstream is preferably reused in the catholyte flowstream.
