  • Patent number: 11296373
    Abstract: A zinc-air battery having: a cathode, an anode, an electrolyte, a separator between the anode and the cathode, and a housing. The cathode includes: a cathode current collector and a composite having a porous carbon material, a porous cryptomelane-type MnOx material, a porous NiyFe1-yOx material, and a binder. The anode includes: a continuous network having metallic zinc and having metallic zinc bridges connecting metallic zinc particle cores and a continuous network of void space interpenetrating the zinc network. The electrolyte fills the void space in the anode, is in contact with the cathode, and permeates the composite without completely filling or obstructing a majority of the pores. The housing encloses the anode, the cathode, and the separator and exposes the composite to ambient air.

  • Publication number: 20210344001
    Abstract: Disclosed are methods of making porous zinc electrodes. Taken together, the steps are: forming a mixture of water, a soluble compound that increases the viscosity of the mixture, an insoluble porogen, and metallic zinc powder; placing the mixture in a mold to form a sponge; optionally drying the sponge; placing the sponge in a metal mesh positioned to allow air flow through substantially all the openings in the mesh; heating the sponge in an inert atmosphere at a peak temperature of 200 to 420° C. to fuse the zinc particles to each other to form a sintered sponge; and heating the sintered sponge in an oxygen-containing atmosphere at a peak temperature of 420 to 700° C. to form ZnO on the surfaces of the sintered sponge. The heating steps burn out the porogen.

  • Publication number: 20190083953
    Abstract: A high-surface-area, highly porous manganese oxide (MnOx) in the form of xerogel or aerogel monoliths or powders comprising a manganese oxide nanoarchitecture comprising an interior surface area >200 m2 g?1, wherein the MnOx gel has a void structure comprising pores that are sized from 2-150 nm, and wherein the manganese oxide nanoarchitecture removes toxic gas from a toxic gas and air mixture at room temperature via an oxidative mechanism that converts the toxic gas to an innocuous adsorbed substance. These high-surface-area, ultraporous manganese oxide (MnOx) xerogels and aerogels exhibit outstanding filtration performance for multiple, chemically distinct toxic gases, including ammonia, sulfur dioxide and hydrogen sulfide. These MnOx materials use multiple mechanisms for small molecule capture/catalysis including molecular sieving and oxidative decomposition, and function in a wide range of humidity conditions.
