Patent number: 11670759Abstract: 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.Type: GrantFiled: July 14, 2021Date of Patent: June 6, 2023Assignee: The Government of the United States of America, as represented by the Secretary of the NavyInventors: Brandon J.

Patent number: 11296373Abstract: 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.Type: GrantFiled: October 25, 2018Date of Patent: April 5, 2022Assignee: The Government of the United States of America, as represented by the Secretary of the NavyInventors: Joseph F. Parker, Jeffrey W. Long, Debra R. Rolison, Christopher N. Chervin
