Utility
Alkaline electrochemical cell with improved anode and separator components
22 Jun 20
An alkaline electrochemical cell includes a cathode, an anode which includes an anode active material, and a non-conductive separator disposed between the cathode and the anode, wherein from about 20% to about 50% by weight of the anode active material relative to a total amount of anode active material has a particle size of less than about 75 μm, and wherein the separator includes a unitary, cylindrical configuration having an open end, a side wall, and integrally formed closed end disposed distally to the open end.

Utility
Method of Manufacturing a Metal-air Cell
1 Apr 20
The invention includes a method of making a catalytic electrode for a metal-air cell in which a carbon-catalyst composite is produced by heating a manganese compound in the presence of a particulate carbon material to form manganese oxide catalyst on the surfaces of the particulate carbon, and then adding virgin particulate carbon material to the carbon-catalyst composite to produce a catalytic mixture that is formed into a catalytic layer.
