International Classification:
H01M 604
US Classification:
429206
Abstract:
A method for forming a gelled anode in which a powdered anode metal is mixed with means for maintaining a uniform mixture of the powdered metal and a gelling agent, the gelling agent is added, and the mixture is fed into an aqueous electrolyte in the cell whereupon a gel is formed in situ.

Assignee:
Duracell Inc. - Bethel CT
International Classification:
H01M 1052
US Classification:
429 57
Abstract:
An agent which absorbs hydrogen gas for electrochemical cells is made from an oxide of manganese and nickel, cobalt or iron. At temperatures above about 40. degree. C. , the oxide of manganese can be replaced by lead oxide. Hydrophobic binders can be added to the agent or the agent can be microencapsulated in water-impermeable but hydrogen-gas-permeable materials. The agent is preferably added to the cell in the form of small agglomerates or microcapsules.
