Abstract: The present disclosure relates to alkaline electrochemical cells, such as metal-air cells, which comprise a gelled anode which may or may not include mercury, comprising an ionically conductive clay additive. The ionically conductive clay additive is modified to include halogen atoms to increase the negative charge density of the additive and improve its performance in the electrochemical cell.

Abstract: The present disclosure relates to alkaline electrochemical cells, such as metal-air cells, which comprise a gelled anode including an improved gelling agent. The gelling agent is a self-wetting, easy to disperse gelling agent that allows for even wet-up of the gelling agent during water intake. The even wet up allows the gelling agent to reach its full matrix potential and anode active material coating ability with provides for better diffusion characteristics. Additionally, the gelling agent has a high electrolyte tolerance and can withstand the solution pressure commonly associated with high pH systems.

Abstract: A metal-air electrochemical cell that includes spun mercury-amalgamated zinc powder particles is disclosed. The mercury-amalgamated zinc powder particles have advantageous physical properties that improve the performance characteristics of the cell including increasing the rate capability while decreasing the failure rate of the cell from buildup of hydrogen gas in the cell.
