  • Ionically conductive clay additive for use in electrochemical cells
    Publication number: 20070122709
    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.

  • Electrochemical cells containing spun mercury-amalgamated zinc particles having improved physical characteristics
    Publication number: 20070048575
    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.
