Aluminium compound additives to reduce zinc corrosion in anodes of electrochemical cells.

摘要

In accordance with the present invention, an electrochemical cell is disclosed comprising a metal oxide cathode; an anode/electrolyte mixture which contains a zinc anode material and an aluminum compound additive as an source of aluminum ions (e.g., an aluminum salt). The anode/electrolyte mixture may also contain a source of sulfate ions (e.g., a metal sulfate). The anode/electrolyte mixture can also include a suitable carrier (e.g., gelling agent, buffer) for admixing the various components of the mixture.
