HEAT MANAGEMENT IN ALUMINUM AIR BATTERIES - SOURCES OF HEAT

One of the problems with the aluminium/air battery is the generation o f heat, during both idle and discharge periods. The main sources of he at are: (i) corrosion of the aluminium anode during the idle period; ( ii) inefficient, or less efficient, dissolution of anode during discha rge; (iii) Joule heat during discharge, and (iv) non-uniform mass tran sfer during both discharge and idle periods. These components of heat act in a cumulative way because they are all interconnected. This pape r addresses the basic reasons for the origin of these sources of heat. Suitable and practical remedial measures for the effective removal of such heat in the aluminium/air battery are suggested.
