Abstract

Aluminum-air battery units and stacks are provided with frames configured to mechanically support the anode of each unit, within a housing configured to support the frame and the air cathode(s) mechanically, sealably hold the electrolyte within the housing and in fluid communication with openings in the housing—forming one or two sided electrochemical cell in each unit. The frame comprises a protective strap configured to protect edges of the rectangular anode against corrosion by the electrolyte during operation, and also an external trapezoid shape that is configured to press the protective strap against the edges of the rectangular anode upon insertion of the frame with the anode into the housing. Various embodiments comprise, spacers between the anode and cathodes and grids supporting airways to the cathodes. In disclosed configurations, anode may be replaced after electrolyte evacuation while maintaining the stack sealed and quickly ready for renewed operation.
