摘要： A RECHARAGEABLE ZINC CELL AND BATTERY, PREFERABLY A ZINCAIR CELL AND BATTERY, ARE DISCLOSED IN WHICH THE CELL COMPRISES (1) A CIRCULAR CASING HAVING A CIRCULAR RESERVOIR WITH ELECTROLYTE CONTAINED THEREIN; (2) A ROTATABLE ELECTRODE, HAVING AT LEAST ONE PLANAR ZINC SURFACE, ENCLOSED COAXIALLY IN THE RESERVOIR; (3) A STATIONARY PLANAR COUNTERELECTRODE SPACED FROM THE ROTATABLE ELECTRODE; (4) MEANS

FOR PREVENTING THE ELECTROCHEMICAL REACTION IN THE AXIAL AREA OF THE ZINC SURFACE; (5) WIPER MEANS DISPOSED BETWEEN THE ELECTRODES FOR LIGHTLY ABRADING THE ZINC SURFACE, AND (6) MEANS FOR AGITATING THE ELECTROLYTE TO MAINTAIN PARTICULATE MATTER IN SUSPENSION.
