Abstract
Abstract A RECHARGEABLE ELECTROCHEMICAL CURRENT GENERATOR WITH TWO ELECTRODES A OPPOSITE POLARITIES, HAVING GENERALLY PLANAR CONFRONTING WORKING SURFACES IMMERSED IN AN ELECTROLYTE IN WHICH THE ACTIVE MATERIAL (E.G. ZINC) OF THE NEGATIVE ELECTRODE IS SOLUBLE, IS CHARGED WITH CONTINUOUS DISPLACEMENT OF THE NEGATIVE ELECTRODE IN THE IN THE PLANE OF ITS WORKING SURFACE. SUCH AS ROTATION ABOUT AN AXIS, TO PREVENT THE SHORT-CIRCUITING OF THE SYSTEM BY THE GROWTH OF DENDRITIC FORMATIONS FROM THE NEGATIVE ELECTRODE TO THE POSITIVE COUNTERELECTRODE. A STATIONARY WIPER MAY BE HELD AGAINST THE WORKING SURFACE OF THE NEGATIVE ELECTRODE DURING ITS ROTATION TO HELP SMOOTH ITS ACTIVE LAYER.
