ELECTRODE FOR ALKALI STORAGE BATTERY AND METHOD FOR ITS MANUFACTURING Russian patent published in 2000 - IPC

FIELD: electrical engineering, in particular, manufacturing of alkali storage batteries. SUBSTANCE: current-conducting substrate is designed as three-ply nickel foil. Porosity of central ply is within range of 5-25%, its height is within range of 30-60 mu. Porosity of side plies is within range of 60-80 %; their height is within range of 70-50 mu. Current pick-up is provided by pressing cur-conducting substrate to achieve minimal porosity. The method for electrode production involves rolling and baking central ply in reducing atmosphere, shaping surface plies by means of deposition of nickel pulp onto both sides of central ply and their baking in reducing atmosphere, adding active material into cur-conducting substrate by means of chemical or electrochemical methods. EFFECT: improved specific electric characteristics of electrode. 2 dwg
