METHOD FOR PRODUCING IRON-PLATE ACTIVE MATERIAL FOR ALKALI CELL Russian patent published in 2003 - IPC

FIELD: electrical engineering; chemical power supplies; nickel-iron cells. SUBSTANCE: method for producing iron- plate active material by mixing active substance with activating dopes involves use of active material of spent nickel-iron cells for the purpose which is washed off carbonates and alkali followed by drying, whereupon activating dopes are introduced in following proportion relative to iron, mass percent: nickel sulfate, 0.05-0.15; commercial sulfur, 0.05-0.2; pure ferric oxides, 15-30; after that 1-3 mass percent of graphite is introduced in mixture obtained depending on its amount. EFFECT: reduced time of raising nickel-iron cell capacity when placing it in operation. 1 cl
