Alkaline accumulator battery - has cells with thin sheet steel walls, provided with depressions or porous sintered nickel coating

摘要

In alkaline accumulator battery comprising numerous individual cells arranged one behind the other, the cell walls (a) are of flat, deep drawable sheet steel, opt. Ni plated (b) have thickness of razor blade (c) serve as support of the active materials (I) (d) are provided with numerous depressions and/or highly porous sintered Ni layers to receive (I) (e) are bonded tightly and securely with each other by frame of plastics material surrounding them. (I) are Ni, Cd, or Fe. Depressions are filled on both faces with (I) of differing polarity to form bipolar plates. Plates, after incorporation of (I), are covered with highly porous plastics film and bonded together. An open pored, highly elastic layer of a plastics material is arranged between the plates to press (I). (I) are in tablet form and are fixed in the depressions with adhesive having good electrical conductivity. Flexible tubes are arranged in surrounding frame for evacuating cells then filling them with electrolyte. Cell walls project beyond surrounding plastics frame to form cooling ribs. Cells are held together with 2 end plates by pull rods. USE/ADVANTAGE - Starter and traction batteries with specific battery output 75 Wh/kg can be prepd.
