Claims31
A rechargeable electrochemical cell, comprising:
- interleafed first and second plates of opposite polarity, the first plate including a film made primarily from lead and a porous electrochemically active paste coated onto both sides of the film, the first plate being less than about 0.01 inches thick and the first plate film being substantially non-perforated and less than about 0.005 inches thick;
- a polous separator interposed between the first and second plates, the separator having electrolyte in the pores;
- and a container to contain the plates and separator.
A method for manufacturing an electrochemical cell, comprising interleafing first and second plates of opposite polarity separated by a separator, the first plate including a film made primarily from lead and a porous electrochemically active paste coated onto both sides of the film, the first plate being less than about 0.01 inches thick and the first plate film being less than about 0.005 inches thick.
