Abstract
An electrochemical cell that has a compact block formed by an assembly of first and second electrodes of opposite polarity separated by separator means. The block is housed in a container having a base and a cover. The rim of the container is turned down over the periphery of the cover to seal off the container contents. The borders of the first electrode project from opposite ends of the block and bear against the base and the cover. The invention is particularly applicable to a cylindrical cell having a spirally wound electrode block.
