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.
Claims22
An electrochemical cell comprising a metal container having a closed base, an open upper end having a rim, a cover, means for effecting a seal between the container and cover, and a compact block positioned within said container comprising an assembly of electrodes of opposite polarity and separator means between such electrodes, one of said electrodes having conductive borders respectively projecting outwardly from opposite ends of said block, said borders resepctively bearing against the cover and base of said container, said borders providing supports for said block between the cover and base of said container.
