Accumulator cell
A storage battery comprising a plurality of cells supported one upon another is described. Each cell includes a cuboid housing of nonconducting material with a liquid electrolyte and positive and negative plate elements therein. The top and bottom sides of the housings have shapes that are complementary to each other in such a way that the cells stack compactly one upon another. An open communication path exists between the liquid electrolyte in the housings of adjoining cells. Electrically conducting means including positive and negative terminal conductors extend through the housings and are liquid tight. Electrical conductors outside the housings of the cells interconnect plate elements of like polarity of adjoining cells. Terminal connecting means interconnecting plates of the same polarity in each cell may include cylindrical lead members extending through the top sides of the housings and sealed fluid tight by injected lead bushings and means including electrical conductors outside the housings of said cells interconnecting plates of like polarity of adjoining cells. A member on the top of the housing, outside the dividing line between the material of the top side of the housing and the lead bushings, may be provided with internally threaded portions concentric with and radially spaced from the cylindrical lead members and annular means threaded into the internally threaded portions for exerting sealing pressure at dividing line.
