Abstract
An electrical-storage battery includes a cell defined by two spaced-apart graphite electrode-plates one of which forms a cathode and the other an anode. The cell contains an electrolyte which is an aqueous solution including sulfuric acid. In a charged condition, the electrode-plate which forms a cathode has a surface layer of lead in contact with the electrolyte, and the electrode-plate which forms the anode has a surface layer of manganese dioxide in contact with the electrolyte. In a battery having multiple cells arranged in electrical series, a single graphite electrode-plate physically separates adjacent cells, but electrically connects the cells. This electrode-plate serves as a cathode for one of the adjacent cells, and as an anode for the other.
