ABSTRACT:
A small to miniature pressurized secondary cell of planar configuration has a case comprising a generally cylindrical sidewall open at one end and closed at the other end by a circular end wall. The open end of the case is closed by a cover which includes a positive terminal electrically isolated from the case. A plurality of substantially rectangular positive and negative stacked electrode plates with interleaved separator components are supported within the cell to define chordal volumes between the stacked electrode plates and the cylindrical sidewall of the cell sufficient to establish equilibrium gas pressures within the cell. The positive electrode plates are connected to the positive terminal and the negative electrode plates are electrically grounded to the case. Compressible electrolyte reservoir plates can also be provided at one or both ends of the stacked electrode plates to provide additional electrolyte during the service life of the cell and to absorb expansion of the electrode stack.
