(JP2001110381-A)   NOVELTY - Electrode plates (5) having laminated anode and cathode plates with intermediate separator, are arranged within prismatic cell case (3) which has longer and shorter lateral walls (3a). Positive and negative polarity collector plates (6) are fixed to respective anode and cathode plates. The plates (6) are fixed to shorter walls at preset position, by fitting protrusions (26) on plates to holes (8) in walls.    USE - E.g. nickel metal hydride battery module used as drive source in electric vehicle.    ADVANTAGE - Since the electrode plate group is fixed to the case through the collector plates, the electrode plate can be properly fixed in position inside the case, regardless of the positional displacement between the lid and case during welding. Hence sufficient gap between electrode plate group and inner faces of the case can be maintained to allow expansion and compression of electrode plates during charging and discharging cycles, thus preventing deterioration of battery performance due to deformation of the electrode plates.
