    • A battery module of the present invention comprises an annular connecting member 10 having an aperture 14 at a position corresponding to a cap 8 provided on a sealing plate 7 and between the sealing member 7 of one cell B and a bottom of a can 6 of the other cell A. The annular connecting member 10 comprises an annular base portion 11 having its outer diameter smaller than an inner diameter of the opening portion of the can 6, a convex portion 12 with bottom protruding upward or downward alternately from the annular base portion 11, and a projection 13 projecting from the bottom of the convex portion 12. Thereby, the connecting portion between the cell A and the cell B has a collecting path of a length between both projections 13, namely, a length between the sealing plate 7 of the cell B and the bottom of the can 6 of the cell A, whereby the voltage drop across the connecting portion decreases, resulting in a battery module having high operation voltage.

    • The present invention aims to provide a method of producing a hydrogen absorbing alloy electrode which is solid and enables a metal hydride storage cell, using the hydrogen absorbing alloy electrode, with high discharge characteristics in high-rate discharge and in low temperature and a long cycle life. To achieve this, the hydrogen absorbing alloy electrode is produced by firstly generating a first powder by giving a surface treatment to a hydrogen absorbing alloy powder in an acid solution, secondly generating a mixed material by mixing the first powder with a second powder which is composed of a metal which does not absorb hydrogen and/or an alloy which does not absorb hydrogen, thirdly attaching the mixed material to a base plate, and fourthly baking the base plate for sintering the mixed material attached to the base plate. The hydrogen absorbing alloy electrode may also be produced by firstly generating a first powder by attaching a nickel-rich metal to the surface of a hydrogen absorbing alloy powder, secondly generating a mixed material by mixing the first powder with a second powder which is composed of a metal which does not absorb hydrogen and/or an alloy which does not absorb hydrogen, thirdly attaching the mixed material to a base plate, and fourthly baking the base plate for sintering the mixed material attached to the base plate.
