In the description, a hydrogen storage alloy electrode comprising a hydrogen storage alloy and a conductive metal and completely free of organic binder is disclosed, wherein at least two layers of an active material holding layer and a conductive metal layer essentially are integrated into an electrode sheet having a conductive network communicating throughout the electrode. The electrode can be used in a nickel-metal hydride storage battery, for example, particularly exhibits high efficiency charge/discharge characteristics while satisfying general characteristics as a battery, and has a relatively low cost and facilitates recycling.

The apparatus for drying an electrode plate for a battery has: a support drum of a cylindrical shape having a peripheral face on which a long sheet-like electrode plate for a battery is to be wound, and in which a large number of blow holes for allowing the electrode plate for a battery to run in a levitated manner are formed; external air blowing means which is adjacent to the support drum and which has a blowing port through which air is blown to a surface of the electrode plate for a battery wound on the support drum; and moving means for causing the electrode plate for a battery to run in a longitudinal direction of the electrode plate for a battery. The heat loss is small and the productivity is excellent, and a high-performance battery electrode plate which is free from a crack and a scratch and which has a stable quality can be produced.
