NOVELTY - The production of a non-sintered thin electrode for batteries comprises filling into or coating on a conductive electrode substrate in a wide belt-like form with a paste of powders containing active material or pseudo-materials; pressing the coated substrate between a pair of rollers; and cutting into a desirable size. The conductive electrode substrate has innumerable hollow concave and convex parts formed by the unevenness processing.    USE - Used for producing a non-sintered thin electrode for batteries, e.g. secondary batteries (claimed) such as nickel-metal hydride battery used in electric vehicles, hybrid electric vehicles and electric power assisted bicycles.    ADVANTAGE - The electrode has reduced cost, and the high rate discharge characteristics and the cycle life are improved.    DETAILED DESCRIPTION - The production of non-sintered thin electrode for batteries, comprises filling into or coating on conductive electrode substrate (9) in a wide belt-like form with the paste (10) of powders containing active material or pseudo-materials; pressing the filled or coated electrode substrate between a pair of rollers; and cutting into a desirable size. The conductive electrode substrate has unevenness produced on the conductive electrode substrate by unevenness processing except for a part, which remains even with a desirable width at least on both sides along the longitudinal direction. It has innumerable hollow concave (C, C') and convex parts (B, B') formed by the unevenness processing. The thickness of the conductive electrode substrate, which made a thin electrolyte-proof metal plate into a three dimensional form with the concave and convex parts is 0.5-2 times as large as the thickness of the final electrode. The number of concave parts is not less than half the number of concave and convex parts, where the concave parts are adjacent and closest to (groups of) concave parts, or the concave and convex parts are adjacent and closest to (groups of) concave parts.
