摘要

This patent pertains to a process for preparing nickel coatings in conducting, porous bodies, especially for battery electrodes. In the process, a nickel layer is first galvanically applied on the body, characterized in that the body with its galvanic nickel layer is heated to a temperature above 200 deg C on the inside and a temperature below 200 deg C in peripheral zones by ohmic heat in a carbon monoxide atmosphere, whereby nickel is introduced as a coating from the nickel layer into the body. An electrical current is sent through the body for the ohmic heating in the direction of a longitudinal axis or a thickness axis. The body is heated under pressure. The carbon monoxide atmosphere is pressed through the body. Up to 50% hydrogen is mixed to the carbon monoxide atmosphere. Up to 10% nickel tetracarbonyl is mixed to the carbon monoxide atmosphere.
