Plating method of electrode can of flat alkaline cell and plating apparatus thereof

摘要

A plating method of a negative electrode can of a flat alkaline cell and a plating apparatus thereof are provided, by which a plated-coating layer can be formed only in a concave of the negative electrode can, a plating liquid is not uselessly consumed, and an inner face of the negative-electrode-can can be washed with a small amount of washing liquid. An electroless plating liquid is filled into the concave of the negative electrode can so as to form a plated-coating layer on an inner face of the concave. The electroless plating liquid is recovered from the concave of the negative electrode can, then a washing liquid is filled into the concave to wash the inner face of the concave. Then, the washing liquid is recovered from the concave of the negative electrode can, and then air is filled into the concave to dry the inner face of the concave.
