Electrode for electrochemical cells.

Abstract

A negative electrode for lead-acid batteries consists of a grid plate (11), which serves as a carrier for the active material and the current supply and discharge. The grid plate (11) is composed of plastic fibers and made by a weaving operation network which is made electrically conductive by coating with a highly conductive thin metal layer and is additionally coated with at least one coating of a lead-tin alloy or lead. The grid plate (11) is divided into produced by thermoforming storage areas (12) for receiving the active material and current conducting (14) for the power-supply and accounted.
