METHODS OF AND APPARATUS FOR MAKING CATHODE ELECTRODES FOR SODIUM SULPHUR CELLS

摘要

A cathode structure for a sodium sulphur cell is formed by putting a fibre matrix into a mould which is closed to shape the matrix to the required form with compression of the fibrous material, the mould being kept at a temperature below 12 DEG C. and preferably between 8 DEG and 10 DEG C. while liquid sulphur is injected into the compressed fibre material.
