Process for the production of a porous aluminum matrix for the negative electrode of a galvanic cell, in the charged state, having lithium aluminum and metal sulfide elements (or electrodes). Aluminum powder is thoroughly mixed, e.g., by grinding, with a fine salt, which is soluble in water and which serves as an expanding agent. Coarser particles of the same expanding agent (about 100 to 500 mu m in size) are then added. The matrix is finally completed by hot pressing at a temperature of 150 DEG to 300 DEG C. and a pressure of at least 500 bar and by the expanding agent being subsequently dissolved out of the matrix using water.
