Abstract
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.degree. to 300.degree. C. and a pressure of at least 500 bar and by the expanding agent being subsequently dissolved out of the matrix using water.
