METHOD OF FABRICATION OF POSITIVE ELECTRODES FOR VOLTAIC CELLS, PARTICULARLY FOR LITHIUM-MANGANESEDIOXIDECELLS

摘要

1. A process for the production of positive electrodes for electro-chemical elements with nonaqueous electrolytes, especially Li/MnO2 - cells, in which manganese dioxide is used as the active material, which in admixture with a conducting medium and a matrix is formed into the electrode and is subjected to a final heat treatment, characterized in that, a synthetic manganese dioxide with a delta - crystal structure is used, which after production of the moulded article is subjected to the final heat treatment betwen 180 degrees C and < 200 degrees C.
