In an alkaline battery, the negative electrode is zinc (anode) and the positive electrode manganese dioxide (cathode). read more
The alkaline-manganese dioxide battery was introduced in the early 1960’s and remains in a strong position in today’s battery market. Theoretically, alkaline-manganese dioxide cells have a higher capacity than Leclanche, or zinc-carbon cells, of similar sizes. read more
Electrolytic manganese dioxide. Electrolytic manganese dioxide (EMD) is used in zinc–carbon batteries together with zinc chloride and ammonium chloride. EMD is commonly used in zinc manganese dioxide rechargeable alkaline (Zn RAM) cells also. For these applications, purity is extremely important. read more
