Introduction Manganese dioxide MnO2 has been successfully used as inexpensive and abundant battery material since its introduction in zinc-carbon batteries with ammonium chloride electrolyte by G. L. Leclanche in 1866. Initially naturally occurring MnO2 was used followed by chemically synthesized manganese dioxide substantially improving the performance of Leclanche batteries. Later the more efficient electrochemically prepared manganese dioxide EMD was applied enhancing cell capacity and rate capability. The pioneering work of Herbert resulted in the first commercialization of the alkaline manganese dioxide-zinc battery in 1952 comprising potassium hydroxide KOH electrolyte. Further improvements . design change powder zinc anodes were achieved by Union Carbide Corp. from 1960 to 1970 leading to a more powerful alkaline cell. The alkaline MnO2-Zn battery has become the predominant primary battery system of today having several advantages over its acidic electrolyte counterpart. Moreover the primary battery was further developed by K. Kordesch to a rechargeable alkaline battery system that is being produced since 1994. The versatile use of electronic consumer products . cellular phones video cameras and laptops and the need for lightweight batteries with high energy and power density have promoted the development of lithium-ion batteries since nearly two decades. Much effort has been focused on manganese-based materials as cathodes in lithium batteries owing to low cost and safety aspects. Lithium-manganese dioxide cells offer a significantly higher voltage than their Zn-MnO2 analogs. In general the voltage depends on the manganese oxidation state and on the MnO2 structure type 1-5 V . The use of host structures such as carbon lithium alloys and metal oxides instead of metallic lithium as negative electrode improved the battery safety .
