Abstract

The rate of lithium ion insertion in different types of manganese dioxide, depending on their pretreatment temperature, was investigated. To obtain maximum utilization at heavy discharge drains, the optimum thermal pretreatment temperature for different chemical and electrochemical manganese dioxides (CMD and EMD) was determined. For most types of MnO<sub>2</sub> samples this temperature is 300 °C. The manganese dioxides studied display a correlation between their specific surface area and specific capacity by weight. The specific capacity by volume of different CMD and EMD samples was compared in lithium button cells. Their specific electrochemical characteristics were studied at high discharge rates in a wide temperature range. Owing to its high utilization CMD Faradiser M appears to be an excellent cathode material, especially at heavy discharge drains and low temperatures.
