In order to develop a secondary battery with high energy density, several characteristics of coin-type cells using lithium-containing manganese dioxide as a positive material are investigated. Cells prepared from LiOH and electrolytic manganese dioxide (EMD) display higher energy density (177 Wh l -1 ; 63 Wh kg -1 ) than those prepared from LiOH and chemical manganese dioxide...
The discharge characteristics of lithium nickel oxides have been improved by investigating their synthesizing conditions, such as their raw materials and heat-treating conditions. Lithium hydroxide (LiOH) and nickel hydroxide (Ni(OH) 2 ) were found to be appropriate raw materials, and 750 °C in oxygen atmosphere was the most suitable heat-treating condition. Lithium nickel oxide synthesized...
