Lithium manganese oxide (LiMn2O4) Use and Manufacturing

Methods of Manufacturing

The synthesis method uses manganese dioxide, manganese carbonate, manganese nitrate or manganese acetate and lithium hydroxide, lithium carbonate or lithium nitrate as raw materials, and accurately analyzes the composition and content of various materials, so that the molar ratio of lithium to manganese is in the range of 0.45 to 0.5 After mixing uniformly by ball milling, place it in a mold, press it into a block on a hydraulic press, and place it in a high-temperature sintering furnace at a temperature of 600-800℃. After sintering for a total of 36 hours, take out the crushing ball mill and pass through a 300 mesh sieve , Collect products. Its synthesis 4MnO2+Li2CO3→2LiMn2O4+CO2↑+0.5O24MnCO3+Li2CO3+1.5O2→2LiMn2O4+5CO2↑4MnO2+2LiOH→2LiMn2O4+H2O+0.5O2

Uses

High performance lithium ion battery cathode material.
