LiMn2O4 is a battery cathode material with desirable properties such as low cost, toxicity, high natural abundance of Mn, and environmental compatibility. By means first-principles calculations, we study the structural, magnetic, electronic under ambient conditions hydrostatic pressures (until 20 GPa). We obtain two oxidation states for even using cubic structure, which differ in all analyzed p...

Real-time monitoring of the mechanical behavior cathode materials during electrochemical cycle can help obtain an in-depth understanding working mechanism lithium-ion batteries. The LiMn2O4 composite electrode is employed as in this artificial cell, which conceived and produced along with a chemo-mechanical coupling measurement system. multi-layer beam made monitored real time using CCD camera ...
