An electrochemical cell with a specifically designed X-ray window was fabricated in order to evaluate the structural evolution of the cathode material under the operating condition. It enabled us to obtain strong signals from a positive electrode ...
Li-Mn spinel oxide cathode materials were prepared using Mn2O3 particles, which were derived from the thermal decomposition of Mn-acetate or Mn-oxalate particles. The effects of the molar ratio of Li/Mn and the reaction temperature on the produced...
