The structural change of Li[NixCoyMnz]O2 cathode materials (x+y+z=1) during the electrochemical delithiation/lithiation was studied with the in-situ X-ray diffraction. It was found that the cathode having the larger Ni fraction of Ni gave the larger unit cell volume change (ΔV) during the reaction. While the initial capacity increased with an increase in the Ni fraction, the capacity fading became...
High-voltage cathode material, LiMn1.5Ni0.5O4, was successfully prepared by two-step process: LiMn1.6Ni0.4O4 particles were obtained by the solid state reaction of oxalate precursors at high temperature such as 900°C and then the LiMn1.6Ni0.4O4 particles with Li-acetate di-hydrate and Ni-acetate tetra-hydrate were annealed at low temperature. Both spinel phases are ferromagnetic compounds: LiMn1.5...
