Modification of lithium titanate spinel by d-electron metals
A simply and cheap solid state synthesis was used to produce powders of spinel phase Li4-xCuxTi5O12, where 0≤x≤0.2, with crystallite size in ~890 nanometers range. The as-prepared samples were verified by scanning electron microscopy and X-ray diffraction. The electrochemical performance of these sa...
