Structural and electrochemical evaluation of bismuth doped lithium titanium oxides for lithium ion batteries

Micro-sized Li4Ti5−xBixO12 (0 ≤ x ≤ 0.15) materials are synthesized using a simple solid state method in air. The structural, morphological, and electrochemical characteristics of Bi-doped lithium titanates and pristine samples are methodically analyzed by X-ray diffraction (XRD), Raman spectroscopy...
