چکیده انگلیسی
Li4-xMgxTi5O12 (0 â¦Â X â¦Â 0.2) anode material was synthesized by a solid-state method using Li2CO3, MgO and anatase TiO2. The effects of Mg element doping on the crystal structure, phase composition, morphology and electrochemical properties of Li4-xMgxTi5O12 were investigated by XRD, SEM and EDX. The electrochemical properties of Li4-xMgxTi5O12 were characterized through Cyclic voltammetry and AC impedance experiments. The results indicated that when x = 0.10, the resultants show better electrochemical performance in higher rates cycle stability and the polarization degree. The initial discharge capacity reaches 122.5 mAh/g at 2 C, and the discharge capacity still remains 119.3 mAh/g after 100 cycles.
