Effect of Synthesis Temperature on Structure and Electrochemical Performance of Spinel-Layered Li<sub>1.33</sub>MnTiO<sub>4+z</sub> in Li-Ion Batteries

Effect of Synthesis Temperature on Structure and Electrochemical Performance of Spinel-Layered Li<sub>1.33</sub>MnTiO<sub>4+z</sub> in Li-Ion Batteries

Herein, the spinel-layered cathode material Li<sub>1.33</sub>MnTiO<sub>4+z</sub> (0.8LiMnTiO<sub>4</sub>•0.2Li<sub>2</sub>Mn<sub>0.5</sub>Ti<sub>0.5</sub>O<sub>3</sub>) is investigated for the purpose of developing a...
