| description | The present work addresses the issues related to the capacity fading of spinel LiMn<sub>2</sub>O<sub>4</sub>, such as Mn leaching and Jahn–Teller distortion and suggests an advanced TiN-coated LiAl<sub>0.1</sub>Mn<sub>1.9</sub>O<sub>4</sub> (LAMO) cathode material as an electrode for lithium-ion batteries. TiN coating layers with the same thickness but a different porosity cover the LiAl<sub>0.1</sub>Mn<sub>1.9</sub>O<sub>4</sub> electrode via reactive magnetron sputtering, and present promising electrochemical behavior. In contrast with the pristine LiAl<sub>0.1</sub>Mn<sub>1.9</sub>O<sub>4</sub>, the dense TiN-coated LiAl<sub>0.1</sub>Mn<sub>1.9</sub>O<sub>4</sub> electrode demonstrates a remarkable long-term cycling by reducing the contact area of the electrode/electrolyte interface, resulting in structure stabilization. |
