MnO@MnTiO3/TLG anode material with excellent performance for lithium-ion batteries/capacitors

MnO has many advantages as an anode material for lithium-ion electrochemical energy storage system, but the poor cycle performance of MnO anode material is always a pain point. In this work, MnTiO3 is used as a coating layer and thin-layer graphite (TLG) is introduced as a skeleton to achieve a significant improvement in the cycle performance of MnO anode materials. MnO@MnTiO3/TLG materials have been systematically characterized, which fully illustrates the existence of the coating layer and framework structure and also clarifies the positive influence of this special structure on the material properties. At the current density of 100 mA g−1, the initial discharge capacity of the material is about 600 mAh g−1, the initial coulombic efficiency is about 71
