Boosting the electrochemical performance of MoO3 anode for long-life lithium ion batteries: Dominated by an ultrathin TiO2 passivation layer

In this work, amorphous TiO2 layer with different thickness (sub 10 nm) is homogenously coated MoO3 nanobelts by atomic layer deposition method. As an anode for LIBs, compared to the bare MoO3 nanobelts, the MoO3@85 cycles TiO2 nanobelts show a remarkable boosted capacitance and long-life stability, which is attributed to the high interfacial Li + transport paths and mechanical integrity regulated by the ultrathin layer.107
