In this report, using atomic layer deposition (ALD) technique, TiO2 layer with different thickness is conformally deposited on the surface of MoO3 nanobelts for enhanced-performance anode. Impressively, the MoO3@85-TiO2 (85 cycles coating) nanobelts anode shows its best comprehensive value: The initial Coulombic efficiency (CE) dramatically increases from 44% to 73% compared to bare MoO3 electrode; It also delivers highest initial specific capacity of 1153.7 mAh g(-1) at 100 mA (-1), which is superior to the uncoated MoO3 (427.3 mAh g(-1)). Additionally, MoO3@85-TiO2 nanobelts show a remarkable long-life stability from initial 913.6 to 935.8 mAh g(-1) after 400 charge-discharge cycles at 400 mA g(-1). The advanced TEM characterizations reveal that the TiO2 layer can experience a transition from amorphous into crystalline Li2Ti2O4 with cubic structure (a = 8.375 angstrom) during cycling, which are acted as an efficient lithium ion conductor. Furthermore, the quantified mechanical properties demonstrate a remarkable decrease in the bending elastic modulus of MoO3@85-TiO2 nanobelts compared to that of pristine MoO3. Therefore, the boosted electrochemical performance can be attributed to efficient lithium ions transportation across the moderate conductor layer and robust mechanical integrity that the large volume variation. These results advance the understanding in the coating regulated materials for enhancedperformance LIBs. (C) 2018 Elsevier Ltd. All rights reserved.
