Ni-rich layered oxides (NLOs) are widely considered as one class of commercially available cathodes for lithium-ion batteries (LIBs), mainly ascribed to their high specific capacities and working voltages. However, two major hurdles of NLOs for practical utilization are their inferior cycling stability and storage property, strongly deriving from the irreversible bulk phase transformations and detrimental surface degradation. Herein, we demonstrate a combination of TiO2 surface coating and Ti4+ bulk doping modification to improve the cyclability and storage property of LiNi0.8Co0.1Mn0.1O2 synchronously. The TiO2 coating layer is established by a simple hydrolytic process followed by a posttreatment at 800 ℃ that leads to Ti4+ doping. Benefiting from the synergetic effects of chemical doping and surface coating, the TiO2coated LiNi0.8Co0.1Mn0.1O2 (811@TiO2) material exhibits superior cycling stability with 9077% capacity retention after 100 cycles at 2C(1C=200 mA·g-1) between 2.8-4.3 V, while that of pristine (811-bare) is just 80.38%. Moreover, after 30 days of air exposure, the 811@TiO2 electrode still retains 86.12% of the initial reversible capacity delivered by the fresh one with 85.31% cycling capacity retention after 100 cycles at 2C, which are greater than the corresponding values of 67.40% and 68.02% for the 811-bare electrode respectively. Served with the analysis of CV,EIS,XPS,XRD,TEM, etc, the improved performances are exhibited and discussed in detail.
