Abstract

The authors regret that the Experimental section was missed. The correct one should be as follows. This correction have no impact on the remainder of the manuscript, the interpretation of the data, or the conclusions reached. The authors would like to apologize for any inconvenience caused. Experimental Materials The solvents of ethylene carbonate (EC) and ethyl methyl carbonate (EMC) were purchased from the Beijing Institute of Chemical Reagents. Lithium Hexafluorophosphate (LiPF6) were purchased from Alfa Aesar. All of the lithium salts and solvents were analytically pure. LiNi0.5Co0.2Mn0.3O2 cathode materials (NCM523 coated on Al foil) and graphite anode were purchased from Shenzhen Kejing Star Technology Co., Ltd., containing 80 wt% active materials, 10 wt% super P, and 10 wt% polyvinylidene fluoride (PVDF) binder. The areal loadings of NCM523 cathodes were about 12.6 mg cm−2 with a capacity of 2.3 mA h cm−2, and the areal loadings of graphite anode was about 6.7 mg cm−2 with a capacity of 2.5 mA h cm−2. The diameter of the graphite anode and NCM523 cathodes were both 13 mm. Li metal foil (500 μm) with a diameter of 16 mm was commercially available from China Energy Lithium Co., Ltd. All the electrodes were dried under vacuum for 6 h before use, the size of all the cells tested in the work is CR2032. Electrochemical characterizations LiPF6 was dissolved in EC/EMC (3:7) to prepare the 1.0 M LiPF6-EC/EMC electrolyte, both the Li|Graphite half battery and the Graphite | NCM full battery are matched with the 1.0 M LiPF6-EC/EMC electrolyte. The electrochemical measurements of CR2032 coin cells under different temperatures were conducted in CT4005 high-low temperature chamber (Chongqing SD Experiment Instrument Co., Ltd), and the frequency ranges from 105 to 10−1 Hz under voltage amplitude of 10 mV. All the electrochemical measurements were conducted on Solartron 1470E electrochemical workstation (Solartron Analytical, UK). The Li|Graphite CR2032 coin cells with a capacity of 2.5 mA h cm−2 were cycled at 0.1 C (≈372 mA g−1 based on graphite anode materials) within a voltage range of 1.5–0.001 V. The NCM | Graphite CR2032 coin cells with a capacity of 2.3 mA h cm−2 were cycled at 0.1 C (≈182 mA g−1 based on NCM523 cathode materials) within a voltage range of 3.0–4.3 V. These battery cycling tests were all conducted using LAND multichannel battery cycler (Wuhan LAND Electronics Co., Ltd.). All the cells were assembled in an Ar-filled glove box with O2 and H2O content below 0.1 ppm.
