Electrochemical data for "Enhancing the Electrochemical Performance of LiNi0.70Co0.15Mn0.15O2 Cathodes Using a Practical Solution-Based Al2O3 Coating"

Abstract

Raw cycling data and electrochemical impedance spectroscopy (EIS) data of the cells investigated in the publication Negi, R.S, Culver, S.P., Mazilkin, A., Brezesinski, T., Elm, M.T. “Enhancing the Electrochemical Performance of LiNi0.70Co0.15Mn0.15O2Cathodes Using a Practical Solution-Based Al2O3Coating” ACS Appl. Mater. Interfaces 2020, 12, 31392-31400; https://doi.org/10.1021/acsami.0c06484. File format is the standard .txt format. Cycling data of the three pristine (uncoated) NCM cathodes (P-NCM) and the three investigated, coated NCM cathodes (C-NCM) are stored in three blocks: 1. Cycle number, 2. Discharge capacity cell1 (mAh g-1), 3. Discharge capacity cell2 (mAh g-1), 4. Discharge capacity cell3 (mAh g-1). Experimental impedance data after the first cycle and the 100th cycle for one pristine (P-NCM) and coated cathode (C-NCM) are stored in 3 blocks: 1. Frequency (Hz), 2. Real part (Ohm), 3. Imaginary Part (Ohm). In each file, blocks 4 and 5 give the results of the fitting according to the equivalent circuit discussed in the publication. Block 4: Fitted real part (Ohm), block 5: Fitted imaginary part (Ohm).
