Dataset on a ferroelectric based electrostatic and electrochemical Li-cell with a traditional cathode

Here we show the electrochemical raw data for a Li/ferroelectric Li-glass electrolyte/plasticizer/Li rich, F doped LNMO coin cell where the plasticizer is succinonitrile-SN. The nominal composition of the active oxide-host cathode particles is Li1.36Ni0.49Mn1.15O3.28F0.36 (LNMO) that disproportionated into 78 wt% spinel phase LiNi1/2Mn3/2O3.8F0.2 and 22 wt.% Li-rich, F-doped layered phase containing Li2MnO3 planes separated by Li+ and Ni2+ ions. The Li2.99Ba0.005OCl electrolyte was synthesized and grinded in ethanol. A cellulose matrix was dipped into the glass/ethanol slurry. This cell has been cycling for two years and six months. The electrochemical performance was firstly published in graphs after cycling the cell for about one year and three months [1]. The electrochemical performances of the Li//LNMO CR2032 coin cell was assembled in an argon-filled glove box and electrochemically tested in a battery testing analyser (LAND) at room temperature and at constant specific current densities and potentials between 2.5 and 4.8 V. Moreover, the cell cycling current was 23 mA.g-1(active cathode). The data might be used by the electrochemical (in particular, battery), electrostatic and ferroelectric researchers and industrials for comparative analysis. Furthermore, it can be reused by anyone interested in solid-state devices that want to calculate the maximum energy stored electrostatically.
