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.

本数据集展示了锂负极/铁电锂玻璃电解质/增塑剂/富锂氟掺杂LNMO正极扣式电池的电化学原始数据，其中增塑剂为丁二腈（succinonitrile, SN）。活性氧化物基正极颗粒的标称组成为Li₁.₃₆Ni₀.₄₉Mn₁.₁₅O₃.₂₈F₀.₃₆（LNMO），该组分可歧化为78 wt%的尖晶石相LiNi₁/₂Mn₃/₂O₃.₈F₀.₂以及22 wt%的富锂氟掺杂层状相，该层状相包含由Li⁺与Ni²⁺离子分隔的Li₂MnO₃片层。Li₂.₉₉Ba₀.₀₀₅OCl电解质通过乙醇溶剂合成并研磨制备，将纤维素基体浸渍于玻璃/乙醇浆料中。该电池已循环测试两年六个月，其电化学性能曾在循环约一年三个月后以图表形式发表[1]。本Li//LNMO CR2032扣式电池在氩气保护手套箱中组装，并于室温下在LAND电池测试分析仪中进行电化学测试，测试采用恒定比电流密度，电位区间为2.5~4.8 V，循环电流为23 mA·g⁻¹（活性正极）。本数据集可供电化学（尤其是电池领域）、静电学与铁电学领域的研究人员及工业从业者开展对比分析使用，亦可被所有希望计算静电最大储能的固态器件研究者重复使用。
