Dataset on a primary lithium battery cell with a ferroelectric Li-glass electrolyte and MnO2 cathode

Abstract

Here we show the electrochemical data for a Ferroelectric Electrolyte Battery (FEB) Li/ferroelectric Li-glass electrolyte (Li2·99Ba0·005ClO) in cellulose/γ-MnO2 pouch-cell with (2.5 × 2.5 cm2) discharged with a green LED load. The Li2·99Ba0·005ClO electrolyte was synthesized and ground in ethanol. A cellulose matrix was dipped into the Li-glass/ethanol slurry. The γ-MnO2 based cathode was doctor bladed onto a carbon-coated aluminum foil current collector. The cell was assembled in an Ar-filled glove-box and it was not sealed and, therefore, it remained inside the glove-box while discharging with a green LED at approximately 24 °C for 334 days (>11 months) corresponding to 764 mAhg−1 of the active cathode and to 224 mAhg−1 of the electrolyte. The maximum capacity of γ-MnO2 is 209 mAhg−1 and of the MnO2 in the commercial cell is 308 mAhg−1, corresponding to LiMnO2; therefore, the capacity of the FEB is 370% the capacity of the γ-MnO2 and 250% the capacity of the MnO2 in the commercial cell. Moreover, the experimental capacity of the electrolyte minus the maximum capacity of the γ-MnO2 is 163 mAhg−1 of the electrolyte. The potential difference between anode and cathode in a diode is non-linear and dependent on the input current and, therefore, the plateaus in the potential vs time curves do not correspond to thermodynamic equilibria of the electrochemical cell energy source. Nevertheless, the maximum output current as well as the FEB cell's discharge profile may be determined with an LED and compared with traditional battery cells' profiles. The present data might be used by the electrochemical (in particular, battery), electrostatic and ferroelectric materials researchers and industrials for comparative analysis. Furthermore, it can be reused to calculate the maximum energy stored electrostatically in these devices.
