Fig. 1.1 XRD diffractogram of a Li3ClO – crystalline sample and of a Li3-0.005Ba0.005ClO – glassy sample at room temperature after EIS measurements (after six cycles of heating/ cooling). Compton's scatter, which is inelastic scattering and amorphous scatter related to the glass is observed. There is evidence of the presence of a hydroxide phase, possibly Li5Cl3(OH)2 , that due to sample's air exposed manipulation is inevitable and starts to form at the surface.

Fig. 1.2 EIS experimental and fitted data using the equivalent circuit previously described. Nyquist impedance and corresponding fitting curve for the 2nd cycle of a sample containing Li3-0.005Ba0.005ClO, at 25 C. A is the surface area, A = 1.76 cm2 and d the thickness, d = 0.2 cm.

Fig. 2.1 Shows the results of chronopotentiometry on a symmetric Li-metal/Li-glass/Li-metal cell with calcium-doped Li-glass, Li2.99Ca0.005OCl. The cell voltage was reversed every 20 min. at a current of 0.10 mA cm-2 during 19 days in an argon-filled glove box.
