F the electrolyte plus the resistance in the interface in between the electrode plus the solid electrolyte. In accordance with the information obtained, the additive content at the same time because the heat therapy temperature of the halfcells influence the interface resistance involving the strong electrolyte based on the Li7 La3 Zr2 O12 and LCO/LBO composite cathode. The optimal situations for interface resistance reduce have been reached utilizing composite cathode with 5 wt Li3 BO3 addition annealed at 720 C, Figure 5a. Apparently, the reduce within the sintering temperature for this composite cathode results in a smaller sized get in touch with region among cathode particles and ceramic electrolyte. To make sure a tight make contact with, either a larger glass addition is necessary (ten wt LBO, Figure 5a,b) or perhaps a longer exposure time of sintering must be applied. Hence, a decrease inside the interface resistance from 260 to 40 cm2 at 300 C is observed when a composite cathode with 5 wt Li3 BO3 is applied, in comparison with pure lithium cobaltite.Materials 2021, 14, 7099 Materials 2021, 14, x FOR PEER REVIEW7 of 15 8 ofCa)-Z”, k cm50 Co6 four 2b)300 CRelLCO LCO/LBO fitting resultoWR- Z”, k cmZ ‘, k c mLCO L C O /L B O fittin g re s u lt- Z”, k cm-Z”, cmR el1 MHz15 kHzZ ‘, k c mZ’, cm c m Z ‘, kC (b).

Li4 Ti5 O12 /Li3 BO3 Composite AnodeDSC curves of LTO and c-LLZ mixture with all the very same weight ratio have been investigated to determine the feasible items of their interaction, Figure 1. The endothermic peaks at 250 and 430 C could be referred to as the removal of adsorbed water and CO2 from the c-LLZ sample, respectively [45,46]. The endothermic peak at 588 C is usually referred to the removal of lithium oxide leading to La2 Zr2 O7 formation around the solid electrolyte powder surface, the reflections of which can be detected in the XRD patterns in the LTO and c-LLZ mixture annealed at temperatures above 600 C, Figure 7a. The endothermic peak at 760 C is almost certainly related to chemical interactions amongst the components. Hence, the XRD an.
