Özet
Abstract: All-solid-state batteries (ASSBs) have come into focus in recent years as energy storage devices with energy densities potentially exceeding those of conventional lithium-ion batteries (LIBs). However, in practice, severe problems still must be solved. To reach high energy densities, it is indispensable to use lithium as anode and to build composite cathodes with high active material loading in the range of 85 wt %. In order to achieve fast ion transport inside the cathode despite the high active material loading, the solid electrolyte should have a high ionic conductivity and should form a continuous phase with low tortuosity ion transport pathways. By this research, we tested the conductivity amounts from various substrates containing amorphous glass, SSBM, and with glass-ceramic samples. Via SSBM technique, silicon nanoparticles were used as anode material, and it was exhibited the charge and discharge curves in the battery cell was cycled between 0.01 and 1.5 V versus Li+/Li at a current density of 220 mA g–1 at room temperature. Since the high resistance, causes degradation of the interface between the cathode material (LiCoO2) and the solid electrolyte, we added GeS2 and SiS2 to the Li2S–P2S5 system for obtaining higher conductivities and better stability of the electrode/electrolyte interface.
