| Summary: | This study has investigated the effect of 2-dimensional (2D) beta borophene as a cathode additive for all-solid-state lithium-sulfur batteries. The comparisons have been carried out regarding the impact on ionic conductivity based on borophene content. Although the studies of borophene's contributions in the literature on the anode component, this study focuses on the cathode contribution for the first time. While MoS2 has been selected as the cathode active material, carbon black has been selected as the electrical conductor, and Li7P3S11 solid electrolyte has been synthesized as an ionic conductor in all-solid-state lithium-sulfur cells. Borophene has been synthesized from boron powder by the exfoliation method. As a cathodeactive material, MoS2, containing sulfur, and its 2D material nature, eliminates many of the disadvantages that sulfur exhibits when used alone. To investigate the effect of borophene on ionic conductivity in all-solid-state lithium-sulfur cells, multicomponent composite cathodes were prepared in (MoS2 / Conductive Carbon / Li7P3S11 + Borophene) overall compositions. According to the results, the specific capacity of the cells is affected negatively, while the stability of the cell is affected positively when increased the borophene amount. |
