(a) Representation of the solid-state lithium-ion battery with MoS₂ nanosheets as the positive and a lithium–indium alloy as the negative electrode, and β-Li₃PS₄ as the solid electrolyte. The table shows the specifications of the MoS₂ composite electrode (absolute material amounts for the electrode with a diameter of 10 mm, weight, and volume fractions by assuming bulk densities), areal loading of MoS₂, and theoretical capacity values based on q_th = 670 mAh g⁻¹ (MoS₂). The experimentally determined thickness of the MoS₂ composite electrode is approximately 40 μm. (b) (A, B) Charge–discharge profile and cycling performance of MoS₂ nanosheets at the current rate of 0.1C in the potential window 0.01–3.00 V vs. Li⁺/Li–In, and the corresponding Coulombic efficiency. (C, D) Rate performance charge–discharge profile and cycling performance of MoS₂ nanosheets at different current densities in the potential window 0.01–3.0 V (Li⁺/Li–In).
