Sulfide solid electrolytes (SSEs) have some huge advantages in high room-temperature conductivity, good thermal stability, low interfacial resistance, etc. They are one of the ideal for developing energy density and safety all-solid-state lithium batteries (ASSLBs). However, preparation SSEs requires expensive Li2S as raw material, whose cost limits its practical application. Herein, a cost-effective SSE Li7.3P2.9S10.75X0.3 (X = F, Cl, Br, I) was designed prepared by using low-cost sulfur instead Li2S. Significantly, reduced from $169.72 to $28.13 kg–1 based on replacing strategy. Moreover, ionic conductivity 1.86–2.73 mS cm–1 at room temperature voltage window 5 V. On this basis, we assembled battery TiS2/Li7.3P2.9S10.75I0.3/Li–In, which presented initial discharge capacity 219 mA h g–1 satisfactory cycle stability with retention 86.7% after 100 cycles 0.50 cm–2. This work provides an effective strategy reducing SSEs, advancing process ASSLBs.
