June 24, 2025 | Ganzhou, China — Farasis Energy has confirmed that its 60 Ah sulfide all‑solid‑state battery — rated at up to 500 Wh/kg gravimetric energy density — has cleared pilot qualification and will be shipped to strategic customers in small batches before the end of 2025. The announcement, made during a recent investor Q&A, positions the Jiangxi‑based pouch‑cell specialist to become the first Chinese manufacturer to commercialise large‑format sulfide ASSBs.
At 60 Ah, Farasis’ prototype more than doubles the capacity of the 20 Ah laboratory cells that still dominate most peer road‑maps. Company engineers say the milestone was achieved through a stacked soft‑pack architecture that minimises inactive material and mitigates interfacial stress, allowing consistent pack‑level densities exceeding 400 Wh/kg and peak results touching 500 Wh kg⁻¹ during certification tests.
Commercialisation will leverage the firm’s Smart Pouch Solution (SPS) lines, which are designed for “full‑flex” switching between liquid, semi‑solid and solid chemistries. An initial 6 GWh slice of existing capacity in Ganzhou is already being retro‑fitted, while an additional 4 GWh extension is under construction; management says this approach cuts lead‑time and capital cost versus green‑field solid‑state factories.
Farasis continues to pursue parallel oxide/polymer and sulfide routes, but notes that sulfide electrolytes — with ≥10 mS/cm ionic conductivity — “offer the fastest lane to 500 Wh/kg”. Interface engineering, coupled with cold‑isostatic pressing, has pushed interfacial resistance below 15 Ω cm², and 60 Ah cells retain 80 % capacity after 800 cycles at 25 °C.
Analysts say Farasis’ timetable outpaces global rivals such as Toyota, Solid Power and Samsung SDI, which do not expect 40–60 Ah sulfide cells until 2027–30. Early volumes will target eVTOL, humanoid‑robot and premium range‑extender applications, but the company’s soft‑pack pedigree could ease the transition into passenger‑EV packs once cost curves permit. If scale‑up proceeds as planned, Farasis will catalyse a broader industry shift from semi‑solid to true solid‑state architectures, underscoring China’s accelerating leadership in next‑generation battery technology.
