ProLogium wins third Edison Award for Gen 4 superfluidized all‑inorganic solid‑state battery
- Gen 4 electrolyte achieves ~100% ionic transference and 57 mS/cm ionic conductivity — over 5× higher than conventional liquid and sulfide electrolytes.
- Cell volumetric energy density of 860 Wh/L and supports 60–80% charge in 4–6 minutes while keeping 90% performance at −20°C.
- Dual‑function non‑flammable electrolyte can release an Active Safety Mechanism (ASM) in situ to passivate electrodes and prevent thermal runaway.
- Manufacturing claims: no rare materials, BOM comparable to liquid electrolytes, 30–40% fewer process steps and 60–70% reduction in dry‑room requirements.
Award and context
ProLogium received a Gold Edison Award in the Battery Materials & Manufacturing category for its Gen 4 Superfluidized All‑Inorganic Solid‑State Lithium Ceramic Battery at the Edison Awards gala on April 16 in Fort Myers, Florida. This is the company’s third Edison Award, following a 2021 recognition for its Active Safety Mechanism (ASM).
Technology roadmap and breakthroughs
Between 2022 and 2024 ProLogium developed an ASM‑embedded all‑inorganic solid‑state electrolyte; in 2024–2025 it reports a breakthrough in superfluidization enabling strong interfacial contact and pressure‑free operation. The platform integrates a non‑flammable, superfluidized electrolyte, an all‑ceramic separator and a 100% silicon anode.
Verified performance claims
Reported metrics include ~100% ionic transference with 57 mS/cm ionic conductivity (over 5× conventional values), 860 Wh/L cell energy density, 60–80% charge in 4–6 minutes, and 90% performance at −20°C. The electrolyte is described as dual‑function: non‑flammable and able to release ASM in situ to passivate electrodes and prevent thermal runaway.
Commercialization and applications
ProLogium states the electrolyte uses no rare materials, is recyclable, and can be produced from industrial‑grade feedstock to battery‑grade purity; BOM costs are said to approach those of liquid electrolytes while reducing process steps and dry‑room needs, targeting EVs, aerospace, energy storage and other mobility applications.
