ProLogium Technology has introduced its fourth-generation superfluidized inorganic solid-state electrolyte, designed to enable scalable mass production of next-generation solid-state lithium batteries. The new electrolyte combines the high ion concentration of solid materials with the interfacial adaptability of liquids, addressing three key challenges in solid-state battery development: ionic conductivity, interfacial stability and manufacturing efficiency.
Third-party testing by SGS confirms that the electrolyte achieves 57 mS/cm ionic conductivity at 25 °C, roughly five to six times higher than conventional organic liquid and sulfide solid electrolytes. This performance supports ultra-fast charging, allowing cells to charge from 5 percent to 60–80 percent in just four to six minutes. At –20 °C, the electrolyte maintains 12.82 mS/cm conductivity—surpassing the room-temperature levels of typical liquid and solid electrolytes—and sustains 90–95 percent discharge efficiency, compared with a 40–50 percent drop in conventional batteries under similar conditions.
ProLogium’s proprietary fluidization technology gives the solid electrolyte the interface properties of a liquid, accommodating the volume changes of active materials during charge-discharge cycles. This eliminates delamination, reduces internal resistance, removes the need for pressurization modules and boosts overall energy density. The solution is tailored for a wide range of applications, including electric passenger vehicles, commercial trucks, construction machinery, aerospace, marine propulsion and large-scale energy storage.
Founded in 2006, ProLogium holds over 1,000 patents worldwide. To accelerate commercial deployment, the company is launching a collaborative framework of technology licensing, strategic alliances and regional manufacturing. Under this model, ProLogium will license its electrolyte and electrode-modification technologies while producing cell-level inlays for partners using a semiconductor-style vertical specialization approach. Agreements will span material suppliers, equipment manufacturers, module integrators and end users, fostering co-creation across the global solid-state battery ecosystem.
With its first gigafactory in Taiwan operational since 2024 and plans for an overseas facility in France, ProLogium positions this electrolyte innovation as a critical platform for driving the energy transition and supporting net-zero objectives.
