At -20°C, the SF-Ceramion™ electrolyte still achieves an impressive ionic conductivity of 12.82 mS/cm, exceeding the room-temperature conductivity of conventional organic liquid electrolytes and sulfide solid electrolytes. Discharge efficiency remains at 90–95%, significantly outperforming traditional batteries that experience severe performance drops under low-temperatures.

Stable Output in Low-Temperature Environments
Even in environments as cold as -20°C, the system retains more than three times the lithium-ion conductivity of conventional batteries. Combined with its strengths of high migration and concentration, the system delivers 90–95% discharge efficiency for automotive use— a stark contrast with typical 50–60% performance decline of traditional batteries under low temperatures. This breakthrough eliminates range anxiety for EV users in cold climates and offers critical competitiveness for deployment in polar regions, as well as in defense, aerospace, and other demanding domains.

Breakthroughs in Materials and States of Matter  Solve the Key  Interface Challenges
Through its proprietary fluidization technology, ProLogium has successfully endowed solid-state electrolytes with the interface adaptability typically seen in liquid electrolytes. This allows the electrolyte to conform to the surfaces of active materials, which undergo dramatic volume changes during charge and discharge cycles. The result is long-term cycle stability without delamination or increased internal resistance, and save the need for external pressurization modules or structural compensator units such as pressurizers. This reduces system complexity and increases energy density.
