At the 2026 Mondial de l’Auto in Paris, Taiwanese battery innovator ProLogium introduced a novel electrolyte architecture that it calls the Dynamic Coordination Network (DCN). Unlike the traditional binary classification of liquid versus solid electrolytes, DCN creates a third transport regime for lithium ions, blending the fluidity of liquid systems with the safety of solid ceramics. The company presented the technology from its Taipei headquarters and highlighted collaborations with European partners such as Mercedes, FEV and OPmobility.
How the DCN and SFIE work together
The heart of the system is the Superfluidized Inorganic Electrolyte (SFIE), an inorganic medium that can shift between a solid-like lattice and a flow-like state when mechanical stress is applied. In practical terms, the electrolyte behaves like a non-Newtonian fluid: it deforms under the expansion of electrodes during charge, then re-solidifies when the stress eases, preserving intimate contact and lowering interfacial resistance. This unique behavior is achieved through a network of specially engineered ligands that form a dynamic coordination network constantly re-arranging the local environment around lithium ions and allowing rapid short-range hopping.
Performance claims backed by independent testing
Independent measurements witnessed by SGS reported an ionic conductivity of up to 57 mS/cm at ambient temperature, a figure that rivals the best liquid electrolytes while retaining the safety profile of ceramics. ProLogium’s internal data show that cells built with the DCN can charge from 5 % to 80 % state-of-charge in just 6.4 minutes survive more than 1,000 fast-charge cycles and retain over 90 % capacity at a chilling -20 °C. The electrolyte also supports discharge rates of up to 15C underscoring its suitability for high-performance electric-vehicle applications.
Production scale-up and recycling strategy
Beyond the laboratory, ProLogium is expanding its manufacturing footprint. The existing Taoke gigafactory in Taiwan already produces at GWh scale, while construction of a new plant in Dunkerque, France is underway. The first phase aims for an annual output of 4 GWh by 2030, with the infrastructure designed to scale up to 44 GWh if market demand permits. Parallel to capacity growth, the firm announced a recycling loop that can recover the ceramic separator and the SFIE electrolyte with a claimed efficiency of 90 % feeding reclaimed material directly back into production.
Automotive collaborations and road-map
ProLogium’s partnership with Mercedes-Benz has entered a joint testing phase, granting the German automaker priority access to the new Gen4 cells for validation in the upcoming EQS platform. Complementary projects with FEV and OPmobility were demonstrated at the Paris show, showcasing a full battery module and a prototype pack adapted for multiple vehicle segments, from compact city cars to luxury sedans. These collaborations illustrate how the DCN technology can be integrated from cell level up to complete vehicle systems, addressing the diverse performance, cost and safety expectations of the evolving EV market.
With rapid-charging metrics, low-temperature resilience, and a clear pathway toward GWh-scale production and circular recycling, the technology positions itself as a strong contender for next-generation electric-vehicle batteries.
