ProLogium unveils DCN third lithium‑ion transport mechanism (SFIE)

Key highlights
  • ProLogium introduces a Dynamic Coordination Network (DCN) based on a Superfluidized Inorganic Electrolyte (SFIE) that establishes dynamic, short‑range lithium‑ion transport pathways.
  • SGS‑witnessed results report SFIE ionic conductivity up to 57 mS/cm at room temperature with a high lithium‑ion transference number.
  • Internal tests show 5%→80% charging in 6.4 minutes, over 1,000 fast‑charge cycles, >90% capacity retention at −20°C and discharge capability up to 15C; ASM passivates at ~125°C.
  • ProLogium names Mercedes‑Benz for joint testing and demonstrates modules/prototypes with FEV and OPmobility; GWh Taoke lines operate in Taiwan and a Dunkirk gigafactory is under construction in France, with SFIE recovery targeted at 90%.

Announcement

ProLogium unveiled its Dynamic Coordination Network (DCN) electrolyte architecture and Superfluidized Inorganic Electrolyte (SFIE) at the 2026 Paris Motor Show, positioning DCN as a third lithium‑ion transport mechanism beyond conventional liquid and solid electrolytes.

How DCN and SFIE work

DCN uses engineered ligands to create continuously changing local coordination structures that constrain anions and increase lithium‑ion transference, enabling rapid ion transfer via dynamic, short‑range pathways. SFIE exhibits non‑Newtonian, adaptive interfacial behaviour that flows under stress and solidifies when stress is released, improving electrode contact and reducing reliance on high stack pressure.

Performance and safety

SGS‑witnessed testing shows SFIE ionic conductivity up to 57 mS/cm at room temperature with a high lithium‑ion transference number. ProLogium’s internal data report charging from 5% to 80% in 6.4 minutes, over 1,000 fast‑charge cycles, >90% capacity retention at −20°C and discharge rates up to 15C. SFIE is paired with an Active Safety Mechanism (ASM) that induces passivation at roughly 125°C to interrupt thermal runaway.

Automotive integration, manufacturing and circularity

ProLogium is working with Mercedes‑Benz on priority testing of Gen4 cells and is showing modules/prototypes with FEV and OPmobility. Manufacturing includes GWh Taoke lines in Taiwan and ongoing construction of a Dunkirk gigafactory in France. The modular battery design aims for closed‑loop recycling: cathode/anode materials routed to third‑party recyclers and ceramic separator plus SFIE recovery targeted at about 90%.
