Natrion provides an Active Separator that can replace existing lithium‑ion separators in gigafactory lines with a lithium solid ionic composite ceramic‑polymer electrolyte. The drop‑in component boosts specific energy by over 50%, enables 20‑30 minute fast charging, and offers thermal stability from –50 °C to 250 °C, improving safety and supporting both current lithium‑ion and next‑generation lithium‑metal or solid‑state cells without retooling equipment.

Problem
Battery manufacturers face limitations in safety, energy density, charging speed, and operating temperature range with existing lithium‑ion separators, and transitioning to next‑generation lithium‑metal or solid‑state chemistries often requires new production lines and supply chains.
Solution
Natrion’s Active Separator replaces conventional separators on gigafactory lithium‑ion lines with a lithium solid ionic composite (LISIC) ceramic‑polymer electrolyte. The material mitigates degradation mechanisms, enabling up to 50 % higher specific energy and 20‑30 minute fast charging without sacrificing cycle life. Its thermal stability from –50 °C to 250 °C prevents thermal runaway, improving safety for both current and future lithium‑metal or solid‑state cells. Because the separator is a drop‑in, one‑to‑one replacement, manufacturers can adopt the technology without retooling equipment, while also gaining a pathway to higher‑performance chemistries and onshored supply chains.
Target Audience
Primary customers are lithium‑ion battery manufacturers operating at gigafactory scale and developers of next‑generation Li‑metal or solid‑state cells seeking a manufacturable, safety‑enhanced separator solution.
