Solid-state electric vehicle battery technology company Natrion announced performance metrics for its patented solid-electrolyte separator in lithium-ion battery cells using graphite anode.
The new material, LISIC278, is a version of New York, US-based Natrion’s patented Lithium Solid Ionic Composite (LISIC) electrolyte. It mimics the exact specifications of a standard polyolefin separator while utilising significantly less liquid electrolyte.
The company said LISIC does this by delivering high ion transport capability at ambient conditions. At the same time, it has a thermal resilience of more than 200°C and is fully dense (zero porosity). The claim is a result of near-zero fire risk for batteries built with LISIC, and a significantly reduced ability for a thermal event to intensify or expand.
“Reducing our reliance on flammable liquids in EV batteries is key to reducing fire risk and ultimately making mass EV adoption more viable. So the fact that this data shows we can produce battery cells that are just as efficient with only a small fraction of that liquid is a huge win,” said Natrion co-founder and CEO Alex Kosyakov.
Natrion tested its new material over multiple controlled lab experiments using pouch cells up to 11 layers in thickness.
Compared with the conventional cell, Natrion’s LISIC278 demonstrated:
- 40% faster charge time
- lower fire risk
- high initial coulombic efficiency.
