Natrion Unveils New Battery Components that Reduce Fire Risks

  • New material LISIC provides high ion transportation capability at ambient conditions while having a thermal strength in excess of 200 ° C and being fully dense.
  • The result is a near-zero fire risk for batteries built with LISIC, and a substantially decreased ability for a thermal event to heighten or broaden.

New York-based solid state electrical vehicle battery modern technology player-- Natrion-- has actually unveiled performance metrics for its trademarked solid-electrolyte separator in Li-ion battery cells utilizing graphite anode. This comes as a growing number of reports of lithium battery fires make headlines.

Natrion claimed that the new product, LISIC278, is a variation of Natrion's trademarked Lithium Solid Ionic Composite (LISIC) electrolyte made to mimic the precise requirements of a common polyolefin separator while using dramatically less liquid electrolyte. LISIC completes this by providing high ion transport capability at ambient problems while having a thermal durability in excess of 200 ° C and also being completely dense (zero porosity).

The result is a near-zero fire risk for batteries constructed with LISIC, as well as a dramatically reduced ability for a thermal event to intensify or broaden, says Natrion.

Alex Kosyakov, Co-Founder as well as Chief Executive Officer, Natrion, said, "Minimizing our dependence on flammable liquids in EV batteries is key to minimizing fire risk and ultimately making mass EV adoption much more viable. So the truth that this data reveals we can produce battery cells that are just as efficient with just a small portion of that liquid is a massive win."

Natrion claimed that it evaluated the new material over multiple regulated lab experiments making use of bag cells approximately 11 layers in thickness. In one regulated experiment, Natrion compared its LISIC278 against a common separator at the one-layer pouch level.

The control utilized was a basic pouch having NMC532 cathode, LP40 liquid electrolyte, as well as a natural graphite anode with a standard separator. The Natrion bag equaled yet used the LISIC278 separator instead of the conventional one.

LISIC278 Outcomes for Natrion:

Natrion cell took just 3 hrs to charge, compared to 5 hours for the conventional one at the same capacity which is a 40% boost.

The rapid fee time was coupled with just concerning 1/10th of the flammable liquid as the traditional cell.

High initial coulombic efficiency was also observed. Conventional Li-ion cells normally release less power than they are charged with throughout the initial few times that they are cycled which adds to permanent capacity loss (i.e. lower available energy or variety). Natrion cells showed higher first coulombic efficiencies and resultantly enhanced capacity retention at greater C-rates.

Altogether, the Natrion cell was able to deliver even more power at higher charge/discharge rates while using much less flammable material. Significantly, this was achieved using a solid electrolyte separator that is constructed to the exact very same specifications of existing separators, for rapid assimilation in present battery production procedures.

Natrion stated that it will be unveiling its outcomes for Lithium-anode information in the coming weeks.
