R&D Magazine has recognized Porous Power Technologies, LLC, for its ground-breaking work to improve the safety of the large-format lithium-ion batteries used in electric vehicles, low-profile consumer electronics, and high-power applications.
The award-winning product, Porous Power’s Symmetrix HPX-F ceramic-filled separator, is said by the company to significantly improves a battery’s thermal stability and reduces the risk of catastrophic cell failure.
Developed in collaboration with Oak Ridge National Laboratory and launched earlier this year, Symmetrix HPX-F also boosts cell performance and enables cells to cycle much longer than those with conventional separators.
“Instead of applying a dense ceramic coating to a separator, we thoroughly distribute ceramic particles throughout a highly porous, chemically inert PVDF polymer membrane,” explains Bernard Perry, Porous Power’s Chief Business Development Officer. “The particles reside primarily in the pore walls, leaving a large and uniform open-pore structure that enables ions to pass through with less resistance and less heat generation.”
According to the company, Symmetrix benefits include:
- Reduced likelihood of hard shorts
- More power in high-current applications
- Improved puncture and abuse resistance
- Far less separator shrinkage
- Increased thermal stability with less cell degradation
- Major improvement in cycle life performance
- Higher bake-out and operating temperatures
- Enhanced overall thermal stability
The R&D 100 Awards highlight “the 100 most technologically significant products introduced into the marketplace over the past year,” according to the magazine’s editors.
