Electrovaya-Litarion Introduces SEPARION P20 — New, Thinner Flexible Ceramic Separator For Lithium-Ion Batteries

The SEPARION P20 — a new, thinner flexible ceramic separator for lithium-ion batteries used in utility-scale and electric vehicle applications — was recently introduced by Electrovaya Inc and its wholly owned subsidiary, Litarion GmbH, according to recent reports.

The new flexible ceramic separator introduction means that the SEPARION line of products now includes both the nominal 21 micron (P20) and the 28 micron (P30) separators.


Green Car Congress provides more:

SEPARION withstands unusually high temperature incursions, thus making a lithium-ion battery safer. SEPARION has been used in more than two million large-format lithium ion cells powering advanced applications such as electric vehicles and grid-scale energy storage. The newly launched P20 now enables the same SEPARION technology to be used in a thinner format. P20 is being qualified with several customers with very positive results, according to the company.

In addition to its safety advantages, the SEPARION family of flexible ceramic separators also increases the cycle-life of lithium ion batteries. The extended cycle life can change the cost equation as the SEPARION enables lithium-ion cells to have a lower cost per cycle.

On that note, we’ve been covering Electrovaya-Litarion a fair amount lately, as some interesting developments have been occurring… Those interested in reading more about those developments can do so here: Electrovaya & Litarion Unveil New 40 Ah Lithium-Ion Battery Cell.

The company certainly seems to be one to watch, with consistently interesting developments seemingly occurring regularly. Though predicting which companies/developments will end up panning out over the long run is, as always, not an exact science — so maybe I’m mistaken in my interest. 🙂
