Electrovaya’s Acquisition Of Evonik Litarion GmbH Complete, Along With Licensing Of SEPARION Intellectual Property

The noted Canadian lithium-ion battery developer/manufacturer Electrovaya has completed its acquisition of Evonik Litarion GmbH — along with completing the licensing process for the “SEPARION” ceramic composite separator — according to a recent press release.

The completion of the process means that Evonik Litarion’s automated lithium-ion electrode + ceramic composite separator production plant — with a rated production capacity of half a gigawatt-hour (GWh) of electrodes, and 10 million m2 of ceramic separators — is now under the control of Electrovaya. Accompanying this is the transfer of associated intellectual property rights as well, of course.


This acquisition gives Electrovaya a stronger manufacturing base, potentially allowing the company to win larger energy storage contracts.

The Chairman and CEO of Electrovaya, Dr Sankar Das Gupta, commented on the acquisition: “Conventional manufacturing of lithium ion employs a toxic NMP (n-methyl-pyrrolidone) process, which is prohibitively expensive and energy intensive. Regulations are becoming more stringent in Japan, Europe, and North America. Electrovaya’s unique non-toxic manufacturing technology will enable this best-in-class plant to become one of the lowest cost producers, as well as the greenest and one of the largest manufacturers globally. We are delighted to be working with an exceptional and experienced team at Litarion.”

“We also intend to make the ceramic composite separator available to all producers of lithium-ion batteries and make it an industry standard. All lithium-ion applications where safety is important such as energy storage, electric vehicles, aerospace, and utilities, should, in our opinion, utilize this separator which gives vastly improved safety performance to lithium-ion batteries and cells. Electrovaya’s proprietary green process provides low cost lithium-ion batteries and this ceramic composite separator affords the highest safety, two critical challenges in the energy storage industry.”

For a bit of background here — SEPARION is, essentially, just a proprietary ceramic composite separator intended for use in “ultra-safe” lithium-ion battery applications.

Worth noting here, is that the acquisition provides Electrovaya with an exclusive distribution license; along with the option to sub-license, expand production, create new manufacturing plants, or form joint ventures involving the technology.
