Canadian battery maker Electrovaya is developing a solid state battery technology for heavy duty electric vehicles.

Electrovaya is developing a scalable and cost-effective lithium ion conducting ceramic for the solid state battery that has demonstrated good performance: ionic conductivity in the range of ~8.10-4 S/cm. Work continues to further improve conductivity and scale up of production.

The pouch cell battery under development also uses a a proprietary separator based on Electrovaya’s in-house ion conducting ceramic material. The separator incorporates a scalable manufacturing process and the company says it has made progress in increasing the separator size to meet the needs of commercially viable cells.

“Since early 2023, our team at Electrovaya Labs has made significant progress in the development of our solid-state battery separator and ion conducting ceramic materials. These materials form the backbone of our solid-state battery design and based on the progress to date, we are optimistic on a commercially viable solid state battery product,” said Dr. Raj DasGupta, CEO at Electrovaya.

“We are in discussions with one major automaker and are planning to send prototype samples of pouch cells later this calendar year.”

Electrovaya has two operating sites in Canada and has acquired a 52-acre site with a 135,000 square foot manufacturing facility in New York state for its planned gigafactory.
