Startup Liminal, which makes battery inspection systems for the manufacturing process, raised $17.5 million in its series A2 funding round, the company said Monday.
The Emeryville, Calif., company will use the funding to scale production of its EchoStat inspection system, which it bills as an automated factory-integrated system for testing the performance of EV batteries.
"Our products help battery manufacturers hit their aggressive production volume and cost targets while ensuring their cells meet stringent EV safety and performance requirements," said Liminal CEO and co-founder Andrew Hsieh.
ArcTern Ventures, a climate-focused venture capital fund based in Toronto, led the funding round. Liminal added two new investors in Northvolt, a Swedish battery developer and manufacturer, and the Ecosystem Integrity Fund.
Existing investors Chrysalix Venture Capital, Good Growth Capital, University of Tokyo Edge Capital Partners, Volta Energy Technologies, Impact Science Ventures and Helios Climate Ventures also contributed to this round.
