Solid Power has completed installation of its pilot production line for EV-scale solid-state silicon cells ready to qualify the battery cells for electric vehicle partners.

Solid Power intends to produce its sulfide-based silicon anode EV cells for internal testing before delivering cells to its automotive partners BMW and Ford to kick off automotive qualification testing, which is planned for the end of the year.

The pilot line is designed to mimic established lithium-ion manufacturing to reduce commercial risk and speed up production of the large format solid state cells for electric vehicles.

When running at full capacity, Solid Power’s EV cell pilot line is expected to be capable of producing 300 cells per week, or approximately 15,000 cells per year, with the majority of those being planned for automotive qualification testing.

By using over 50% active silicon in the anode, Solid Power has designed the cell for increased energy density, which is expected to correlate to longer driving range. It expects to be able to optimize its Silicon EV Cells for capacities ranging from 60 to 100 Ah for its automotive partners, while allowing for additional partners with distinct design specifications.

“Solid Power is encouraged by taking this next step on its automotive qualification roadmap,” said Doug Campbell, Chief Executive Officer of Solid Power. “The installation of this EV cell pilot line will allow us to produce EV-scale cells suitable for initiating the formal automotive qualification process. Over the coming quarters, we will work to bring the EV cell pilot line up to its full operational capability and look forward to delivering EV-scale all-solid-state cells to our partners later this year.”

“With the EV cell pilot line now installed, our next big challenge is commencing production at scale and building cells that meet the requirements necessary for us to enter into automotive qualification later this year,” said Derek Johnson, Chief Operating Officer at Solid Power.
