• Automated pilot production line designed to produce EV-scale sulfide-based all-solid-state battery cells now installed
• Expect to deliver Silicon EV cells to automotive partners by year end to commence qualification testing
• Pilot production line purpose-designed to mimic established lithium-ion manufacturing to reduce commercial risk

Solid Power, Inc. ("Solid Power") (Nasdaq: SLDP), an industry-leading developer of all-solid-state battery cells for electric vehicles, today announced that it has completed installation of its pilot production line – dubbed the “EV cell pilot line” – which is designed to produce EV-scale solid-state cells. Solid Power intends to produce Silicon 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.

“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.”

Solid Power’s EV cell pilot line is designed to produce large-format sulfide-based cells in a manner that mimics existing traditional lithium-ion production processes. 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.

Solid Power’s Silicon EV Cells are designed to power longer-range, lower-cost and safer electric vehicles. 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 ranges to address range anxiety – a key barrier to mass EV adoption.

“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.

Solid Power expects to be able to optimize its Silicon EV Cells for capacities ranging from 60 to 100 Ah. The company expects this flexibility to allow Solid Power to meet its automotive partners’ specifications, while allowing for additional partners with distinct design specifications.

About Solid Power

Solid Power is an industry-leading developer of all-solid-state rechargeable battery cells for electric vehicles and mobile power markets. Solid Power replaces the flammable liquid electrolyte in a conventional lithium-ion battery with a proprietary sulfide-based solid electrolyte. As a result, Solid Power's all-solid-state battery cells are expected to be safer and more stable across a broad temperature range, provide an increase in energy density compared to the best available rechargeable battery cells, enable less expensive, more energy-dense battery pack designs and be compatible with traditional lithium-ion manufacturing processes.
