On 26 October 2026 the company started commissioning MOBIUS, a continuous‑manufacturing pilot line at its SP2 facility in Thornton, Colorado, intended to increase annual solid‑electrolyte output by roughly 150 percent.

Construction has reached substantial completion, materials are already feeding the line and primary powder‑processing equipment has passed site‑acceptance testing.

Full equipment testing is slated for completion by the end of October, with plant validation and operational start‑up planned for the fourth quarter of 2026.

MOBIUS adds an additional 45 metric tons of designed capacity, bringing the SP2 site’s total annual electrolyte capacity to approximately 75 metric tons once commissioning is finished.

The line is a pilot‑scale operation; while the capacity figure marks a manufacturing milestone, it does not yet guarantee commercial‑grade volumes, pricing or consistency required for mass‑market electric‑vehicle batteries.

Solid Power’s business model focuses on supplying sulfide‑based solid electrolyte and licensing cell designs rather than building complete battery packs, a strategy reflected in the purpose of MOBIUS.

The company receives up to $50 million in U.S. Department of Energy assistance for the project, part of a broader effort to develop domestic advanced‑battery material capabilities.

Solid Power reported $419.3 million in liquidity and no debt at the end of June 2026, though it posted a $23.8 million net loss in the second quarter, underscoring that financial strength does not yet equate to profitability.

The next critical step is to complete commissioning, validate the line’s performance, and produce electrolyte that meets partner specifications, which will determine whether the pilot can translate into sustained commercial demand.
