Subsequent Events [Abstract]
Subsequent Event	Subsequent Event In April 2023, we entered into a lease agreement to lease approximately 774,000 square feet of premises in Brighton, Colorado and announced a plan to build a GWh-scale manufacturing facility in those premises. As of December 31, 2025, due to larger industry dynamics, particularly our ability to access global contract manufacturing to rapidly service the demand from our customers, we decided to terminate this lease. On January 30, 2026, we entered into an agreement with the lessor to terminate this operating lease facility in exchange for a one-time payment of $20.0 million. To account for the effect of the lease termination on our results of operations, we derecognize the related lease liability of $33.2 million and the remaining right‑of‑use asset of $13.3 million, and recorded a net loss on lease termination of approximately $0.1 million. The effects of the lease termination will be reflected in our consolidated condensed financial statements for the three months ending March 31, 2026.

In April 2023, we entered into a lease agreement to lease approximately 774,000 square feet of premises in Brighton, Colorado and announced a plan to build a GWh-scale manufacturing facility in those premises. As of December 31, 2025, due to larger industry dynamics, particularly our ability to access global contract manufacturing to rapidly service the demand from our customers, we decided to terminate this lease.

On January 30, 2026, we entered into an agreement with the lessor to terminate this operating lease facility in exchange for a one-time payment of $20.0 million. To account for the effect of the lease termination on our results of operations, we derecognize the related lease liability of $33.2 million and the remaining right‑of‑use asset of $13.3 million, and recorded a net loss on lease termination of approximately $0.1 million. The effects of the lease termination will be reflected in our consolidated condensed financial statements for the three months ending March 31, 2026.
