Solid Power Warns of Electrolyte Production Delay

But solid state EV battery maker says development timeline unaffected despite production snag.

August 13, 2022

Solid Power, Inc. (SLDP) is developing an all-solid-state battery for electric vehicles (EVs) that replaces the liquid or gel polymer electrolyte used in conventional lithium-ion battery cells with a sulfide-based solid electrolyte. The company is in the process of building a second facility to expand its sulfide-based electrolyte production capabilities. Previously, Solid Power stated the facility would be brought online in the second half of 2022.

This timeline is no longer feasible.

In its latest quarterly filing, Solid Power blamed permitting and other issues for a delay in finishing the new facility which now, according to the company, won’t be running until sometime in the first quarter of 2023. Despite the delay, Solid Power says bringing the new facility online later than expected will not impact plans to deliver EV-scale cells to automotive original equipment manufacturers (OEMs) by the end of 2022:

“However, as of the date of this Report, we do not expect this delay to materially impact our development timeline.”
