Solid Power aims to send first solid-state battery cells to BMW, Ford by year’s end

Solid Power, a developer of solid-state batteries for electric vehicles, aims to begin shipping pre-production battery cells by the end of the year for validation testing.

Solid Power, a developer of solid-state batteries for electric vehicles, aims to begin shipping pre-production battery cells by the end of the year for validation testing by partners BMW and Ford Motor, the company said on Monday.

In an interview, Solid Power’s chief executive and co-founder, Doug Campbell, said that the Colorado company will begin production of its cells in early 2026 while seeking a manufacturing partner to provide validation samples to automakers. A pilot production line is established.

One potential partner, he said, is Korea’s SK Innovation, which is building joint venture battery plants with Ford in Tennessee and Kentucky.

“Long-term, we don’t strive to be a cell manufacturer,” he said.

Campbell said Solid Power has enough pilot production capacity to provide prototype battery cells to other automakers, but declined to provide specific details.

The company, which went public in 2021 through a reverse merger, attracted early investments from Hyundai and Samsung, in addition to Ford and BMW.

Campbell acknowledges the “intense competition in solid-state battery development among the big boys — groups such as Toyota, Panasonic, Samsung, LG Energy Solutions, Hyundai and CATL.”

“We are in a position among very prominent and reliable players,” he said.

Like most of those companies, Solid Power’s battery cell consists of a sulfide-based solid-state electrolyte, through which lithium ions flow between the positive and negative electrodes during charging and discharging.

Battery cells with solid-state electrolytes have a significantly lower risk of fire from internal shorts than do liquid electrolytes.

Campbell said Solid Power’s cells, which currently use a silicon-rich anode and a nickel-cobalt-manganese cathode, have the potential to hold more energy — thus providing electric vehicles with longer ranges — and compared to conventional ones. Lower cost than lithium-ion batteries.

Solid Power has designed its solid-state cell to be compatible with current lithium-ion manufacturing processes.
