Solid Power Eyes 2027 Electrolyte Output, Korea JV to Scale Solid-State Batteries

Key Points

• Solid Power plans to commission its Colorado continuous-flow electrolyte line in late 2026 and begin production in early 2027. The expansion would increase site capacity from 30 to 75 metric tons and is currently on schedule and under budget.
• The company is pursuing a joint venture with a major Korean conglomerate, targeting up to 500 metric tons of electrolyte shipments in 2028 and potential long-term capacity of 20,000 metric tons.
• Solid Power expects to shift its revenue mix from collaboration payments toward electrolyte sales over the next one to two years, supported by relationships with BMW, Samsung SDI and SK On and growing interest from robotics, mining, aviation and defense markets.

Solid Power NASDAQ: SLDP said it is advancing a capital-light strategy centered on supplying sulfide solid electrolyte materials for all-solid-state batteries, while targeting increased production capacity, deeper partnerships and expansion into markets beyond electric vehicles.

During a JPMorgan discussion, the company said it has spent more than 15 years developing sulfide electrolytes, which it views as offering high ionic conductivity, manufacturability and a potential cost advantage versus other all-solid-state battery approaches. Solid Power said it has three generations of electrolyte materials available for customers and is using data, artificial intelligence and machine learning to support further product and manufacturing-process improvements.

The company said it held more than $400 million in cash equivalents as of the end of the prior quarter. Its business model is designed to avoid direct competition with Tier 1 battery manufacturers by focusing on electrolyte supply, technology development and partnerships rather than large-scale cell manufacturing.

Production Scale-Up Plans

Solid Power currently operates a 30-metric-ton batch production facility in Colorado and is completing a continuous-flow production line at the site. The company said all equipment for the project arrived during the second quarter and that construction and utility interconnect work is underway.

It expects to commission the continuous-flow line in the fourth quarter and begin production in the first quarter of 2027. The project is supported by a $50 million Department of Energy grant received in 2024, according to the company. Solid Power said the effort remains on plan and under budget.

Once operating, the Colorado site is expected to reach 75 metric tons of capacity. The company said its continuous manufacturing system should provide tighter process controls and more consistent output than its existing batch process. It has tested the underlying equipment and processes at a smaller pre-pilot scale through its Electrolyte Innovation Center.

Solid Power also said it is pursuing a joint venture with a large Korean conglomerate for the next stage of scale-up. The company aims to announce the partnership this year, begin design and construction next year, and potentially ship up to 500 metric tons of electrolyte to Korean and other global customers in 2028.

Over time, the company envisions expanding capacity with that partner to as much as 20,000 metric tons through the addition of 2,000-metric-ton production modules as demand develops.

Korea Partnership Rationale and Commercial Transition

Solid Power said it selected Korea for its next commercial-scale expansion because of the country’s battery ecosystem, including automotive manufacturers, Tier 1 battery producers, government support, national laboratories, technical talent and supply-chain infrastructure. The company also cited intellectual-property protection and the relationship between U.S. and Korean companies as considerations.

Management said the company expects to transition away from collaboration revenue and toward electrolyte sales over the next one to two years. Licensing is not expected to become a major portion of future revenue, a change from the company’s previous expectations, as it focuses more heavily on electrolyte supply.

The company said it intends to strengthen its commercialization and business-development teams over the next six to 12 months as spending on the Colorado continuous-flow project declines and capital needs for the prospective Korean joint venture rise.

Customer Collaborations and Technology Development

Solid Power highlighted relationships with BMW, SK On and Samsung SDI. BMW previously announced an all-solid-state battery module based on Solid Power-produced 60 amp-hour electric-vehicle cells that was integrated into a BMW i7 and driven in Munich under real-world conditions, according to the company.

The company said its recent three-way collaboration with BMW and Samsung SDI produced process improvements through rapid iterations between electrolyte development and cell-level validation. It expects the initial collaboration phase to evolve into separate agreements with BMW and Samsung SDI.

Regarding SK On, Solid Power said it successfully completed a line installation agreement and received a related milestone payment. The company said discussions are continuing around supporting SK On’s operation of that line as the battery maker matures its designs.

Solid Power said it continues to provide samples to multiple electric-vehicle original equipment manufacturers and has seen repeat sampling as customers refine cell designs. It said it can tailor electrolyte characteristics relatively quickly and hopes to announce additional partnerships, though it provided no details on potential counterparties or timing.

Markets Beyond EVs

While EVs remain its principal target, Solid Power said it is seeing growing interest from robotics, humanoid systems, mining, aviation and defense. Management characterized humanoid robotics as a particularly significant emerging opportunity because requirements for energy density, cycle life and safety overlap with EV applications.

The company said duty-cycle requirements remain an area to prove out for humanoid applications, and qualification periods could be comparable to EV timelines. Mining could represent a nearer-term opportunity, according to management, due to potential demand for safety and electrification benefits.

Solid Power said all-solid-state batteries could help address battery range, charging, safety and performance constraints as traditional liquid-electrolyte lithium-ion technology approaches its performance limits. It said lithium-metal, anode-less and high-purity silicon anode designs can be enabled by sulfide-based all-solid-state battery architectures.

Management said many industry participants are discussing initial production timelines around 2029, 2030 and the early 2030s. For Solid Power, it identified completion of its Colorado continuous-flow project, the Korean joint venture, ISO 9001 certification and additional partnerships as key milestones for investors to monitor.
