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

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.

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.

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.
