Solid Power, Inc.

Solid Power, Inc. (SLDW: The Stock Market LLC) is a U.S.-based developer of solid-state battery technology and manufacturing processes headquartered in Colorado. The company operates through its website at www.solidpowerbattery.com and focuses on sulfide-based solid electrolyte materials designed to replace the liquid or gel electrolytes used in traditional lithium-ion battery cells.

The company's core technology centers on manufacturing sulfide-based solid electrolytes comprised of lithium sulfide and other inputs. Solid Power's business model emphasizes electrolyte production and licensing of cell manufacturing processes rather than direct battery cell manufacturing, allowing the company to maintain lower capital requirements than traditional cell manufacturers. The electrolyte is engineered to enable improvements in energy density, battery life, and safety performance compared to conventional lithium-ion batteries, with particular application in battery electric vehicles.

Solid Power operates pilot manufacturing lines for both electrolyte and solid-state cells. The company produces electrolyte using batch manufacturing processes and expects to commission a continuous manufacturing pilot line by the end of 2026, designed to expand annual production capacity to approximately 75 metric tons. The company manufactures solid-state cells in sizes ranging from 0.2 ampere-hours to 60 ampere-hours using multi-layered stacked pouch designs with nickel manganese cobalt oxide cathodes and silicon-based anodes.

As of February 1, 2026, Solid Power employed approximately 230 employees, primarily based at facilities in Louisville and Thornton, Colorado. The company maintains strategic partnerships with major automotive and battery manufacturers including BMW Group, Samsung SDI, SK On, and Ford Motor Company. These non-exclusive partnerships focus on joint development, technology licensing, and electrolyte supply arrangements.

Solid Power's intellectual property portfolio includes 24 issued United States patents, 100 pending U.S. patent applications, and 111 non-U.S. and PCT patents and applications as of February 1, 2026. The company also holds exclusive licenses from the University of Colorado Boulder and Oak Ridge National Laboratory. In January 2025, Solid Power secured a $50 million grant from the U.S. Department of Energy under the Bipartisan Infrastructure Law to support electrolyte production expansion.
