Summary
Solid Power (NASDAQ: SLDP) is a Louisville, Colorado solid-state battery developer that has pivoted toward a materials and electrolyte supply model rather than producing finished cells itself. The company makes sulfide-based solid electrolyte material and works with cell manufacturers — currently Samsung SDI — to build all-solid-state cells, which are then validated with automotive OEM partners. BMW i7 test vehicle integration was completed in 2025, and a three-way development collaboration with BMW and Samsung SDI was announced in October 2025. A continuous electrolyte production pilot line targeting up to 75 metric tons per year is planned for commissioning by end of 2026.

What It Is / How It Works
Solid Power’s business model is distinct from most solid-state battery companies. Rather than trying to become a vertically integrated cell manufacturer, the company focuses on its sulfide-based solid electrolyte as the core IP, licensing the technology and supplying electrolyte material to established cell manufacturers who already have the manufacturing infrastructure and automotive customer relationships.
In practice this means Solid Power makes the electrolyte, Samsung SDI builds the cells, and BMW validates them in vehicles. This approach has the advantage of not requiring Solid Power to build gigafactories — but it also means the commercialization timeline depends on Samsung SDI’s ability to integrate the electrolyte into production processes, which introduces a dependency that fully vertically integrated competitors like QuantumScape or Factorial Energy don’t have.
The October 2025 tripartite agreement with BMW and Samsung SDI is the clearest expression of this model: BMW provides the automotive development framework and test platform (the i7), Samsung SDI provides the cell manufacturing capability, and Solid Power provides the sulfide electrolyte and cell design IP.
The Ford JDA, which had been a secondary automotive partnership, is effectively winding down — the agreement expires March 31, 2026, after which Solid Power aims to pivot Ford to a material supply relationship rather than a joint development one.
