Solid Power, Inc. has entered a joint evaluation agreement with Samsung SDI and BMW Group to advance all-solid-state battery (ASSB) technology toward automotive commercialization. The collaboration focuses on developing and validating ASSB cells for use in a future demonstration vehicle.
Highlights
- Strategic alliance among Solid Power, Samsung SDI, and BMW to accelerate ASSB innovation.
- Sulfide-based solid electrolyte from Solid Power to be integrated into Samsung SDI cells for evaluation.
- Joint testing program to assess performance for potential vehicle integration.
- Objective: Commercialize ASSB technology with improved safety, energy density, and lifecycle performance.
Advancing All-Solid-State Battery Technology
Under the agreement, Solid Power will supply its proprietary sulfide-based solid electrolyte to Samsung SDI, which will integrate the material into separators or catholytes to build prototype cells. These cells will be tested against performance parameters jointly defined by Samsung SDI and BMW. The ultimate goal is to integrate these cells into a demonstration vehicle, showcasing the technology’s readiness for future electric vehicle (EV) platforms.
Solid Power President and CEO John Van Scoter said the collaboration “marks an important step toward widespread adoption of solid-state batteries,” emphasizing the stability and conductivity of the company’s electrolyte materials.
Strengthening Global Battery Partnerships
BMW’s Vice President of Battery Cell and Cell Module, Martin Schuster, highlighted that Samsung SDI’s inclusion “adds significant momentum” to the development pathway, reinforcing BMW’s strategy to remain at the forefront of advanced battery technologies.
Samsung SDI Executive Vice President Stella Joo-Young Go added that the company aims to “lead in commercialization of ASSB” through partnerships with Solid Power and BMW, underscoring the link between battery competitiveness and innovation in electric vehicles.
A Material-Driven Approach to Commercialization
Solid Power’s strategy centers on producing and selling its sulfide-based electrolyte to Tier 1 battery manufacturers and OEMs while licensing its cell designs and manufacturing processes. This model positions the company as a critical enabler in the transition from conventional lithium-ion to all-solid-state systems.
