Solid Power develops and produces all-solid-state battery cells for electric vehicles. Its batteries use sulfide-based solid electrolytes that combine high ionic conductivity with the ability to be manufactured defect-free on standard roll-to-roll battery production equipment, enabling batteries that are safer, lighter, and capable of higher energy density. This makes Solid Power’s packs potentially cheaper and longer-lasting, differentiating it from traditional lithium-ion systems that rely on liquid electrolytes and more complex manufacturing steps. The company collaborates with automakers such as BMW and Ford and partners like SK Innovation, aiming to scale automotive-scale production. Its goal is to help enable longer-range, lower-cost, and safer EVs through solid-state battery technology.

Simplify's Take
What believers are saying
- Trilateral validation with Samsung SDI and BMW accelerates all-solid-state battery commercialization for next-gen EVs by 2027.
- Capital-light model reduces risk versus rivals building full-scale battery plants while securing major OEM partnerships.
- Completed SK On pilot line testing enables production across Colorado, Germany, and South Korea, confirming global readiness.
What critics are saying
- Samsung SDI developing its own sulfide electrolyte pilot line in 2024 eliminates reliance on Solid Power by 2027.
- Q1 2026 revenue decline of 50% signals unsustainable cash burn risking dilution if commercialization lags within 12 months.
- Business model extinction risk if major partners like Samsung SDI fully integrate electrolyte production within 24–36 months.
What makes Solid Power unique
- Solid Power sells sulfide electrolyte and licenses designs instead of manufacturing full battery cells.
- Its sulfide-based electrolyte offers superior conductivity and roll-to-roll processability compared to other solid-state approaches.
- The company enables $50M DOE-funded continuous production to become the leading global sulfide electrolyte supplier.

↑ 0%Solid Power has entered a Joint Evaluation Agreement with Samsung SDI and BMW to validate its electrolyte sampling efforts and advance all-solid-state battery development. The company also completed detailed design and factory acceptance testing for a continuous electrolyte production pilot line, scheduled for installation by the end of 2026 under its agreement with SK On. For full year 2025, Solid Power spent $84.5 million in total cash, near the lower end of its $85–$95 million forecast. Revenue reached $21.7 million, primarily from the SK On agreement, whilst operating expenses totalled $122.6 million, resulting in a $93.4 million net loss. The company ended 2025 with $336.5 million in total liquidity. For 2026, Solid Power expects to invest between $85 million and $100 million whilst advancing commercial-scale production.

Solid Power has entered a securities purchase agreement with a single institutional investor for a registered direct offering worth $130 million. The offering includes 17 million common shares, pre-funded warrants for 5.81 million shares, and common warrants for up to 45.61 million shares. The deal involves a sector-focused institutional investor, though the company did not disclose additional details about the investor's identity or the specific terms of the warrants.
Samsung SDI, Solid Power, and BMW to collaborate on solid-state batteries. South Korean battery manufacturer Samsung SDI has signed an agreement with the BMW Group and US solid-state battery specialist Solid Power to collaborate on a validation project for pure solid-state batteries. Under this agreement, Samsung SDI will supply solid-state cells that use a solid electrolyte developed by Solid Power and are said to "offer improved energy density and safety," according to the announcements. BMW will develop modules and packs for the solid-state cells. The agreement explicitly refers to "modules and packs," although BMW is relying on cell-to-pack technology without modules for its new class of electric cars. However, the cell-to-pack battery in the new iX3 uses round cells. Samsung SDI's All-Solid-State Battery (ASSB), on the other hand, uses prismatic cells. And BMW uses prismatic cells in its electric cars based on the CLAR platform, for example. Back in May, BMW itself announced that it would be testing Solid Power's solid-state cells in an i7. While the i7 mentioned above still used pilot cells from Solid Power, which were manufactured on a very small scale, the current tests with Samsung SDI also involve a larger battery manufacturer. This means that the focus is no longer on functional tests of pure prototype batteries, but on cells that have been manufactured by a large-scale manufacturer with a view to further commercialisation. BMW has been using Samsung SDI batteries since 2009. The three partners intend to evaluate the performance of the solid-state cells based on the agreed parameters and requirements and integrate them into BMW's next-generation evaluation vehicles, according to the announcements. The collaboration is significant "in that the three specialised companies have established a practical collaboration system and a model for global value chains for ASSB cells, aiming to pave the way for their commercialisation by bringing together their complementary expertise in cells manufacturing, automaking and materials development." BMW and Solid Power have been working together on solid-state batteries for years. Their partnership dates back to 2016. Things got serious three years ago when both sides signed a technology transfer agreement. BMW's partnership with Samsung SDI dates back to 2009, when the Koreans were selected by BMW as a battery supplier. Until now, however, Samsung SDI has pursued its solid-state activities independently, and it is only now that the three companies are officially working together in this area. Back in 2024, the South Koreans announced their intention to start mass-producing solid-state cells in 2027. "Technological competitiveness in batteries would ultimately lead to innovations in electric vehicles," says Stella Joo-Young Go, Executive Vice President of the ASSB Commercialization Team at Samsung SDI. "Samsung SDI will work closely with strategic partners such as BMW and Solid Power to take the lead in commercialization of ASSB." "With Samsung SDI joining our partnership with Solid Power, we gain significant momentum on our path advancing the development of new battery cell technologies," adds Martin Schuster, Vice President Battery Cell and Cell Module at the BMW Group. "This global collaboration is another proof point of our overarching goal: to be always in a position to offer our customers state of the art battery technology." "We are excited to partner with SAMSUNG SDI and BMW to progress the development of all-solid-state batteries," comments John Van Scoter, President and CEO of Solid Power. "Our solid electrolyte technology is designed for stability and conductivity, and by working closely with global leaders in automotive and battery innovation, we strive to bring ASSB technology closer to widespread adoption." 0 comments. about "Samsung SDI, Solid Power, and BMW to collaborate on solid-state batteries"
