Solid Power (SLDP) Q2 2025: BMW i7 Test Vehicle Validates Solid-State Progress, 75MT Electrolyte Expansion Targets Commercial Ramp
Solid Power’s Q2 marked a pivotal validation milestone as BMW debuted an i7 test vehicle powered by its solid-state battery cells, while SK-ON’s pilot line and a planned 75 metric ton electrolyte expansion signal a shift from R&D to early commercialization. Operating expenses rose with milestone-driven costs, but liquidity remains robust to fund the next phase. The company’s focus now turns to scaling customer sampling and securing long-term contracts as it approaches a critical inflection in technology deployment and revenue model transition.
Summary
- Automotive Validation Accelerates: BMW’s i7 test vehicle launch with Solid Power cells demonstrates real-world traction for its solid-state technology.
- Electrolyte Scale-Up Underway: Continuous pilot line expansion to 75 metric tons aims to support commercial sampling and future contracts.
- Capital Discipline Maintained: Strong liquidity and measured share repurchases fund growth while cushioning ongoing operating losses.
Performance Analysis
Solid Power’s Q2 results reflect an inflection from milestone-driven project revenue toward foundational commercial readiness. Revenue increased sequentially, driven primarily by the achievement of factory acceptance testing with SK-ON, a South Korean battery manufacturer, under the line installation agreement. This milestone is central to Solid Power’s strategy of licensing and supplying its proprietary sulfide electrolyte, a solid-state battery component that replaces traditional liquid electrolytes for improved safety and energy density.
Operating expenses rose, with $6.7 million attributed specifically to milestone execution, underscoring the cost intensity of scaling pilot lines and advancing customer partnerships. The company’s operating loss widened, but liquidity remains strong at nearly $280 million, providing ample runway for continued investment in technology, infrastructure, and customer engagement. Share repurchases, totaling $3.6 million this quarter, signal management’s confidence in the long-term value creation path despite ongoing net losses.
- Milestone Revenue Realization: Factory acceptance testing at SK-ON unlocked a significant portion of quarterly revenue, highlighting the importance of project-based milestones in the current business model.
- Cost Structure Shift: Operating expenses climbed as the company advanced both SK-ON and BMW programs, reflecting the transition from lab-scale R&D to pilot-scale manufacturing and customer validation.
- Liquidity Buffer: A robust cash position supports continued investment in pilot lines and commercial scaling, critical given the multi-year path to potential mass production contracts.
The quarter’s financials showcase a company still in investment mode, but with key signals that the business is approaching a commercial inflection point as automotive partners validate and scale pilot deployments.
Executive Commentary

Strategic Positioning
1. Automotive Validation Drives Commercial Credibility
The BMW i7 test vehicle powered by Solid Power’s solid-state cells provides third-party validation of the company’s technology in a real-world automotive context. This public milestone is likely to accelerate interest from other OEMs and supports the company’s positioning as a credible supplier in the next-generation EV battery market.
2. Electrolyte Production Scale-Up as Commercial Enabler
Investment in a continuous manufacturing pilot line for sulfide electrolyte at the SP2 facility—targeting 75 metric tons of annual capacity—signals a move from R&D to commercial readiness. This capacity is intended to support small-volume programs for both existing and new automotive and battery customers, laying the groundwork for future high-volume contracts.
3. Strategic Partnerships Anchor Technology Roadmap
SK-ON’s pilot line, designed and validated by Solid Power, and the ongoing partnership with BMW provide a dual-track strategy for technology deployment: licensing and electrolyte supply. These alliances de-risk the commercialization path and offer multiple monetization levers—direct product sales, technology licensing, and potential joint development agreements.
4. Capital Allocation Signals Long-Term Confidence
The decision to repurchase shares even while operating losses persist demonstrates management’s conviction in the technology’s long-term value and the company’s ability to reach commercial scale before cash reserves are depleted.
Key Considerations
This quarter’s developments place Solid Power at a strategic crossroads, with validation and scale-up activities setting the stage for the next phase of growth.
Key Considerations:
- OEM Validation Momentum: The BMW i7 test vehicle is a tangible proof point for Solid Power’s technology, likely to influence other automaker adoption decisions.
- Sampling and Customer Pipeline: Active electrolyte sampling with both new and existing customers is essential for converting technical milestones into recurring commercial revenue.
- Cost Discipline vs. Growth Investment: Operating expenses are rising as pilot lines and customer engagement scale, but liquidity remains sufficient to fund near-term objectives.
- Production Ramp Risks: The transition from pilot to continuous production at 75 metric tons is a critical execution risk and will determine the company’s ability to supply early commercial contracts.
Risks
Execution risk is elevated as Solid Power transitions from milestone-driven revenue to commercial-scale manufacturing and supply. Delays in pilot line commissioning, customer qualification, or unexpected technical hurdles could extend the path to profitability. The company’s reliance on a handful of strategic partners increases concentration risk, while sustained operating losses require continued capital discipline to avoid dilution or liquidity stress if commercialization lags.
Forward Outlook
For Q3 2025, Solid Power guided to:
- Completion of site acceptance testing for the SK-ON pilot line at customer facilities
- Continued ramp of electrolyte sampling and progress on customer pipeline development
For full-year 2025, management reiterated its commitment to:
- Commissioning the continuous electrolyte pilot line at SP2 in 2026
- Maintaining fiscal discipline while funding critical technology and infrastructure investments
Management highlighted several factors that will determine the pace of commercial ramp:
- Customer feedback and adoption rates from electrolyte sampling programs
- Timely completion and commissioning of new manufacturing infrastructure
Takeaways
This quarter marks a shift from proof-of-concept to early commercial readiness, underpinned by automotive validation and pilot line scaling.
- Pivotal OEM Validation: BMW’s i7 test vehicle puts Solid Power’s solid-state technology on the automotive map, increasing the likelihood of broader OEM adoption.
- Execution Pathway: Success now depends on timely completion of pilot lines and conversion of sampling into long-term contracts, with cost discipline as a critical guardrail.
- Watch for Commercial Traction: Investors should track customer sampling conversion, pilot line commissioning milestones, and any new OEM or battery maker partnerships as leading indicators of revenue inflection.
Conclusion
Solid Power’s Q2 demonstrates tangible progress toward commercializing solid-state battery technology, with validation from BMW and SK-ON signaling industry confidence. The company’s ability to scale electrolyte production and convert sampling into recurring contracts will determine whether it can bridge the gap from milestone revenue to sustainable growth.
Industry Read-Through
Solid Power’s progress underscores accelerating OEM interest in solid-state batteries as the next major leap in EV performance and safety.
