StoreDot has completed pack-level validation of its extreme fast charging (XFC) battery technology, confirming the system meets automotive industry requirements for thermal management, mechanical integrity, and safety. The milestone positions the silicon-dominant battery architecture for commercial vehicle integration.
Highlights
- StoreDot’s XFC battery completed pack-level testing for cooling, safety, and zero-swelling performance following 2,500 consecutive fast-charging cycles
- The battery technology supports a projected warranty exceeding 1 million kilometers (621,000 miles) with standard EV cooling systems
- B-sample cells are currently shipping to automotive partners for integration programs
- The “100-in-5” technology enables 100 miles of range from five minutes of charging
Validation Program Confirms Commercial Readiness
The pack-level validation program addressed three critical engineering requirements:
Thermal Management and Safety The battery system operates within thermal parameters compatible with existing production cooling infrastructure. StoreDot demonstrated this capability in the Polestar 5 integration. The cells hold UN 38.3 safety certification.
Mechanical Integrity Physical testing and analysis confirmed zero cell swelling across the cycle life. This characteristic eliminates concerns about pack dimensional changes that could compromise vehicle body integration or long-term durability.
Cycle Life Performance Testing documented over 2,500 consecutive XFC cycles. The data translates to battery warranty coverage beyond 1 million kilometers under fast-charging conditions.
Technology Development Timeline
StoreDot’s “100inX” product roadmap establishes specific charging speed targets:
- 100 miles charged in 5 minutes (2024)
- 100 miles charged in 4 minutes (2026)
- 100 miles charged in 3 minutes (2028)
The company developed its battery chemistry using proprietary organic and inorganic compounds. Artificial intelligence optimizes the material combinations.
Strategic Partnerships
StoreDot maintains development and investment relationships with BP, Daimler, VinFast, Volvo Cars, Polestar, Ola Electric, Samsung, and TDK. The company is actively shipping B-sample cells to partners for vehicle integration work.
