StoreDot has made its commercial-ready 4695 cylindrical cells available for testing by global defense and aerospace contractors. The Israeli company, known for its silicon-dominant anode technology in the automotive sector, is now targeting tactical applications for drones and unmanned ground vehicles (UGVs).
The 4695 form factor measures 46mm in diameter and 95mm in height. StoreDot designed the cells to eliminate charging downtime in mission-critical operations.
Highlights
- 10-minute charging: Cells charge from 10% to 80% in 10 minutes, supporting rapid turnaround for unmanned systems.
- High energy density: The cells deliver 800Wh/L and 280Wh/kg for extended endurance in compact form factors.
- 2,000+ cycle durability: Validated for over 2,000 consecutive XFC cycles, reducing field replacement frequency.
- Cold-weather performance: Maintains 80% charge capability at -10°C (14°F) for arctic and high-altitude missions.
Performance Specifications
StoreDot’s 4695 cells target what the defense industry calls the “logistical tail” of electrified platforms. The specifications address key operational requirements:
- Extreme Fast Charging (XFC): 10% to 80% state of charge in 10 minutes
- Volumetric Energy Density: 800Wh/L
- Gravimetric Energy Density: 280Wh/kg
- Cycle Life: 2,000+ consecutive XFC cycles
- Low-Temperature Operation: 80% charge capability at -10°C (14°F)
NDAA Compliance and Supply Chain Considerations
StoreDot positions its technology as compliant with emerging U.S. and allied procurement mandates aimed at reducing dependence on Chinese battery manufacturers.
Section 154 Compliance
The company’s silicon-dominant chemistry offers an alternative to Chinese-manufactured lithium-ion batteries from companies like CATL and BYD. The FY2024 NDAA Section 154 procurement ban takes effect in October 2027.
1260H List De-risking
StoreDot has prioritized Western-aligned manufacturing partnerships, including Kumyang in South Korea. This approach helps defense OEMs avoid reliance on entities identified on the Section 1260H list of Chinese Military Companies.
Section 842 Readiness
The 4695 cell supply chain is being structured to meet NDAA FY2026 Section 842 requirements. This section prohibits procurement of advanced batteries and components from adversaries.
Target Applications
StoreDot has identified three primary defense use cases for the 4695 cells:
- Persistent UAS/UAVs: Near-continuous flight operations with rapid ground-station charging
- Tactical UGVs: Extended sensor-payload endurance and reduced thermal signature
- Silent Watch and Land Systems: High-power discharge for electronic warfare and rapid charging during tactical pauses
Company Background
