Israeli battery developer StoreDot has announced a strategic partnership with South Korean battery manufacturer Kumyang to mass-produce cylindrical electric vehicle (EV) battery cells featuring its groundbreaking Extreme Fast Charging (XFC) technology. Under this agreement, Kumyang will license StoreDot’s XFC technology and integrate it into its cylindrical battery production lines, with a primary focus on the large-format 4680 family.
The partnership marks a significant milestone for StoreDot as it expands its XFC battery offerings beyond prismatic and pouch cells into the highly sought-after cylindrical format. This move is expected to accelerate the global adoption of ultra-fast charging EVs, reducing charging times dramatically while maintaining high energy density and long battery life.
XFC Technology: 10-Minute Charging for EVs
StoreDot’s XFC technology has been developed to address one of the biggest challenges in EV adoption—charging time. Traditional lithium-ion batteries require anywhere from 30 minutes to several hours to charge fully. However, StoreDot’s XFC cells can charge from 10% to 80% in just 10 minutes, bringing the EV charging experience much closer to the convenience of refueling a gasoline vehicle.
Previously, StoreDot showcased this revolutionary technology in a prototype of the Polestar 5, proving that ultra-fast charging is achievable with the right battery chemistry and design. The partnership with Kumyang now takes this innovation from the prototype stage to mass production.
Kumyang’s Role in Scaling XFC Battery Production
Kumyang, a leading South Korean battery manufacturer, will play a crucial role in scaling up the production of XFC cylindrical batteries. The company will implement StoreDot’s XFC technology in its manufacturing processes, focusing on the 4680 and 4695 battery formats.
The 4695 format has already demonstrated impressive initial results, boasting a lifespan of over 1,000 charge cycles at standard charge rates. Additionally, these batteries feature a volumetric energy density exceeding 800 Wh/L, making them a game-changing solution for EV manufacturers looking to balance high performance with ultra-fast charging.
StoreDot CEO Dr. Doron Myersdorf emphasized the importance of this milestone, stating:
“This license agreement with Kumyang is a pivotal step towards making XFC technology accessible to key EV OEMs awaiting our XFC technology in cylindrical format. Ultimately, this will enable drivers to spend less time charging and more time on the road.”
Kumyang CEO Ryu Kwanghyun echoed this sentiment, adding:
“We are incredibly excited to integrate StoreDot’s revolutionary XFC technology into our 4680 cylindrical cell production. This collaboration aligns perfectly with our commitment to delivering cutting-edge battery solutions that empower the widespread adoption of electric vehicles.”
Why Cylindrical XFC Batteries Matter
Cylindrical battery cells, particularly the 4680 format, have gained significant traction in the EV industry due to their:
- Higher Energy Density: More energy storage per unit volume
- Better Thermal Management: Improved cooling efficiency
- Manufacturing Scalability: Easier to produce at a large scale
- Cost-Effectiveness: Lower production costs compared to pouch or prismatic cells
Tesla, Panasonic, and LG Energy Solution have all invested heavily in 4680 battery technology, making it one of the most anticipated battery formats for next-generation EVs. StoreDot’s XFC-enhanced version of the 4680 cell will further push the envelope by offering ultra-fast charging without compromising energy density or longevity.
Advancing Global EV Adoption Through Faster Charging
Reducing EV charging time is critical for the widespread adoption of electric mobility. Long charging durations have been one of the biggest pain points for consumers, limiting the practicality of EVs for long-distance travel and daily use. By reducing charging time to just 10 minutes, StoreDot’s XFC technology could eliminate range anxiety, making EVs far more appealing to a broader market.
Additionally, StoreDot’s XFC technology doesn’t compromise battery lifespan—a common trade-off with fast-charging solutions. By ensuring that XFC batteries last over 1,000 cycles, StoreDot provides both fast charging and long-term durability, making EV ownership more sustainable and cost-effective.
StoreDot’s Expanding Global Partnerships
This partnership with Kumyang is part of StoreDot’s broader global expansion strategy. In February, StoreDot announced a joint venture with JR Energy Solution, another South Korean battery technology company, to mass-produce ultra-fast charging batteries.
StoreDot also has an impressive network of strategic investors and partners, including:
- BP (energy solutions)
- Daimler (automotive)
- VinFast (EV manufacturer)
- Volvo Cars & Polestar (automakers)
- Ola Electric (electric mobility)
- Samsung & TDK (battery technology and electronics)
By collaborating with major global players, StoreDot is positioning itself as a leader in ultra-fast charging technology, ensuring that its XFC batteries reach mainstream adoption across multiple industries.
What This Means for the Future of EVs
The StoreDot-Kumyang partnership could have major implications for the EV industry, especially in the following ways:
- Faster Charging, Better EV Adoption – The ability to charge in 10 minutes makes EVs far more practical for consumers.
- Increased Investment in Fast-Charging Infrastructure – As fast-charging batteries become mainstream, the need for high-powered chargers will grow.
- Cost Reductions Over Time – Mass production of XFC batteries will drive down costs, making fast-charging EVs more affordable.
- Competitive Advantage for Early Adopters – Automakers using StoreDot’s XFC batteries could gain a significant edge in the market.
Conclusion
The partnership between StoreDot and Kumyang represents a major leap forward in battery technology, bringing ultra-fast charging to cylindrical EV batteries for the first time. As the world shifts towards electrification, innovations like XFC technology will play a crucial role in making EVs more convenient, efficient, and accessible to the masses.
With 4680 and 4695 cylindrical XFC cells set for mass production, EV manufacturers will soon have access to batteries that charge in 10 minutes, last over 1,000 cycles, and deliver industry-leading energy density.
As StoreDot continues expanding its global partnerships, the company is shaping the future of electric mobility—one ultra-fast charge at a time.
