StoreDot’s XFC Shield Strengthens IP Portfolio for Extreme Fast-Charging

On July 7, 2025, StoreDot, the world leader in extreme fast charging (XFC) battery technology for electric vehicles (EVs), announced a major expansion of its intellectual property portfolio. The company has been granted one new U.S. patent and received Notices of Allowance for two additional key patent applications, signaling their imminent issuance. Together, these patents form critical pillars of StoreDot’s XFC Shield™ framework, further cementing its dominant position in silicon-based anode technology for fast-charging applications.

The newly granted US Patent No. 12,261,324, along with allowed applications US 18/604,017 and US 18/604,062, represent groundbreaking advancements that address core challenges of silicon anodes—most notably swelling and cycle life degradation. These innovations are essential to making extreme fast charging a practical reality in lithium-ion batteries, unlocking the potential for EVs to gain hundreds of miles of range in just minutes.

This strengthened IP position provides StoreDot with a powerful defensive moat, effectively blocking other entities from leveraging silicon or silicon-carbon composites as primary active materials in EV anodes for extreme fast charging. With these patents, StoreDot secures a decisive competitive advantage and underscores its commitment to driving mass EV adoption.

“This is a critical milestone for the EV industry. Any company aiming to deliver fast-charging EV batteries using silicon or silicon-carbon composite should consider obtaining a license from StoreDot,” said Dr. Doron Myersdorf, CEO of StoreDot.

StoreDot’s leadership in XFC technology directly tackles two of the biggest obstacles to widespread EV adoption: range anxiety and long charging times. By enabling rapid charging comparable to refueling a gasoline car, StoreDot’s innovations promise to transform the EV ownership experience and accelerate the transition to clean transportation.

StoreDot invites industry stakeholders to recognize the breadth and strength of the XFC Shield™ framework and encourages companies working on silicon-dominant fast-charging battery technology to engage in licensing discussions.

A Polestar 5 Prototype Equipped With Storedot’s XFC Cells Was Charged From 10% to 80% in 10 Minutes

In May 2024, StoreDot and Polestar completed a landmark demonstration. Since introducing its extreme fast charging (XFC) silicon-dominant EV battery cells, StoreDot has received overwhelmingly positive feedback for its tested cells. In a groundbreaking demonstration—the world’s first 10-minute charge of an EV equipped with a standard 77 kWh battery pack powered by silicon-based technology—StoreDot showcased the transformative potential of its innovation. In collaboration with Polestar, this milestone directly addresses one of the biggest barriers to EV adoption, the length of charging time. This demonstration was significantly faster than the average time to charge an EV from 10%-80%.

“The challenge of this demonstration lies in the integration of StoreDot’s XFC technology with the existing design of the Polestar 5, requiring no modifications to the vehicle’s architecture or peripheral systems,” said Dan Corfas, Director of Product and System Engineering at StoreDot. “The integration effort had to solve all mechanical, electrical, thermal and software challenges to produce a battery that can charge in 10 minutes, while maintaining the environment needed for the cells’ longevity and safety. We had many challenges during the project, and together with the amazing team at Polestar we had to creatively work through them all. Our cells were designed with this simplified, almost ‘drop-in’ approach, this is also true on the manufacturing side where our technology has full compatibility to standard production lines”.

Jens Groot, Battery System Chief Engineer at Polestar, reflected on the project from the automaker’s perspective: “What we did this month is, I believe, a world first. For a standard vehicle without any novel cooling systems, we are looking at charging speeds I haven’t seen anywhere else. We reached consistent speeds of 310-380 kW. This is proof that we can now charge at these speeds in a standard car. We didn’t add anything new outside the battery pack. It still had the original cooling pump and fan,” he says of the prototype Polestar 5. “With this battery, it almost doesn’t matter when you stop to charge your car. Whether you stop to recharge at 10 percent or 60 percent, you’ll achieve the same speeds. In this sense, the experience is more like filling up your car at the petrol station.”

EVinfo.net’s Take: EV Tech Is Moving Fast, StoreDot’s 10-Minute Charge on a Polestar Proves It

The electric vehicle (EV) world is evolving at lightning speed, and one of the biggest hurdles—slow charging times—is finally being overcome. StoreDot and Polestar’s demonstration was an important breakthrough for reducing charging time. Through this achievement, StoreDot and Polestar are paving the way for a new era of electric mobility that is more convenient, accessible, and appealing to a broader audience.

Yesterday, EVinfo.net reported on a new Guinness World record for EV range. webCG Inc. set a remarkable new Guinness World Record by driving an electric vehicle (EV) an astounding 1,045 km (649 miles) on a single charge. The record-setting journey took place between Wednesday, June 18, and Thursday, June 19, 2025, using a Mercedes-Benz EQS 450+.

EV ranges are increasing, and battery recharging times are decreasing. In March 2025, China’s BYD unveiled its new “super e-platform,” capable of delivering peak charging speeds of up to 1,000 kilowatts (kW), enabling EVs that are equipped with it to charge for 5 minutes and travel up to 400 kilometers (249 miles).

Range anxiety, the fear of EV drivers running out of charge on the road, and recharging time are two of the largest barriers to mass EV adoption. Both of these barriers are being torn down rapidly, as these amazing advancements show.

With solutions like StoreDot’s XFC technology on the horizon, the future of electric vehicles has never looked brighter—or faster. Our transportation future is electric, and innovations like these bring that reality closer and closer every day.
