StoreDot, the pioneering Israeli firm specializing in extreme fast charging (XFC) battery technology for electric vehicles, has unveiled progress made in advancing its next-phase technology roadmap.
This progress builds upon the previously announced achievement of developing production-ready cells capable of delivering 100 miles (160 kilometers) in 5 minutes by the current year, with a target of achieving 100 miles in 3 minutes by 2028, as part of the company’s ongoing journey towards commercialization.
The advancements rely on a comprehensive set of design and engineering enhancements across the entire battery system rather than solely focusing on charging speed. StoreDot’s ‘100in4’ technology prioritizes increased energy density and a range of technological improvements. By adopting this holistic approach, the company aims to optimize real-world performance within existing charging infrastructure capabilities.
Specifically, StoreDot aims for at least a 10% enhancement in energy density compared to its 100in5 cells, enabling more mileage per charge at current charging rates. Achieving this involves optimizing various aspects of the battery, including chemistry, cell and pack engineering, cooling design, and internal connections modifications.
Regarding the ‘100in4’ technology, StoreDot reports achieving 1100 XFC cycles in a small form factor cell, projecting an energy density of 340Wh/kg in a large EV form factor. This milestone has been reached ahead of schedule, with the company continuing to refine its XFC technology towards producing cells capable of charging 100 miles in just 4 minutes by 2026.
The small form factor 100in4 prototype employs a 3Ah multi-layer battery cell with internal electrode layers similar to the larger battery cells StoreDot has already successfully scaled up for EV packs, demonstrating the scalability and maturity of the prototype cell.
According to Dr. Doron Myersdorf, CEO of StoreDot, “By adopting a balanced, system-level approach, we are unlocking the full potential of our XFC battery technology to maximize real-world performance. Rather than solely focusing on charging speed, our strategy prioritizes comprehensive technological enhancements across various aspects including energy density, cell and pack design, chemistry, and cooling optimization. This results in an extremely fast charging experience that can be seamlessly integrated into today’s infrastructure.”
“While this is an early prototype and challenges remain, our ability to swiftly scale up from a 3Ah to a >100Ah EV grade cell within months showcases our experience. We believe our roadmap offers a sustainable, practical, and proven path towards delivering extreme fast charging to drive mass EV adoption. We remain ahead of schedule for our planned milestones as we continue towards commercialization.”
StoreDot has recently announced anticipated milestones for 2024, including demonstrating the world’s first EV pack equipped with XFC technology, shipping prismatic B-samples to OEMs, and expanding its operations in the US.
The company remains on track for production-readiness of XFC cells capable of delivering 100 miles charged in 5 minutes by this year, 100 miles charged in 4 minutes by 2026, and 100 miles charged in 3 minutes by 2028.
StoreDot’s strategic investors and partners include BP, Daimler, VinFast, Volvo Cars, Polestar, Ola Electric, Samsung, TDK, and its manufacturing partner EVE Energy.
