StoreDot’s 100in4 XFC prototype cells

StoreDot, revealed progress made on the development of its next-phase roadmap for extreme fast charging (XFC) battery technology.

StoreDot is an Israelian company pioneer and world leader in extreme fast charging (XFC) battery technology for electric vehicles.

This builds on its previously announced introduction of production-readiness cells capable of 100 miles in 5 minutes this year, and 100 in 3 minutes by 2028, as the company continues its path towards commercialization.

This advancement relies on a suite of holistic design and engineering upgrades to the entire battery system, rather than focusing purely on charging speed.

StoreDot’s ‘100in4’ technology prioritizes increased energy density and a myriad of technological enhancements. By taking this system approach, the company aims to maximize real-world performance with the available charging infrastructure.

Specifically, StoreDot is targeting at least a 10% improvement in energy density compared to its 100in5 cells. This will enable more mileage from a charge with the existing charging rates.

The key to achieving this is optimizing multiple aspects of the battery, including chemistry, cell and pack engineering, cooling design, and modifications to internal connections.

For the ‘100in4’ technology, StoreDot has already achieved 1100 XFC cycles in a small form factor cell, with projected energy density of 340Wh/kg in a large Electric Vehicle form factor. This milestone comes earlier than planned, and the company will continue refining its XFC technology on the path to production-ready cells that deliver 100 miles charged in just 4 minutes by 2026.

The small form factor 100in4 prototype utilizes a small capacity (3Ah) multi-layer battery cell with internal electrode layers similar to the larger battery cells StoreDot already has proven and scaled up for EV packs, show the scalability and maturity of the prototype cell.

Dr Doron Myersdorf, CEO StoreDot

By taking a balanced, system-level approach, we are unlocking the full potential of our XFC battery technology to maximize real-world performance. Rather than prioritizing charging speed, our plan focuses on technological enhancements across the board – energy density, cell and pack design, chemistry, and cooling optimization. The result is an extremely fast charging experience that can be easily deployed on today’s infrastructure.

While this is an early prototype and there are still challenges to overcome, we can draw from our experience of seamlessly scaling up from a 3Ah to a >100Ah EV grade cell within months. We believe our roadmap provides a sustainable, practical, and proven path to delivering extreme fast charging that will accelerate mass EV adoption. We remain ahead of schedule for our planned milestones as we continue our path to commercialization.

StoreDot recently announced anticipated 2024 milestones including the demonstration of the world’s first EV pack equipped with XFC technology, shipping prismatic B-samples to OEMs, and expanding its operations in the US.

StoreDot remains on track with production-readiness of XFC cells that can deliver 100 miles charged in 5 minutes this year, 100 miles charged in 4 minutes in 2026 and 100 miles charged in 3 minutes by 2028.
