StoreDot Achieves 1,100 Cycles With ‘100in4” Battery Cells

Israel-based StoreDot, a company working on Extreme Fast Charging (XFC) battery technology for electric vehicles has achieved progress on the development of its next-phase technology roadmap. It comes after the previous announcement of introduction of cells capable of 100 miles in five minutes this year, and 100 in three minutes by 2028.

According to the company, its ‘100in4’ technology prioritises increased energy density and a myriad of technological enhancements. By taking this system approach, it aims to maximise real-world performance with the available charging infrastructure.

Specifically, StoreDot is targeting at least a 10 per cent 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 optimising multiple aspects of the battery, including chemistry, cell and pack engineering, cooling design, and modifications to internal connections.

For the ‘100in4’ technology, StoreDot claims it 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 utilises a small capacity (3Ah) multi-layer battery cell with internal electrode layers similar to the larger battery cells. It claims to have already proven and scaled up for EV packs, showing the scalability and maturity of the prototype cell.

Dr Doron Myersdorf, CEO, StoreDot said, “By taking a balanced, system-level approach, we are unlocking the full potential of our XFC battery technology to maximise real-world performance. Rather than prioritising charging speed, our plan focuses on technological enhancements across the board – energy density, cell and pack design, chemistry, and cooling optimisation. 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 commercialisation,” he added.
