StoreDot becomes first company to achieve more than 2,000 XFC cycles

Specialist in silicon-dominant extreme fast charging (XFC) battery technology for electric vehicles (EVs), StoreDot, has announced it has become the first company to achieve more than 2,000 consecutive XFC cycles, with the silicon dominant battery cells maintaining over 80 percent of their initial capacity.

This means EV drivers can fast charge their cars in minutes every day, without worrying about the health of their battery.

The results, demonstrating high energy density, are from cells achieving at least 330Wh/kg and 860Wh/L at stack level. The cells were charged consecutively from 10 percent to 80 percent in 10 minutes, demonstrating a charge rate of 4.2C, while discharged at a rate of 1C.

Battery cycle life is measured by the number of charge and discharge cycles a battery can undergo before its capacity drops below an industry standard, 80 percent of the original capacity.

The achievement of battery cells capable of withstanding 2,000 cycles while meeting the 80 percent capacity retention benchmark, is therefore a huge industry milestone, with the results far surpassing current and upcoming EV durability regulations. These results leave margins for other ageing factors in the real world, translating to longevity and extended battery life, offering EV owners with a high market value.

In March 2022, StoreDot announced it had achieved 1250 cycles with smaller cells. Since then, the company has been scaling up and validating its technology while testing it with over 15 EV car brands using EV cell capacity of 30Ah which has now exceeded the outstanding 2000 XFC cycles mark.

“Surpassing 2,000 cycles with our extreme fast charging cells solidifies StoreDot's position at the forefront of battery technology innovation for electric vehicles” said Yaron Fein, StoreDot Executive Vice President R&D. “This milestone achievement validates the exceptional long-term performance and reliability of our silicon-dominant XFC batteries as we rapidly progress toward commercialisation. StoreDot continues to set the pace, consistently meeting our milestones and delivering on the promise of providing car manufacturers with a reliable, proven extreme fast charging solution aligned with their zero-emission goals and timeline.”

StoreDot recently announced its anticipated milestones for 2024. These include demonstrating the world's first EV pack equipped with XFC technology, shipping prismatic B-samples to OEMs, signing strategic manufacturing agreements and expanding operations in the US on the path toward commercialisation.

The company is on track with production-readiness of XFC cells that can deliver 100 miles charged in 5 minutes this year and aims to deliver 100 miles charged in 4 minutes in 2026 and 100 miles charged in 3 minutes by 2028.
