StoreDot claims XFC battery cells show no additional degradation compared to slow charging

StoreDot, the leader in extreme fast charging (XFC) battery technology for electric vehicles, has confirmed that its silicon dominant extreme fast charging (XFC) battery cells have successfully passed an extended set of charging profile tests.

The results show that consecutive extreme fast charging conditions did not degrade StoreDot’s cells, even after 1000 consecutive XFC cycles – a result that proves the unique characteristics of StoreDot’s 100in5 technology.

In full cycle charge tests, emulating real-world use case, XFC was applied from 10% to 80% of the charge in 10 minutes, with the remaining charging cycle from 0-10% and 80-100% performed with slower (1C) charging. In parallel, these silicon battery cells were also tested for full slow charging cycles from 0% to 100%, and also achieved a similar cycle life performance.

Despite each cycle applying XFC for most of the charge (i.e., 70%), the cells demonstrated no additional degradation – a result that is on a par with cells that were slow charged from 0-100%, emulating the common use case of levels 1 or 2 charging.

Commenting on the latest results, Dr Doron Myersdorf, StoreDot CEO said: "This remarkable accomplishment underscores our commitment to developing cutting-edge technology that is not only extremely fast but also highly durable. The tests safely delivered the charging speed that consumers demand with the best range, whilst preserving the longevity of the vehicle’s battery cells – a crucial combination in reducing users’ anxiety for achieving widespread adoption of EVs.”

He added, “The significance of testing our silicon-batteries under various use-case conditions demonstrates our battery’s robustness regardless of drivers’ charging habits, recharging frequency, or charger power. StoreDot is proud to spearhead battery technology advancements that accelerate mass EV adoption worldwide by giving drivers a seamless and routine worry -free extreme fast charging experience."

StoreDot says that it remains on target for mass production readiness of ‘100in5’ cells next year delivering at least 100 miles, or 160 km of range in just 5 minutes of charging.

StoreDot, which continues to foster a growing network of strategic global partnerships and investors encompassing the entire battery ecosystem, has received investments from global automotive manufacturers such as Daimler, Ola Electric, Polestar, VinFast, and Volvo Cars.

Last year, StoreDot unveiled its ambitious '100inX' strategic technology roadmap, outlining three generations of StoreDot technologies: Silicon dominant XFC, semi-solid state, and post-lithium architecture. This roadmap reiterates that the anticipated milestones will be delivered over the next decade, with 100 miles / 160 kilometres in 5 minutes targeted for 2024, 100 miles in 3 minutes for 2028, and 100 miles in 2 minutes for 2032. StoreDot states that it is on target for mass production readiness of 100in5 technology by 2024.
