StoreDot’s extreme fast charging battery cells show no additional degradation when compared to slow charging

StoreDot, a developer of extreme fast charging 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 demonstrates 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.

StoreDot’s commitment to innovation and collaboration is being demonstrated through its rapidly growing global network of strategic partnerships with investors, leading EV OEMs, and manufacturing partners. Global automotive and EV manufacturers such as Daimler, Ola Electric, Polestar, VinFast, and Volvo Cars are already key strategic partners and investors of the company.

Recently StoreDot reported strong performance feedback for the evaluation and integration of A-Samples testing phase of its XFC EV battery cells. The comprehensive testing programs took place earlier this year with 15 leading global automotive brand manufacturers from Europe, Asia, and the US, as well as several of StoreDot’s strategic ecosystem partners, with many of them now moving onto B-Sample and EV integration programs, according to the company.
