StoreDot, the pioneer of extreme fast-charging (XFC) battery technology for electric vehicles, has demonstrated the prototype 4680 form factor that is fully charged in just 10 minutes.
Unveiling its ground-breaking silicon-dominant technology applied in XFC cylindrical cells, the company said that its cylindrical cells utilise a 4680 format, the one increasingly favoured by global carmakers.
In development for over three years, these breakthrough technologies were kicked off at Warwick University in the UK, collaborating with StoreDot's strategic partner – BP. It has been further developed, harnessing experts from across the globe.
With this technology, the global automotive manufacturers will use StoreDot's XFC batteries, which deliver a 50% reduction in charging time at the exact cost in pouch and cylindrical cell forms. Both formats are undergoing a scale-up process at EVE Energy and will be ready for mass production in 2024.
In addition, with such format versatility, the entire industry will be able to leverage StoreDot's newly introduced patent-pending Boost Charging Technology (BOOCT) application.
StoreDot is in discussions with leading automotive manufacturers. It now can offer the automotive industry a clear technology roadmap using silicon-dominant XFC technology and then onto future generation extreme energy-density (XED), based on solid-state technologies that are on target to enter mass production 2028.
According to the company, the work is covered with five patents in cell design and uses its continuous tab technology. Such cell design increases throughput and addresses safety and performance issues typically associated with the hard case structure of cylindrical cells. Testing at the StoreDot facility has shown promising low levels of internal resistance, the company said. Cylindrical cell samples are now ramping up the production lines at EVE Energy, StoreDot's manufacturing partner in China.
