Fast EV battery charging: 160km range in 2 minutes in a decade
Israeli fast battery charging developer StoreDot is targeting 160km of range per 5 minutes in 2024 and 2 minutes within a decade.
StoreDot is developing a range of technologies, reporting itself also to be on track for its first milestone – the production of its silicon-dominant anode extreme fast charging (XFC) lithium-ion cells at scale by 2024 that will be capable of delivering 160km of range in 5 minutes of charge.
In parallel, the company says it is at the advanced stages of developing semi-solid state technologies which will further improve the batteries by 40% over 4 years – delivering 160km of charge time in just 3 minutes and be mass production ready by 2028.
This will be followed by full solid-state technologies with an additional 33% improvement to deliver the 2 minute charge target range by 2032.

EV battery swapping – is it set for revival?
Describing the latter as the ultimate goal and “absolutely within our grasp”, Dr Doron Myersdorf, StoreDot CEO, says: “After intense development of our silicon-dominant chemistries we will be mass-production ready by 2024, delivering a transformative product that will overcome the major barrier to the widespread adoption of electric vehicles – charging times and range anxiety.”
He adds that the technology roadmap extends long after 2024, “where each milestone represents an impressive performance improvement – a major impact on the driver’s experience.”
StoreDot’s battery chemistry, in essence, replaces the traditional Li-ion graphite anode with nano-sized silicon particles synthesised together with proprietary small-molecule organic compounds.
This results in a highly potent active material that withstands silicon changes, such as volume expansion during battery charging, issues of energy fade, preeminent rate capability limitations and enhanced safety, the company website states.
“The secret sauce is in our integration of molecular composition and nano-particles, carefully assembled into an optimised XFC battery cell, achieved over a decade-long R&D process applying rigorous machine learning and AI-based data science.”
StoreDot’s XFC cells will be available in both pouch and 4680 family form factors, the formats increasingly favoured by the majority of global car manufacturers.
The pioneering work on the cells has been undertaken with the participation of global experts from Israel, UK, US and in China.
The ‘100in5’ cells are already undergoing real world testing by a number of automotive electric vehicle manufacturers.
