StoreDot: ‘five-minute charging becoming commercial reality’
Israeli battery developer StoreDot has made its first – in China produced – ultra fast-charging batteries samples available to showcase to possible manufacturers in the electronics or EV sector. StoreDot showed in 2019 already an electric scooter with its experimental technology charging fully in only five minutes.
Based in Herzeliya, Israel, the company claims that the technology is now ripe to become a commercial reality, also for EVs. The latter would be able to charge in five minutes for a range of 300 km if the appropriate fast-charger infrastructure is available.
StoreDot says it uses “ground-breaking battery technologies based on the design and synthesis of both organic and inorganic compounds”. In fact, they are lithium-ion batteries in which other materials – a thin layer of metalloid nanoparticles – are used for the anode than classic graphite.
Ions can flow at a much higher rate, without the anode to ‘metalize’, which may damage a classic battery. With the nanoparticles, StoreDot uses tin, germanium, and silicon in combination with organic compounds to form the cell chemistry basis.
It all comes to convenience, the people at StoreDot say. People don’t want to wait for hours to have their batteries charged, whether in electronic appliances or electric cars. The company demonstrated the fast-charging first in a smartphone, later in an electric scooter of Spanish manufacturer Torrot. The next step will be to demonstrate it in an electric car.
“We believe fast-charging is crucial for rolling out electrification and as such to making a big difference on the carbon intensity of transport,” says Jon Salkeld, Technology Director of BP Advanced Technologies, in a demo video.
BP invested 20 million dollars in the company, as it is also active in the EV charging business through its ChargeMaster daughter in the UK, managing over 10 000 fast-charging points. The British oil company is only one of many investors, including Daimler, and Samsung.
