An Israeli startup is now mass-producing car batteries that can deliver 100 miles of charge in just five minutes, overcoming a major setback electric vehicles have.
StoreDot, the company that has has delivered rapid-charge versions of lithium-ion batteries for phones and scooters, has now gorged itself on millions in investment dollars and cranked 1,000 car batteries out of a Chinese assembly line.
This huge innovation replaces the graphite anode which causes problems when trying to force energy into the battery and the lithium ions become congested through this method, before phase-shifting into metal and then shorting the battery. StoreDot replaces the graphite with silicon, which not only circumnavigates this problem but reduces costs since silicon is far cheaper. They also claim their technology is “commercially ready”.
The current crop of 1,000 batteries uses germanium, which is also waterproof, and the silicon ones are expected later in the year.
British Petroleum (BP) invested $20 million into the StoreDot batteries, even though it maintains 18,200 gas stations in the UK. According to StoreDot CEO Doron Myersdorf, “they [BP] understand that 10 years from now, all these stations will be obsolete if they don’t repurpose them for charging—batteries are the new oil.”
Battery charging stations can’t deliver the electricity needed to charge a StoreDot battery fully in five minutes however, five minutes will still fill one with 100 miles, which for most users is plenty. This breakthrough will help electric vehicles overpower petrol and diesel cars.
