StoreDot demonstrated the capabilities of its electric car battery at the CUBE Technology Fair in Berlin, claiming to achieve a full charge in only five minutes.
However, it must be noted that the exhibition was not allowed to continue for the full period during the tech show as the company had to pack up. Yet, if the technology holds up, there is obviously a huge potential to revolutionise EV cost, safety, and infrastructure.
The company’s ‘FlashBattery’ is reportedly comprised of organic compounds and built upon a stable electrode structure. Different to traditional Li-ion batteries, StoreDot’s product claims to use materials that are far less flammable, have a much higher combustion temperature, and which are environmentally safer in both production and practice.
StoreDot promises that the technology will enable its battery to be fully charged in five minutes and will allow an EV to drive up to 300 miles on a single charge. Considering that a Tesla Supercharger requires around 75 minutes, the FlashBattery could sweep away the market leader in fast-charging infrastructure by allowing anyone to rapidly charge their EV.
Furthermore, StoreDot has declared that the FlashBattery will not add extra cost to the price of a vehicle, because it can be produced using traditional equipment and without non-standard processing.
So how does the FlashBattery work? Beyond the basics, details are somewhat slimmer. We do know that it is synthesised and is of a non-biological origin. According to the company’s website, instead of using inorganic compounds in the battery’s cathode, the FlashBattery uses organic polymers with metal oxide compounds used to trigger redox reactions. By doing this, ions can flow between a modified anode and cathode at a much faster rate – StoreDot likens it to the function of a supercapacitor.
It also adds that compounds are “tuned to match a variety of applications” suggesting the FlashBattery for your phone will be different to that used in your EV.
Details of the size or energy density of the demonstrator pack have been difficult to track down, although a 2015 Charged EVs article stated that an EV FlashBattery was made up of 7,000 cells and had a capacity of 80kWh.
The company, based in Tel Aviv, was founded in 2011 with the initial intention of developing and commercialising peptide-based technology. However, StoreDot decided to change direction in 2015 by applying its previous work, on quantum dots, to all-organic molecules. Now, the company produces LED displays, and batteries for mobile phones and EVs.
Looking to the future, StoreDot’s CEO, Dr. Doron Myserdorf, said: “Fast Charging is the critical missing link needed to make electric vehicles ubiquitous. The currently available battery technology dictates long charging times which makes the EV form of transportation inadequate for the public at large. We’re exploring options with a few strategic partners in the auto space to help us boost the production process in Asia and reach mass production as soon as possible.”
Considering that the company has reportedly received US$42 million in 2014, including an unconfirmed investment from Samsung, it seems that the technology is certainly making waves. ElecTrans will be monitoring the product’s development closely over the next few years.
