Company believes electric vehicles are the future and it is closer than we think
HERZELIYA, Israel - May 14, 2019: Pure electric vehicles (EVs) run on electricity only. They are propelled by one or more electric motors powered by rechargeable battery packs which include hundreds to thousands of battery cells.
Why we believe that EV's will "rule" in the near future? Because of multiple reasons, among them are: energy efficient, being environmentally friendly, performance benefits and reduced maintenance.
EVs do, however, face significant battery-related challenges: driving range, battery cost, weight and recharging time. While the range, cost and weight have been making significant improvement over the last years, charging time remains a major obstacle to speed up global adoption of EV's.
Fully recharging the battery pack can take several hours. Even at a dedicated super charging station, you can spend 40 min or more.
A new-generation battery that charges fully in 5 minutes, providing a range of 300 miles
StoreDot is developing a new type of electric-car battery consisting of proprietary organic compounds – based on the innovative materials used in its flash battery for mobile devices. The EV flash battery will enable a charging experience which is very similar to fueling a gasoline car.
The EV flash battery enables full charge in 5 minutes, providing up to 300 miles (480 km) of driving distance, depending on the model of your EV. StoreDot fast charging technology shortens the amount of time drivers have to wait in line to charge their cars, thus also reducing the number of required charging posts in a given charging station.
Charges an electric car in 5 minutes
EV flash battery’s remarkably fast charging rate is achieved due to StoreDot’s novel materials and new battery structure. The electric vehicle will have a pack comprising of hundreds of EV flash battery cells that can store enough energy for a full EV range on a 5-minute charge. For a 300-mile car, this translates to 60 miles of travel range on a 1-minute charge.
EV Flash Battery Cost
Although the EV flash battery enables the remarkable feature of 5-minute vehicle charging, this will not increase the price of the electric vehicle. As the manufacturing process uses traditional capital equipment, with mostly standard processing, the EV flash battery cost is aligned with Li-ion industry’s cost reduction curve over the coming years, and will benefit the expected economies of scale of the industry as a whole.
Safe and eco-friendly
EV flash battery architecture is built with a highly stable electrode structure, and contains materials that are far less flammable and more stable at high temperatures than traditional Li-ion technology. Consumer safe, EV flash battery incorporates a multi-layer safety-protection structure. In addition, flash battery is environmentally safer than a Li-ion battery, utilizing organic compounds and a friendlier aquatic based manufacturing process.
Fast-charging batteries for EV
Leveraging on the innovation for a new generation of Li-ion cell design, the electric vehicle has a pack comprising of hundreds of EV flash battery cells that can store enough energy for up to 300 miles (480 km) range on a 5-minute charge. This translates to 60 miles of travel on a 1-minute charge.
StoreDot’s core technology incorporates chemically synthesized organic molecules of non-biological origin. These innovative molecules demonstrate uniquely tunable optical and electrochemical properties, which allow for enhanced performance of energy storage devices.
LiBs (Lithium-ion batteries) power today both portable devices and EVs. While exhibiting relatively slow charging and discharging capabilities, over time, the internal chemical reactions inside the battery reduce their ability to retain energy. Yet, StoreDot has succeeded in maximizing the charge transfer rate, and has enhanced it to heighten the superior characteristics of FlashBattery.
LiBs contain inorganic compounds in the battery’s cathode, typically comprising metal oxides or polyanions which are continuously recharged by the insertion of lithium ions. This process limits ionic conductivity, thereby reducing the power density and shortening the battery’s life expectancy. Moreover, the electrolyte used in LiBs is highly volatile and flammable, posing a severe safety risk to consumers, critical especially in electric cars.
Using a unique multifunction electrode (MFE), StoreDot’s FlashBattery combines two benefits of energy storage solutions, incorporating the high-power rapid-charging rate capability with the high-energy storage ability.
This optimized charging ability is achieved through an innovative electrode structure containing proprietary organic polymers with Metal Oxide compounds of the cathode that trigger the redox reactions. This solution enables ions to flow from a modified anode to a modified cathode at a speed that is much faster than existing technologies. Together with a proprietary separator and electrolyte, this new architecture delivers a high current and low internal resistance, with enhanced energy density and a prolonged battery life.
While some battery manufacturers were able to improve only one of the following properties - either increased capacity, fast-charging or extended battery-life - StoreDot’s novel technology has optimized these three parameters simultaneously.
