Press Release

StoreDot, the extreme fast charging battery pioneer, develops technology for self-repairing cells allowing longer battery life and better electric vehicle performance

  • StoreDot experts have developed an innovative system that identifies underperforming cells, temporarily takes them out of service to fix them without an EV driver experiencing any vehicle interruption or loss of performance
  • Enhances battery life, performance, and safety, improving the driving experience, and benefits the automotive and battery ecosystem
  • StoreDot is a pioneer and leader of extreme fast charging battery technologies, enabling a 50% reduction in charging times at equivalent cost
  • StoreDot gives automotive manufacturers a clear technology roadmap for seamless and rapid transition to electrification to help create a cleaner world

Herzeliya, Israel, 1st December 2021: StoreDot, the pioneer of extreme fast charging (XFC) battery technology for electric vehicles (EVs), has revealed new patented technology that will allow battery cells to regenerate while they are in use, through a seamless background repair mechanism.

The newly developed system includes a suite of software algorithms with corresponding hardware, furthering StoreDot’s leadership in advancing the entire battery ecosystem. The self-repairing system identifies a cell or string of cells that are underperforming or overheating, temporarily disabling them in order to proactively recondition them back to 100% performance, without the driver experiencing any driving interruption or loss of performance in their electric vehicle. This advancement of a ‘self-healing’ approach to electric vehicles will play a major role in prolonging battery life and driving range, as well as improving safety by preventing overheating or any danger of thermal runaway.  

A recent granted global patent, ‘Recovering defective branches and/or cells of battery packs by deep discharges’, covers the novel method of how this innovation should be implemented in various EV battery pack scenarios, while the vehicle is either charging, resting or driving.

Dr Doron Myersdorf, StoreDot CEO “It’s important for us at StoreDot to encourage the global uptake of electric vehicles, so that we can all live in a cleaner, zero-emissions world. Alongside the development of our leading silicon-dominant XFC cells, StoreDot is committed to broadening its portfolio to advance the entire battery eco-system. This latest patented technology is a unique way of repairing individual cells, or groups or cells, when they are in service is a novel advancement to self-repairing electric vehicles. This approach is truly transformative with huge real-world benefits for electric vehicle owners, improving performance, safety and the longevity of their vehicles. It also plays a crucial role in eradicating range-anxiety, which remains the main barrier to electric vehicle ownership.”

This self-repairing cells system is the latest in a string of StoreDot innovations, designed to benefit the entire battery ecosystem. The company recently had patents granted for technologies that deliver electric vehicles a constant range throughout the life of their vehicles, even as the battery deteriorates. It has also made available, through open-source, hardware, and software advancements of a ‘booster’ technology that allows cells to receive a higher charging current, giving even faster charging times even in limited charging infrastructure scenarios.

These sit alongside StoreDot’s rapid advancement in extreme fast charging lithium-ion batteries for use in the automotive sector. The Company is in advanced talks with leading global car makers and remains firmly on track to deliver volumes of XFC batteries, which provide a 50% reduction in charging time at the same cost, by 2024. The Company demonstrates a clear technology roadmap where it is already working on its next generation XED, extreme energy density solid state cells with planned mass production in 2028.

About StoreDot:

StoreDot is a pioneer and leader of extreme fast charging (XFC) batteries that overcome the critical barrier to mainstream EV adoption – range and charging anxiety. The company has revolutionized the conventional Li-ion battery by designing and synthesizing proprietary organic and inorganic compounds, making it possible to fully charge an EV in just five minutes – the same time it takes to refuel a conventional combustion engine vehicle. StoreDot’s battery technology is optimized for best driver experience with XFC in Li-ion batteries, as well as future technologies for extreme energy-density (XED).StoreDot’s strategic investors include BP, Daimler, Samsung Ventures and TDK.

In 2019, the company achieved a world first by demonstrating the live full charge of a two-wheeled EV in just five minutes.

In 2020, the company demonstrated the scalability of its XFC batteries for other industries, by fully charging a commercial drone in five minutes in another world first. Moving XFC battery technology from the lab to a commercially-viable product for the first time, StoreDot has launched engineering samples of its Si dominant anode EV batteries that are manufactured at scale on traditional Li-ion production lines.
