The first samples will be available later this year, with a plan for mass production via conventional lithium-ion battery manufacturing lines in 2024. Eve is one of the top tier suppliers of EV and electricity storage system (ESS) batteries in China. The scope of the new framework agreement includes scale-up activities of StoreDot’s XFC technology, followed by the production of engineering samples targeted at showcasing the technology to EV clients. The framework agreement also covers the intention to set up a joint venture for mass production.
The new deal builds on the existing framework agreement signed by StoreDot and Eve Energy in 2018 to collaborate on a small form factor of StoreDot’s XFC technology. In 2019, this XFC battery was used to demonstrate the world’s first full live charge of a two-wheeled EV in just 5 minutes. In January 2021, another major milestone was reached when StoreDot released the first engineering samples of the small form factor produced at EVE Energy’s facility in China.
“Securing sufficient production capability is one of the biggest challenges facing any introduction of a new battery technology to market” said Dr. Doron Myersdorf, StoreDot’s CEO. “However, from day one Eve Energy has shared our vision that XFC is fundamental to accelerate EV adoption and eventually achieve a full transition to electric mobility. Eve’s expert technical knowledge has been instrumental in helping us to reach a number of important milestones including, most recently, the launch of the small form factor XFC samples produced on standard lithium-ion battery manufacturing lines. Importantly, this removed a major barrier to achieving full commercialization of XFC technology by eliminating the need to invest in costly bespoke manufacturing equipment for mass production. Our silicon-dominant anode battery in large form factor represents the next crucial stage of our journey by bringing the charging speed, cost and range of XFC batteries in-line with the goals of the EV industry. These capabilities will be demonstrated later this year via our EV samples produced with EVE Energy.”
StoreDot’s XFC FlashBattery technology enables charging of EV batteries in minutes, rather than hours, achieved primarily by replacing graphite in the cell’s anode with metalloid nano-particles, such as silicon, to overcome major issues in safety, cycle life and cell swelling during the charging process.
