In an unprecedented leap forward for electric vehicle (EV) technology, StoreDot, the leader in silicon-dominant extreme fast charging (XFC) battery innovation, has achieved a world-first milestone. The company announced on April 4th, 2024, from Herzliya, Israel, that it successfully completed over 2,000 consecutive XFC cycles with its silicon-dominant battery cells, maintaining more than 80% of their initial capacity. This development promises EV drivers the ability to quickly recharge their vehicles in just minutes daily, without the usual concerns over battery life degradation.
Demonstrating remarkable energy efficiency, the tested cells showcased an energy density of at least 330Wh/kg and 860Wh/L at the stack level. These cells were repeatedly charged from 10% to 80% capacity within a mere 10 minutes, exhibiting a charge rate of 4.2C, while being discharged at a rate of 1C.
Battery cycle life, an indicator of a battery’s longevity, is determined by the number of charge-discharge cycles a battery can sustain before its capacity falls below 80% of its original state. StoreDot’s breakthrough, with cells enduring 2,000 cycles while still achieving the 80% capacity retention threshold, sets a new industry standard. This performance not only surpasses existing and forthcoming durability regulations for EVs but also provides leeway for addressing other real-world aging factors, thus ensuring longer battery life and greater value for EV owners.
This milestone follows StoreDot’s March 2022 announcement of reaching 1,250 cycles with smaller cells and represents significant progress in scaling and validating its technology. The company has conducted tests with over 15 EV brands, using cells of 30Ah capacity, now surpassing the impressive 2,000 XFC cycle threshold.
Yaron Fein, StoreDot’s Executive Vice President of R&D, stated, “Crossing the 2,000 cycle threshold with our extreme fast charging cells underscores StoreDot’s leadership in EV battery innovation. This achievement affirms the durability and long-term performance of our silicon-dominant XFC batteries as we move closer to commercialization. StoreDot continues to lead the way, achieving our milestones and fulfilling our commitment to offer automakers a dependable, extreme fast charging solution that supports their emission-reduction objectives.”
Looking ahead to 2024, StoreDot has outlined ambitious goals, including unveiling the first EV battery pack equipped with XFC technology, dispatching prismatic B-sample batteries to OEMs, forging strategic manufacturing partnerships, and expanding its operations in the United States as part of its commercialization journey.
StoreDot is on course to achieve production readiness for XFC cells capable of charging 100 miles in just 5 minutes within this year. The company’s roadmap includes reducing this charging time to 4 minutes by 2026 and achieving a groundbreaking 3-minute charge for 100 miles by 2028, marking a significant stride towards the future of electric mobility.
