StoreDot says it has hit a groundbreaking milestone by becoming the world’s first company to achieve more than 2,000 consecutive cycles XFC cycles, with the silicon-dominant battery cells maintaining over 80% of their initial capacity.
These results are from cells achieving at least 330Wh/kg and 860Wh/L at stack level. The cells were reportedly charged consecutively from 10% to 80% in 10 minutes, demonstrating a charge rate of 4.2C, while discharged at a rate of 1C.
Battery cycle life is measured by the number of charge and discharge cycles a battery can undergo before its capacity drops below an industry standard, 80% of the original capacity. Such achievement of battery cells capable of withstanding 2,000 cycles while meeting the 80% capacity retention benchmark, which they say represents a huge industry milestone, with the results far surpassing current and upcoming EV durability regulations. These results leave margins for other aging factors in the real world, translating to longevity and extended battery life, offering EV owners a higher market value.
In March 2022, StoreDot announced it had achieved 1250 cycles with smaller cells. Since then, the company has been scaling up and validating its technology while testing it with over 15 EV car brands using EV cell capacity of 30Ah which has now exceeded the outstanding 2000 XFC cycles mark.
Yaron Fein, StoreDot Executive Vice President R&D:
“Surpassing 2,000 cycles with our extreme fast charging cells solidifies StoreDot’s position at the forefront of battery technology innovation for electric vehicles. This milestone achievement validates the exceptional long-term performance and reliability of our silicon-dominant XFC batteries as we rapidly progress toward commercialization. StoreDot continues to set the pace, consistently meeting our milestones and delivering on the promise of providing car manufacturers with a reliable, proven extreme fast charging solution aligned with their zero-emission goals and timeline.”
StoreDot recently announced its anticipated milestones for 2024. These include demonstrating the world’s first EV pack equipped with XFC technology, shipping prismatic B-samples to OEMs, signing strategic manufacturing agreements and expanding operations in the US on the path toward commercialization.
StoreDot is on track with production-readiness of XFC cells that can deliver 100 miles charged in 5 minutes this year. The company aims to deliver 100 miles charged in 4 minutes in 2026 and 100 miles charged in 3 minutes by 2028.
