StoreDot, an Israeli company specializing in the development of lithium-ion batteries for electric vehicles, said its battery cells XFC EV has proven to be able to withstand repeated charging cycles from 10 to 80% at high speed (the operation took only 10 minutes) to then be unloaded in an hour, without suffering structural damage.
EV cells achieved over 1,000 of these extreme charge cycles consecutively before degrading below 80% of their original capacity threshold. There was no noticeable degradation within the first 600 cycles where the cells were charged rapidly between 10 and 80% numerous times. StoreDot claims to expect further improvements by the end of 2022.
Pressed by the online magazine Electrek on the number of fast charge and discharge cycles that StoreDot aims at, CEO Doron Myersdorf replied:
“We have already achieved our agreed target with most OEMs. This already allows for a 500,000km warranty, assuming each cycle has a range of 500km.”
The “100in5” high-performance EV cells (to which we have dedicated this article) allow drivers to consecutively charge 100 miles of range every five minutes of charging.
In March, the company announced that it had achieved 1,200 cycles for its fast-charging cells and shipped the prototypes in pouch format with a density of 300 Wh / kg to several electric vehicle OEM partners and potential customers. . The spread of cells has a double advantage: on the one hand it allows StoreDot to collect a lot of data in a short time (and also to test the cells under different conditions) on the other hand, it offers customers and partners the opportunity to try the product (and help improve it according to their needs) before buying it.
StoreDot has been making numerous advances in its sector for a year now; in September 2021 it announced that it had produced the first fast-charging 4680 cylindrical cell and two months later became the first to start mass production of XFC cells for electric vehicles.
In December 2021, StoreDot announced a new patented technology that uses a background repair mechanism to allow the battery cells to regenerate while in use.
The company is currently focusing on starting mass production of its “100in5” cells at its Chinese factories together with its manufacturing partner, EVE Energy, and says it is close to starting in 2024.
