StoreDot demonstrates 0-86% charge in ten minutes

The Israeli battery developer StoreDot has published a video of a fast-charging process of its current battery cell technology. This is said to be the version that is to go into series production in 2024.

After StoreDot presented its strategic technology roadmap “100inX” in March and set the goal of delivering battery cells that can recharge energy for 100 miles (160 kilometres) of range in just two minutes within the next ten years, StoreDot now demonstrates the charging of a “100in5” battery cell in a video. This is said to be able to recharge power for 100 miles in five minutes.

The demonstration shows a 300 x 100 mm pouch cell manufactured by partner EVE Energy in China – as will be the case in series production from 2024. In the test, the cell was charged from 0 to 86 percent within ten minutes. At no time did the battery temperature exceed 33 degrees Celsius. The test was conducted in front of an audience at EcoMotion Week 2022 in Israel and streamed live.

The 24 Ah cell demonstrated was charged to 20 Ah. According to the display, the voltage was around 4 volts; according to the presenter, the voltage range is 3 to 4.4 volts. Only at a charge level of 69 percent (after 7:33 minutes) was the current voltage of 135 amps cut off.

“Our intensive development program has already delivered batteries capable of exceeding 1200 consecutive extreme fast cycles and we aim to complete the scaling up of more than 1000 cycles in our EV-size cells by the end of this year,” says Yaron Fein, Vice President for Research & Development. “We remain poised to achieve 100in5 by 2024, whilst remaining firmly on track to deliver our ultimate goal of 100in2 by 2032.”

StoreDot CEO Doron Myersdorf sees the live demonstration as proof of the confidence StoreDot has in its technology. “Away from the stage, our transformative technology continues to undergo testing by leading automotive manufacturers in grueling conditions, ensuring no stone is left unturned in the strategic pursuit of delivering excellence to our customers and consigning EV range anxiety to the history books,” Myersdorf said.

Update 08 September 2022

StoreDot has shipped the first production-ready cell samples of its ‘100in5’ technology to automakers. Demonstrated in May, the battery cells, which StoreDot is developing and plans to put into mass production with EVE Energy starting in 2024, can recharge electricity for 100 miles, or 160 kilometres, in five minutes. The 30-ah pouch cells with a silicon-dominated anode now being supplied to automakers will be subjected to intensive field testing by them.

StoreDot unveiled its ‘100inX’ strategic technology roadmap in March, setting a goal of delivering battery cells that can recharge energy for 100 miles (160 kilometres) of range in just two minutes within the next ten years.

“Shipping the large form factor samples of our advanced ‘100in5’ battery technology to over a dozen of strategic partners and potential OEM customers across the globe is a truly historic moment for StoreDot,” said Amir Tirosh, StoreDot Chief Business Officer, before adding: “I am delighted that we have now commenced intensive, real-world testing with leading OEMs and am confident that our cells will exceed OEM expectations with respect to energy density and extreme fast charging. Current performance shows >900 consecutive extreme fast charging (10% to 80%) in just 10 minutes, with more than 300 Wh/kg. We are on track to exceed our commercialization milestone of 1,000 cycles this year.”

Development is not to stop there, however, as Tirosh lays out the next steps: StoreDot plans to begin mass production of the ‘100in5’ cells next year, before improving the battery technology to a ‘100in3’ level by 2028. Within a decade, the company plans to be able to charge 100 km worth of power in 2 minutes.
