StoreDot Made Engineering Samples For Its 5-Minutes Fast-Charging Cell

• https://insideevs.com,

StoreDot first promised to release a fast-charging cell in 2015. In 2017, it made a demonstration that these batteries did what it said they would. In 2019, when they could be already for sale, StoreDot made another demonstration with a scooter that had 15 percent of charge and allegedly reached full charge in five minutes. Back to 2021, the company now says it will offer engineering samples of its cells.

That would be a harbinger of production, but StoreDot did not mention which companies will get these engineering samples to perform tests. Will they be smartphone, drone, or electric car manufacturers? In the pictures, we can see the pouch cells go from 3V to 4.2V, pretty much the same voltages 18650 or 2170 cells work with – and all technical details we have about them.

StoreDot says its cells use metalloid nanoparticles. An article at The Guardian about it states this metalloid is germanium, a semiconductor that would have helped the company achieve fast-charging without risking dendrite formation. Another advantage of the new batteries would be that it can be produced in current lithium-ion cell factories just with a few changes, something Echion also promised with its "magic" powder.

Although this may seem like good news, StoreDot still needs to tell us in which conditions its batteries can charge in only five minutes. What voltage does it need to get there: 800V, such as the one the Porsche Taycan accepts, or 900V, like that in which the Lucid Air works? How powerful must the fast chargers be: 270 kW, 350 kW, more than that?
