StoreDot’s XFC pouch cell was demonstrated at ‘Polestar Day’ in Los Angeles yesterday (November 9, 2023), alongside Swedish company Polestar’s prototype battery module, which integrates the XFC technology. The ‘100-in-5’ battery technology is said to offer 100 miles (160km) of range after a five-minute charge.
As part of an ongoing engineering project, the two companies announced their plan to demonstrate the XFC technology at full scale in a Polestar 5 GT prototype in 2024. Polestar plans to have a line-up of five performance EVs by 2026.
As well as 100-in-5, StoreDot’s XFC solutions include charging from 10 per cent to 80 per cent in 10 minutes.
In a statement, Polestar CEO Thomas Ingenlath said: “StoreDot is making huge strides forward in the development of their extreme fast charging technology, and we are a proud investor and partner in its evolution.
“StoreDot’s pioneering extreme fast charging batteries, combined with our upcoming top-of-the-line electric powertrain, can revolutionise the ownership experience for EV owners with the ability to recharge in minutes.”
Dr Doron Myersdorf, StoreDot CEO, said: “Polestar has been one of our key investors and collaborators as we develop our XFC technology. Next year we’ll show how a full-scale battery module developed by Polestar, with this revolutionary technology, can be charged. Charging anxiety will soon be a thing of the past.”
Instead of current lithium-ion batteries using graphite-based electrodes, StoreDot said they have been developing a silicon-based anode design, which could be used on more affordable lithium-iron-phosphate (LFP) batteries. StoreDot believes its anode design could also improve the energy density of LFP batteries.
Dr. Myersdorf added: "We still have lots of work to do to fully integrate our systems into a production car, but our teams are already fully engaged, and we will be demonstrating those results in the coming months."
