On Thursday, Polestar hosted a major event to unveil various plans for the electric car brand. One of the most notable announcements was the progress made in ultra fast charging battery technology in collaboration with Israeli battery start up company StoreDot. Notably, Polestar plans to showcase a working Polestar 5 prototype featuring StoreDot’s batteries in 2024.
For those not familiar with StoreDot, they have been around for several years and gained attention as early as 2017. However, Polestar only began investing in the company last year, drawn in by the promise of incredible charging capabilities. StoreDot claims that their technology could enable an electric car to achieve a 100 mile range in just 5 minutes. The prototype Polestar battery packs are shown with decals showing the ability to charge from 10% to 80% in just 10 minutes.
The appeal of StoreDot’s batteries:
The appeal of StoreDot’s batteries lies in their use of relatively conventional liquid electrolyte battery technology. This is against many others who use solid state designs. Instead of the graphite based electrodes used in current lithium-ion batteries. StoreDot has been focusing on silicon based electrodes. Additionally, while the Polestar prototype is expected to utilize batteries with nickel manganese cobalt (NMC) chemistry. StoreDot suggests on its own site that their silicon based anode design could be applied to lithium-iron-phosphate (LFP) batteries. These types of batteries are set to appear in vehicles from brands like Ford, Chevy, and Toyota, as they are long lasting and cost effective. However, they are not as energy dense or resilient to ambient temperatures as NMC batteries. StoreDot believes that their anode design could also enhance the energy density of LFP batteries.
It is presumed that this Polestar 5 Prototype will be part of their testing to evaluate the performance of these batteries in real world conditions. Polestar need to determine how to implement them on a production scale. It is difficult to gauge how close the batteries are to production, considering that this is just a prototype. It’s possible there may be significant development work still remaining. However, the appeal of charging times comparable to filling up at a gas station is compelling, and it could serve as a great transitional solution or bridge to solid state battery technology.
Currently we are not aware of any Polestar vehicles in Cambodia. However, we do see with many rival brands bringing EV’s there is strong potential for this brand. However, let us know in the comments if you know of any.
