Polestar successfully tested a 77 kWh battery using silicon-dominant XFC cells from StoreDot, achieving ultra-fast charging speeds. The goal is to equip the production Polestar 5 with a 100 kWh pack for improved energy efficiency.
Utilizing XFC cells, Polestar aims to reduce charge times, enabling drivers to spend less time at charging stations during long journeys. The technology targets quicker stops similar to conventional petrol refueling experiences.
Polestar's innovative XFC cells offer energy density comparable to NMC batteries. These cells not only enhance charging efficiency but also serve a structural purpose in the battery pack, optimizing cooling performance without adding extra weight.
