A new EV bat­tery devel­oped by a Chi­nese tech start­up claims to solve one of the biggest chal­lenges for elec­tric vehi­cles: cold weath­er per­for­mance. Typ­i­cal­ly, low tem­per­a­tures reduce the capac­i­ty and effi­cien­cy of lithi­um-ion bat­ter­ies, result­ing in low­er range and slow­er charging.

But the Phoenix cell, cre­at­ed by Greater Bay Tech­nol­o­gy, uses ther­mal man­age­ment and super­con­duct­ing mate­ri­als to heat up quick­ly — from ‑20C to 25C in just 5 min­utes. This allows the bat­tery to charge at nor­mal speeds “in all weath­er con­di­tions”, accord­ing to the company.

The Phoenix cell also boasts a high ener­gy den­si­ty, offer­ing up to 1000 km (621 miles) of range on a sin­gle charge. That’s com­pa­ra­ble to the best EVs cur­rent­ly avail­able. The bat­tery is expect­ed to debut in vehi­cles from Aion, a pop­u­lar Chi­nese EV brand, as ear­ly as next year.

Greater Bay Tech­nol­o­gy says the Phoenix bat­tery can deliv­er fast charg­ing and con­sis­tent range in any cli­mate, from extreme heat to extreme cold. This is a major advan­tage over con­ven­tion­al EV bat­ter­ies, which suf­fer from sig­nif­i­cant range loss in cold weather.

The startup’s chair­man, Huang Xiang­dong, said “Once EVs can be dri­ven and main­tained like gaso­line cars, then there’s a greater chance for mass adop­tion.” The key is to over­come issues like lim­it­ed range and slow charg­ing times — two things the Phoenix cell aims to address.

The Phoenix cell could be a game-chang­er for EVs, enabling long range dri­ving in any sea­son — even in the cold­est regions. The tech­nol­o­gy could make elec­tric vehi­cles more con­ve­nient and prac­ti­cal for the mass market.
