A new Li-Ion design in principle would allow EVs and other batteries to be charged 80% in ten minutes, but:

1) its early days

2) deployment at scale of a system which heats batteries internally to 60C has to be tested and understood: heat has to dissipate. This is not a "no cost" change, either in the bill of materials, or the physical engineering of battery systems and containment

3) it is however very cool! (ha) I read a lot of EV websites and a hot (ha) topic is how hard it is getting to plug into public chargepoints because the population of EV owners is rising faster than the deployment of charging stations.

Tesla’s new generation of superchargers already promises something similar for Model 3. Interestingly, you need to select supercharger in navigation system so it can condition the battery before arrival to get best charging time.

As I understand it, this change wraps the anodes in a conductive heater so the thermally efficient region is kept small, so it's potentially bad aspects are contained. It can heat up fast so is kind-of preconditioning, but perhaps less onerous.
