>"Xiao-Guang Yang and colleagues, Pennsylvania State University, USA, have found that an asymmetric modulation of temperature prevents lithium build-up even at high charging rates.

If the lithium-ion batteries are heated quickly and briefly to around 60 °C during charging, even at 400 kW of charging power, lithium does not deposit on the surface of the anode.

This allows to fill up enough electricity in ten minutes to travel 320 to 480 km in the car."

This is fascinating, not just from a fast charging perspective (though the discovery is truly awesome in this area!), but also from an electrochemistry perspective as well!

In other words, let's say we have an electrochemical process which moves metal from solution or cathode to the anode (or the reverse)... well, perhaps, if all of the components are quickly pre-heated to a certain temperature, perhaps that no longer happens! Or perhaps you get other reactions!

In other words, perhaps there are other electrochemical processes / reactions possible -- if the constitutent parts (cathode, electrolyte, anode) are pre-heated (or pre-cooled!) to various temperatures...

(Also, it seems logical to assume that pressure, that is, perhaps, high pressures -- might influence electrochemical reaction results as well, as is well known in other areas in chemistry...)
