Engineers Have Figured Out How to Recharge an Electric Car in 10 Minutes

A team of engineers at Penn State have successfully demonstrated a fast-charging technique that can give an electric vehicle 200 to 300 miles of range in just 10 minutes while maintaining the safety and longevity of its lithium-ion battery. It appears that degradation can be avoided by heating a battery up to a certain temperature, and then quickly lowering it using a vehicle's cooling system. Up to 2,500 charging cycles are possible, which is equivalent to half a million miles of travel.

Lithium-ion batteries degrade when rapidly charged at ambient temperatures under 50 degrees Fahrenheit because, rather than the lithium ions smoothly being inserted into the carbon anodes, the lithium deposits in spikes on the anode surface. Wang and his team realized that if the batteries could heat up to 140 degrees F for only 10 minutes and then rapidly cool to ambient temperatures, lithium spikes would not form and heat degradation of the battery would also not occur.

Sweet.
It wont be happening at home for some time though, major high current is required!
A lot of infrastructure upgrades are needed before it can be rolled out.
And are there any issues if the battery has to be kept at the higher temp for longer when a 10 minute charge isnt possible?
Are there any complications in high or low ambient temps?

Under ideal conditions I question the 10 minute time to completion because heating up and cooling down of a huge battery will take longer than that and then theres the charge time.
Still enough time for a cuppa and chat.
