    Important note near the end of the article - they aren’t saying we should cook batteries really -

    “The team’s hypothesis is that the structural disorder developing inside LIBs may become a “tunable parameter” that, if tweaked using chargers at precise voltages to alter said battery composition, could be used to rejuvenate the batteries in our tech without fires.”

    This is a good old idea that goes back to the days of desulfating lead batteries with powerful shocks of high-amperage current. Might just need a special Healing Charger that applies the right voltage/current to dissolve the bad crystals in lithium-ion systems

      With electric cars you might not even need a special charger so much as a special charging cycle. Its already the norm for cars to tell the charger what voltage and current they want, and its already the norm for cars to carefully control their battery’s temperature during charging.

      That’s not to say you’d necessarily be able to do this with just a software update, but its not too far off from the current paradigm.

        Yeah that’s a good point. Ours uses the same refrigerant system as the AC to cool the battery, and the actual “charger” for the battery is inside the car being controlled by its software etc. The cables that plug in on the outside are technically just power wires, with the charging brains inside the car. That would be amazing if they could update the software to rejuvenate the battery once a year or something.

          it would almost certainly need to be done at a fast charger, not at home unless it could do only a few cells at a time. Remember the golden rule: “Don’t set the house on fire by overloading the wiring”.
