Rejuvenating EV Batteries?

[hmp10]

No idea whether this is another of those battery "breakthroughs" that never make it to market, but this does seem interesting:

Chinese scientists develop ‘injection’ to make lithium-ion batteries last longer

Repair technology could significantly extend the lifespan of lithium-ion batteries found in electric vehicles and smartphones.

Interesting article. I wonder if the injection has the potential to restore the battery to its original total capacity??

Well, if this is close to true, you would should see almost immediate and widespread implementation of this technology/technique. Color me skeptical Hmp10

Even if it has legs, immediate implementation is not to be expected. A lot of practical issues would have to be overcome. For instance, you would have to access each battery cell for this injection, so it takes most existing battery module designs off the table. And before carmakers would re-engineer battery packs, this method would have to prove long-term efficacy. It also might only be practical with large pouch cells, as injecting this chemical during a cell's service life into the thousands of cylindrical cells used in a car such as a Lucid would be quite a trick. And the cells themselves would have to be engineered to accept the injections.

Even if it is a viable technology for extending EV battery life, we're a long way from seeing it in any cars.
