That looks like innovation!

Meh. Nothing more to me than a random doping of the protective layer by salts in a way to slow the degeneration of the lithium by substituting ions from the salt solution in a way that makes them conductive enough to act as both insulator and conductor so that the protective layer doesn't have so much rebuilding to do after every recharge.

Another way of pointing out to EV users that they are much better off charging to 80%, then using all of the battery up down to maybe 5% charge rather than constant recharging every day in the garage as I bet most do out of fears of getting caught w/o enough charge.

It will take a lot more research to determine the practicality and effectiveness of this and whether it will actually yield enough benefit in practice to be of value without inducing any hidden liabilities.

To put another way, it is a kludge to patch over the inherent limitations of Li-ion batteries thus admitting that the technology is far from perfected yet.

This one has a lot of followers though fails to think outside the box: vending machine pre-charged (modular [italics]) batteries, that can be easily manipulated into and out of the vehicle, once batteries become standardized.
