Feasible? Sure, you just need a nuclear reactor for every charging point.
Quotethe industrial production of special electrolytes may be costly. It also remains to be seen how the batteries will perform in long-term tests with higher cycle counts.
So...not a breakthrough. Like every other "Hey we developed a new way of charging batteries in a few years, we just have to ramp it up to production, keep costs low, etc. etc..."
Without a scalable production process, it's niche and a preview of absolutely nothing to us measly consumers.
Even the first few Solid State batteries in production offer no advantage over LI-Ion that benefits the consumer.
