A bit of inaccuracy in the article:
> a typical Li-ion battery retains only 80 percent of its charge capacity after 300 to 500 cycles
That's off by 10x at least. Typical LFP batteries that are widely used now have thousands of cycles. Over 5K in some cases. Some of the solid state batteries that are coming to production in the next few years might do better. 300 to 500 is more typical of some older chemistries. Even NMC batteries used in e.g. Teslas have cycle life spans of at least 1500 or so cycles.
And for reference, if you charge and full de-charge your car that would be 1 cycle. A decade is only 3653 or so cycles (there might be 2 or 3 leap years). Most car vehicle owners don't charge nearly as often or so completely. A typical Tesla that is partially charged maybe once a week or so is not going to need a battery replacement until the 2040s or so.
Anyway, the article carefully avoids talking about energy density. Which is of course the key thing here. Together with other things like charging speeds. Operational temperatures, etc. These all matter.
This is a university study, not a plan to get this to production. Promising and interesting but probably well over a decade away from any serious applications. By that time we might have all sorts of other battery tech that is sitting a bit higher on the technological readiness scale on the market.
