This is a lab result that has some promise, nothing more. Only a teeny tiny percentage of promising lab results turn into commercially viable products, there are many obstacles along the way from here to there. One of the biggest is that Li batteries have gone through several order of magnitude scalings. That means that any technology that wants to compete with it can't be as good, it must be much better.

It just never does. Just as in the parallel universe with personal airplanes powered by sodium batteries, Lithium-ion and four-wheeled cars never made it to the mainstream. Incumbent power.

There's a universe of uses for batteries. Really depends on what you want it for.

For the average person using consumer products they are usually concerned with energy density and cost. Apart from electric cars most companies don't really care about no. of cycles, especially for phones.

... but don't we charge our phones every day? 1000 cycles feels like a minimum for that - would be required for a phone to last 3 years.

In my experience phone batteries start to deteriorate after about two year.

Mobile phones are the poster child of planned obsolescence as insinuated in my comment.

Surely grid applications doing daily balancing care about cycles.

"For the average person using consumer products..."

That’s a different sentence from “most companies don't really care about no. of cycles”
