#3Yet again, the useless milliamp-hours per gram for one component of a cell instead of actual energy per unit mass for a whole cell. What is the Watt-hours per kilogram????

And J/cm³. That's usually the limiting factor for phones, I think.

This might have a little more chances to be real than most such announcements, because this is not really "new battery tech".
They use the same components that are traditionally used in some of the most popular non-rechargeable lithium batteries.
What they claim is that they have found a special electrode construction and some additives that allow such batteries to be rechargeable.
It remains to be seen if they will ever succeed to make these batteries survive enough recharging cycles to be competitive with the existing lithium-ion rechargeable batteries.
The claim for much larger capacity is due to the fact that the normally non-rechargeable batteries have an electrode entirely of lithium, unlike the current rechargeable batteries which store the lithium in the pores of the electrode, so the quantity of lithium is much less than in the non-rechargeable batteries.

That's somewhat promising, as manufacturing is why new consumer batteries are always years behind the tech.

#8For how important it is to modern society, the somewhat stagnating state of battery technology in comparison is baffling. Obviously there is a lot of $ thrown on this problem (securing the constant flow of such hopeful articles in the since the 2000s) but per feeling most of the gains since the Nokia days comes from improving HW/SW efficiency.

#9I'd rather have another gas engine from China now than this shit.

Batteries haven’t stagnated. Costs have come way down, densities have gone up, and recharge times have gotten faster. It’s just been more incremental than revolutionary.
Totally new battery ideas are in development but usually it takes 10-20 years for them to mature and have the potential to compete with existing tech. The hard parts are usually reliability, safety, and most of all manufacturing.
Manufacturing is the hard part for a lot of things. We can make 1nm and even smaller chip nodes today but not in quantity. The yield is really low, so these are prototypes and would be fabulously expensive if you tried to get some made. The “latest” node is the one we can manufacture with sufficient yield to be economical.
