#12First law of battery tech headlines: it’s all vaporware unless it’s shipping in laptops.

#13Actual paper [1].
They don't have a battery yet. Just a "half-cell".[2] They have the cathode side, but not the anode side, apparently.
This group has access to all the good toys. They're doing X-ray crystallography with a synchrotron beam line. They have a scanning tunneling microscope with a 3-axis nano-manipulator.

#14I always found it confusing that the lithium solution is most of the mass of the battery but all of the energy is in the anode and cathode.

#15I'm thinking the battery explosions will be more spectacular too.
Consider the energy density of a cup of water when viewed as fuel for fusion reactions.

#17> By adding cobalt and oxygen atoms to iron fluoride nanorods
Could someone who knows this area comment whether this sounds expensive to manufacture?

#18It's was about time we moved on to the next energy-storage technology for mobile devices. I can't believe in 2018, battery is still the main issue of all flagships.

Won't it always be an issue? I have a feeling they'll just put in more and better power-hungry hardware and software and we'll be back in the minimally acceptable battery life range.

Right. And if they don’t do that, then the phone will just get thinner. We already have incredible energy density compared to a decade ago, but that budget is used up by shaving millimeters off the thickness.
