"It’s not a full capacity battery yet either." - So how much capacity is it? Pretty much everyone who has one of those USB charging IR helicopters from Think Geek have seen a battery that 'charges in 30 seconds' but how long would it run the phone?
"The diameter of these sphere is 2.1 nanometer. Very, very tiny. And these can be used, because they have special properties and they are robust, in a semi-conductor device or in a battery or in a display. We are talking about new type of materials that can be introduced into different types of devices.” -- Even though I'm trying hard not to reflexively reject anything based on "crystals" (California New Age mysticism) the statement has issues. 2.1 nanometer sphere? What element? (not carbon (1.1 nanometer for C60)).
"StoreDot’s original focus ... was memory chips ... shifted ... to ... fast-charging smartphone batteries, and cadmium-free displays — with its nano-crystal tech offering a cheaper and non-toxic alternative to cadmium in screens." -- Sounds like an experiment result in search of a product, but nowhere do they point to the original paper or research which kicked off this adventure?
"The big challenge for StoreDot is getting an industry that’s used to building electronics one way to switch to something new and different," -- this statement is always untrue for a 'better' thing. If you can do the same thing 10x better as the existing tech, the manufacturing comes to you, you don't have to do anything to 'get the industry' to change. They are motivated to build the products that are going to sell the most, period.
"”This is a new type of material, with new physics, new chemistry, that is actually coming from nature…" -- not only new physics but also new chemistry? Double Nobel Prize time here folks. That kind of statement makes me look for the evidence to back up that claim. Not provided in the article and again no referenced research.
This is one of those cases where if they had just enough money to build a single product, a full capacity battery that charged in 30 seconds. And they produced one, maybe two lots of a few thousand. Then they wake up people who are really really interested in that. But unless they come through with more information on the new physics and chemistry that makes that possible, I will remain skeptical.
To make their video compelling they need to then start a program on the phone, and show it and a clock before the 'low battery' alert goes off. That will give a sense of how many watt-seconds they can hold in that volume.

According to this chart it really works: https://xkcd.com/678/
I am doing research on quantum dot technology, but most of the information seems to be about the usage in LCD screens and solar panels, does anyone have any good resources or information on their use in batteries?
At the same time I see a huge safety issue: If I drop my phone in the water I don't want it to be able to transmit power that quickly.
Remember that story about a year ago about the high school girl who was going to charge your cell phone in 20 seconds? Same promise, same problem - supercapacitors charge really fast, discharge really fast, and just can't compete with a l-ion battery.
As soon as someone demos one of these batteries that can actually provide 10 watt-hours on a 30-second charge, call me. Until then, yawn.
