So relatively easy to add into batteries.

Easy? You reckon. We have a claim from a respectable source that they've demonstrated something in the lab. What happens before that is "easily added into batteries"? The short list below is a fraction of the tasks needed, only vaguely in order:

* Labs need to verify that there are no new failure modes or performance changes to the battery - eg energy storage at the expense of service life may not be a good trade-off in these days of sealed devices.

* The IP holders need to establish heads of agreement with a battery and/or phone maker as to who will do what, and how rewards will be shared

* Battery makers need to establish that the lab process could be undertaken in a battery plant - if the preparation is too onerous, then it simply may not be possible to make them other than in a lab.

* The battery makers have to work out if it is actually economic to volume manufacture with the additional materials, and additional processing - many good ideas don't make it to the shop simply because nobody will pay the right price.

* Battery makers have to try and source materials of the required quality and quantity (at a low price). If supply chains are constrained now or in future, that feeds back into the economics.

* Battery and phone makers need to establish what price the market will pay - it may be economic at a basic level, but if the market won't pay more, why go to all the effort?

* Battery makers and phone makers need to do tests that will convince their respective insurers that the technology is safe over several years - after the Note 7, they won't be in a hurry to take chances on a much higher energy density battery.

And at every stage there's regulatory compliance, H&S, disposal and recycling. You've got new concerns that if there's three times the energy density, then the consequences of a "not at fault" failure may be far more serious than current technology - if a perforated battery gives off far more noxious fumes or explodes like a small hand grenade, will airlines permit the devices to fly? If you have much higher energy stored, does the new chemistry work and remain effective with fast chargers?
