And this is...what...bad?

This is obviously at a prototype stage.

They clearly state that this tech would need further improvements including significantly increased capacity. But that may only be a question of size as is the case with pretty much every other battery technology.

And they produce 3V max--so what? Lead acid cells' nominal voltage is 1.2V, lipo 3.7, Nickel is like 1.3V (I can't recall for sure). Want more voltage, wire cells in series, want more current and capacity, wire in parallel.

The battery tech has interesting, useful properties that offer some promise. I don't really see why you're shitting on it. They're not claiming this is some paradigm changing tech or anything.

Before condescendingly ask if I know anything about electronics or how my phone works, while I am admittedly weak on RF design, I have written drivers for accelerometers, gyros, magnetometers, UARTs, displays, GPS receivers, etc., I've done a little bit of work writing code for cameras, I've worked with ADCs, DACs, I have written code for PIC, AVR, ARM, RISC, etc. microcontrollers in C (also a bit of assembly and c++), and I have designed and sold a variety of circuit boards for hobby use using various microcontrollers, sensors, and other components.

I probably don't know how everything in my phone works but I probably have at least a working knowledge of 80-90% of it. I don't do electronics professionally but I've always enjoyed it. That's why, along with enjoying programming, I got my computer engineering degree back when 80386 and 68020 was the latest, greatest (lol) and why I still do electronics and robotics (the kids call it mechatronics now) as a hobby.

Anyway... I am curious to see if they're able to bring this new chemistry to the market in 5 years as they claim. It may not revolutionize anything but it could offer a nice alternative in a variety of applications.
