As with all news about battery technology, I will believe it when I can go out and buy it. Until then it is vapourware. Does anyone know why battery technology

  It's a combination of different factors. First of all there's a great demand for fast charging, high capacity, long lasting batteries. Especially in Cars but also in just about everything else. Second, the Battery Industry is on an exponential curve in terms of capacity [0]. Lastly, we can make all kinds of "better" batteries in the lab. Faster charging, higher density, longer lasting, ... The Main Issue is that any battery advancement needs to be better in all aspects and you need to build mass manufacturing infrastructure to keep the price down. Thus, we get these massive underestimations of the timeframes. However, Batteries do improve all the time. For example, look at the LG Chem INR21700 M50. Compare it to the best cells that were available before it (adjusting for 18650 form factor) and you'll see a noticeable, albeit incremental upgrade that is mass market available and cheap. Those were likely the fabled 21700 Tesla Cells that Musk was gushing over a few years ago.
