I've done SOME

work in this field.
1. Battery manufacture is part of a very large chemical industry supply chain. Earth shaking innovation is slow and steady in this field, and will take a lot of time.
2. Flexible batteries

There is a startup I have done in this field and I will say this; there is many a slip between the cup and the lip.
Will the customer pay more money, for less battery capacity, if it is flexible? Or will he go for solid, non-flexible batteries which are tinier and denser, in a flexible device
3. The combination of the capital intensivity of this field, combined with the customers predilection to pay less for better technology in IT , is at odds. Batteries require a lot of money to sustain. There have been quite a few Solyndras in this field, like A123 systems, and it will continue to be a field which acts old-school, slow innovation, much like a chemical company, rather than an IT company. Ironically, IT is where the end applications lie.
