It appears Neah and Shorai are already producing a joint project:
"We are extremely pleased to announce that we have been doing research and development on a lithium battery technology that appears to be far superior to any incumbent technologies (the PowerChip® Battery). At an appropriate time in the near future, once the Company has achieved the next round of performance targets, we will be sharing details with our shareholders. Once completed, we believe our Porous Silicon Battery will be a disruptive power storage system for a whole range of applications from consumer goods to automotive applications, as well as for scalable storage solutions for off-peak and back-up power usage."
I wonder if such a technology would interest Elon Musk, being he is a bit anti-fuel cell at the moment.
From what I can tell, the merger is for the most part complete...only minor details remain...IMO.
