from the link you provided: A GM spokesman declined to comment on the timeline for its next announcements on the Volt, which will include naming a supplier for the vehicle's lithium-ion battery pack, the single most expensive element of the vehicle and the component seen as critical to its success.
Maybe there is a chance to Enerdel also, considering the supply issue, that CEO is all the time pointing out - to supply Think-kind small projects is affordable to any battery-maker, but to quarantee it to GM-like giant - its not that easy, especially to A123, beeing small private company.
I will expect some speculations and accordingly some price jump just before the GM announcement, good chance for traders with iron balls!
I hope so. This stock needs some more speculation and hype, as do all the alt energies these days. Long-term problem is that even for the companies that get selected by GM, terms are likely to be pretty tight as GM itself is neither flush with cash, nor able to charge what it wants for EVs. I also wonder if any "part of the Volt program" is baked into Ener1's price currently (something has to be keeping it valued at over half a billion). If so, an announcement that GM didn't select them could be a big blow. Just don't bet the farm either way, it's way too risky.
