startup to crank out what could be the batteries that reside in our future electric vehicles, but it seems to be edging ever closer to landing a full-blown contract with General Motors. GM has already selected the Massachusetts-based company to "develop batteries that might be used for the Saturn Vue," and it is pondering the idea of awarding the battery maker a similar deal for the Volt. The firm is garnering a good bit of praise for its "long-lasting, safe rechargeable Li-ions" that could potentially power the all-electric / hybrid vehicles of the future, but rather than relying on "cobalt oxide, it used iron phosphate assembled in a novel, nano-structure." Interestingly, the outfit's current offerings started out with the idea of utilizing self-assembling cells, but after they proved "intractably hard to develop," the idea was scraped in favor of the less pricey Li-ion approach. Still, don't expect these guys to run the table on automotive contracts, as there's already quite a few formidable opponents on the loose.
