A123Systems was just announced as the chief supplier of battery technology to GM for their plug-in electric projects. The partnership is a pretty big deal, and largely has to do with the much-touted safety of A123's batteries.
But they're alleviating some of those fears. Above is a video of an A123 battery being punctured by a nail followed by a tradtional Li-ion being punctured by a nail. The difference is obvious. Sure, there's some smoking with the A123 cell, but the traditional li-ion very nearly explodes and actually begins to melt before the fire is out.
This, on the whole, is great news for electric cars. Now we just have to wonder how much cost these things will add to traditional NiMH hybrids.
