As Tesla continues on its commendable journey to surpass Ford, GM, Toyota and everyone else in total sales, it's evidently hoping a tie-up with Panasonic will help it accomplish said goal. The two outfits have just agreed to work together in order to develop next-generation battery packs to be used within electric vehicles, which are based around "Nickel-based Lithium ion chemistry." It sounds as if the two are hoping the collaborative effort will actually be mutually beneficial, though both have been coy about when or where this research will lead to implementable results. Hopefully we'll end up with a Model S that can roll 724 miles on a single charge, but it's not like we'd complain (much) if we only got 722.
