Sony must be smelling dolla dolla bills in the EV-charged streets because the company just announced its intentions to fab lithium-ion batteries for the cars mid-decade. The statement, made from its plant in Motomiya, hinges on a future market flush with consumer demand for the earth-friendly autos, and could see the construction of several dedicated factories. Given the Japanese company's recent history eating bits of competitor dust (hello Wii and iPod), we understand its forward-facing desire to become king of this Li-ion hill. But the mega-electronics maker isn't placing all of its batteries in one fuel-source just yet -- it's "also [considering] developing batteries for gasoline-electric vehicles and plug-in hybrids" -- should they win the green energy popularity contest. While we applaud the company for encouraging adoption of the environmentally-friendlier tech, we'd much rather see them make batteries for this bad boy from tomorrowland.
