According to a relative who's worked in the industry most of his life, the carbon footprint just from manufacturing and disposing of batteries for electric vehicles is not compensated by the decreased emissions. I think the lifetime is ~5 years shorter than the "carbon neutral time" of using a battery over conventional fuel. Much of the research now is to either reduce the carbon footprint of battery manufacture, or to increase the lifetime of the battery to compensate, but the batteries themselves are apparently worse for the environment than the engines they're replacing.
