    Batteries are heavy, even lithium batteries.

    Transferring energy into and out of an EV does result in non-negligible energy loss.

    Having a dedicated, stationary battery is a much more space and resource efficient way to provide a grid buffer. Pb-Acid and Iron-air batteries are much better for the environment than Lithium, and much more stable. They are much heavier, but still lighter than a Lithium battery powered EV.
