Maybe not better in the long run. You need to overhaul the batteries (replacing dead cells can be done individually) every decade with current technology. You also need to overhaul a combustion engine (cylinder bore/hone, worn parts replaced, warped parts milled flat) every decade-ish, so their sustaining carbon costs are about the same. It's at least a lot closer than most people realize.

A PZEV (very low emission ICE vehicle) is the sweet spot right now in terms of overall environmental impact. It will be a few years before EVs are the clear winner.
