I don't think so. The added impact of battery manufacturing is quite small compared to the impact of manufacturing any vehicle, and that in turn is a fairly small proportion of the total impact of a vehicle over its lifetime. Only looking at driving, a Prius emits about 238 grams of CO2 per mile. A reasonably efficient EV charging from the US's current generation mix emits about 150 grams/mile. If we assume they'll last 200,000 miles on average, that's about 17 tonnes more CO2 for the Prius. The EV produces in the neighborhood of 6 tonnes more CO2 during manufacture compared to a traditional gas car, and this advantage will be slightly smaller compared to a hybrid.
