Are hybrid cars more enviromentally conscious than gas or diesel cars?

I know that the mileage is better but I’ve heard with the manufacturing of the battery it doesn’t turn out to be any better. I haven’t been able to find any concrete statistics or anything though, does anybody know of any websites, or have some information?
Thanks so much!
The battery manufacturing issues are a myth. [...]
