I'm pretty sure a battery is an energy storage mechanism. And currently the electricity at the charging stations is supplied mostly, if not entirely, by coal and natural gas. Thus the battery powered cars are coal/natural gas cars. You don't even need to get into mining of battery material until the electricity at the charging stations is mostly, if not completely, supplied by renewable energy sources.
