Also, that article about China making as many batteries as the world needs is deceiving if we’re talking about grid scale capacity as opposed to house scale or vehicle batteries. If the world went 100% into renewable energy with grid-scale battery deployment to provide extra capacity to make up for renewable generation variation, there’s no way China could keep up. That’s a LOT of batteries and ongoing replacement as they age and fail.
