Making EV batteries begins in the mining stages. Materials like cobalt, rare earth metals, graphite, lithium, and steel-making products are all some of the components involved in creating EV batteries.
The primary ingredient, lithium, needs to be mined and processed until it is battery grade. Afterwhich it is then with the other materials battery metals are formed into electrodes which are grouped into cells. These cells are then grouped into something called a module, and groupings of modules are called battery packs. In a way, it’s like making a LEGO structure.
