The lithium mines I have seen depicted are massive open pit mines, not possible for child labor. You are probably confusing the lithium with the cobalt that is also essential to the battery composition, which is often mined in piecemeal fashion with children. But the lithium extraction is hugely energy dependent, mostly from hydrocarbon fuels.
