It very much depends. There are many different ways of mining lithium. An Australian hard rock mine will use the same amount of fossil fuel as any other hard rock mine. Brine operations don't use much but the lithium still has to be transported from a desert. Future technology such as DLE (Direct Lithium Extraction) have to potential to require basically no fossil fuels at all.
