On page 13 of the report A Lithium Shortage: Are Electric Vehicles Under Threat? we’re shown a comparison on the amount of lithium required for hybrid electric vehicles (HEV), plug-in hybrid electric vehicles (PHEV) and pure electric vehicles (EV). We learn that you need on average 10 units lithium per EV, 5 units per PHEV, and 1 unit per HEV.
I haven’t been able to found any documentation on the amount of graphite required for these same vehicle types but we do have the following quote from Stephen Riddle, CEO of Asbury Carbons, a 118-year-old company described as “the world’s carbon and graphite source”:
I see hybrid vehicles being a big percentage of future car sales, but not the electric vehicles because they’re just too expensive. Unfortunately, the hybrids don’t use anywhere near the amount of graphite in their battery systems that the electric vehicle does.
