The Tesla LFP Model 3 is quite a landmark battery pack for Tesla. Up until now everything has revolved around chasing the energy density of cylindrical cells from 18650 to 21700. The 4680 cylindrical is a move to a larger and lower cost cell. This move to Lithium Iron Phosphate (LFP) is perhaps more significant and triggered by the success of BYD and their
