While LFP batteries are less dense than NCM (Nickel Cobalt Manganese), they are also considerably cheaper, and they don’t need an expensive conflict metal (cobalt), or the less expensive but still pricey nickel (much of which comes from Russia). By getting rid of the modules, BYD in their “blade” design has made the density of LFP batteries somewhat competitive with NCM, which would work especially well in a really efficient car ie Aptera.
I examined two potential lfp options (CyclenPo 180 wh/kg and Goshen High tech bleeding edge 210 wh/kg). Using current off the shelf CyclenPo lfp increases the pack for the 400 mile pack from about 450lb to 600lb and may save thousands on each vehicle. Switching to lfp definitely should make sense given the shell was designed to store enough batteries for the 1000 mile version.
