It’s been a long-held belief that energy-dense materials (e.g. NMC or LMFP) are essential for high performance EVs. Well, BYD have just shattered that belief.

BYD are releasing a LFP (yes LFP!) supercar, with a 135.5 kWh pack, offering a range of almost 500 miles, and the ability to charge from 30% to 80% in 10 minutes.

Manufacturers within the western supply chain often tout the necessity of LMFP for higher performance and lower cost, but as the graph below shows (thanks to Jeremy Lowen for this modelling), as lithium price falls, the cost advantage of LMFP is eaten away. Furthermore, its increased energy density comes at a cost of lower cycle life, due to manganese dissolution, reducing its advantage over the resilient LFP.

Exawatt has long believed the value of LFP at a system level has been underappreciated in the industry. Is it time for western OEMs to park more of their NMC or LMFP vehicles, with a shift to the tried and trusted LFP chemistry?
