One challenge that climate policy folks are working on is developing the supply chain to make batteries in the U.S. There has been an epic battle over the past 20 years between two types of lithium-ion batteries: nickel manganese cobalt (NMC) and lithium iron phosphate (LFP). While NMC still boasts better energy density, LFP is making a major comeback thanks to its safer, more accessible materials and improving performance. However, China still dominates the LFP supply chain. In this episode, CEO Vivas Kumar of startup Mitra Chem weighs in on why America needs domestic production of LFP materials.
