Compare different lithium-ion battery chemistries used in EVs (NMC, LFP, NCA).

NMC (Nickel-Manganese-Cobalt) offers high energy density (250+ Wh/kg), good power capability, but uses expensive cobalt. NCA (Nickel-Cobalt-Aluminum) provides highest energy density (300+ Wh/kg) used by Tesla, but with thermal stability concerns. LFP (Lithium Iron Phosphate) offers longest cycle life, best thermal stability, lowest cost, but lower energy density (160-180 Wh/kg). Choice depends on range requirements, cost targets, safety priorities, and intended use. Trend is toward high-nickel NMC for premium vehicles, LFP for standard range and commercial vehicles.
