The Status Quo: Which Battery Is Fitted in How Many EVs?

The global electric vehicle market is currently dominated by two primary technologies:

• • NMC / NCA ~60% Market Share  —> Premium, Long-Range, Performance
  • LFP   ~35-40% Market Share -> Standard-Range, Volume models, City EVs
  • Others    <5% Market Share    -> Niche, Prototypes, Early Sodium-ion Series

The Two Market Heavyweights

1. NMC / NCA (Nickel-Manganese-Cobalt / Nickel-Cobalt-Aluminum)

• • Market Relevance: Still number one for mid-size, premium, and long-range models (e.g., many models from VW, Audi, BMW, Porsche, Hyundai/Kia, and Tesla Long-Range variants).
  • Why it’s used: Very high energy density combined with low weight. If you want maximum range in a compact space, NMC is hard to beat.
  • Heat Behavior: NMC cells are more temperature-sensitive. Degradation of the cathode material accelerates above 45–50 °C. Furthermore, the Battery Management System (BMS) intervenes early during summer heat. Driving fast on the highway and plugging directly into a 300 kW charger often triggers thermal throttling, slowing down charging to protect the battery.

2. LFP (Lithium Iron Phosphate)

• • Market Relevance: The decade’s fastest riser. Now powers around 35–40% of new EVs globally (e.g., Tesla Model 3/Y Standard Range, BYD, MG4, Volvo EX30).
  • Why it’s used: Free of expensive nickel and cobalt, making it cheaper to produce, extremely durable, and intrinsically safe.
  • Heat Behavior: LFP cells handle heat much more calmly. Their internal resistance drops slightly at higher temperatures, making summer heat less problematic. The covalent phosphorus-oxygen bond is extremely stable, preventing oxygen release even at high temperatures.
  • The Trade-off: Lower energy density. An LFP battery is heavier and bulkier than an NMC battery of equal capacity.
