Battery Chemistry Comparison
| Chemistry | Energy Density | Cycle Life | Safety | Cost/kWh | Share (2024) | Key Manufacturers | Trend |
|---|---|---|---|---|---|---|---|
LFP Lithium Iron Phosphate | 150–180 Wh/kg | 3,000–8,000+ | Excellent | $60–80 | 60% | CATL, BYD, Gotion, CALB | Dominant and growing; cost and safety advantages outweigh lower density |
NMC 811 Nickel Manganese Cobalt (8:1:1) | 250–300 Wh/kg | 1,500–3,000 | Moderate | $95–120 | 18% | LG, Samsung SDI, SK On | Declining share; still preferred for premium long-range EVs |
NCA Nickel Cobalt Aluminum | 260–310 Wh/kg | 1,500–2,500 | Moderate | $95–115 | 9% | Panasonic, Tesla (4680) | Declining; legacy Tesla chemistry being phased toward LFP and next-gen NMC |
LMO Lithium Manganese Oxide | 140–170 Wh/kg | 1,000–2,000 | Good | $70–90 | 2% | Various (blended with NMC) | Niche; primarily used in LMFP blends to boost LFP energy density |
Solid-State Solid-State Lithium-Metal | 350–500 Wh/kg (target) | 1,000–4,000 (target) | Excellent (no liquid electrolyte) | $150–300 (early) | <0.1% | QuantumScape, Solid Power, Toyota, Samsung SDI | Holy grail; mass production expected 2027–2030 if manufacturing challenges resolved |
Sodium-Ion Sodium-Ion | 120–160 Wh/kg | 2,000–5,000 | Excellent | $40–60 | 1% | CATL, BYD, HiNa Battery | Emerging for low-cost EVs and grid storage; no lithium required |
