NMC, LFP, NCA and LMFP
Why manufacturers pick different cathodes for different cars.
You'll learn
- Explain nmc, lfp, nca and lmfp at engineering level
- Read the numbers that define the behaviour
- Apply the idea to a real pack
Overview
Cathode chemistry sets energy density, cost, cycle life, safety margin and cold-weather behaviour. No chemistry wins on every axis.
In depth
Cathode families at a glance
| NMC | LFP | NCA | LMFP | |
|---|---|---|---|---|
| Cell energy density | 200–260 Wh/kg | 140–190 Wh/kg | 230–280 Wh/kg | 180–210 Wh/kg |
| Cycle life | 1,500–2,500 | 3,000–6,000 | 1,000–2,000 | 2,000–4,000 |
| Cobalt content | Moderate | None | Low | None |
| Thermal stability | Good | Excellent | Fair | Very good |
| Typical use | Long-range cars | Standard-range and commercial | Performance cars | Next-gen mainstream |

Key takeaways
Remember this
- Cathode chemistry is a trade-off, not a ranking.
- LFP trades energy density for life, safety and cost.
- Nickel-rich chemistries deliver range and power but age faster.
