NCA cathode powder (lithium nickel cobalt aluminium oxide), grade S. High-nickel layered oxide where aluminium replaces manganese as the stabilising element. Aluminium doping suppresses phase transitions during cycling, which gives NCA better cycle life than NCM811 at comparable nickel content and capacity.

Appearance Grey-black powder
Discharge capacity 190–210 mAh/g at 0.1C
Average voltage 3.7 V vs Li/Li⁺
Voltage window 3.0–4.3 V typical
Stabiliser Aluminium — suppresses phase transition on cycling

Cathode chemistry comparison

Cathode Capacity Avg. voltage Thermal stability Cycle life Cobalt Best for
LFP (LiFePO₄) 150–160 mAh/g 3.2 V Excellent Excellent None Storage, long life, safety
NCM523 155–165 mAh/g 3.7 V Good Good Moderate Balanced cost and performance
NCM622 175–185 mAh/g 3.7 V Moderate Good Lower High energy, workable stability
NCM811 195–210 mAh/g 3.7 V Lower Moderate Low Maximum energy density
NCA 190–210 mAh/g 3.7 V Lower Good Low High energy and high power

NCM is also written NMC; both refer to lithium nickel cobalt manganese oxide. Rising nickel content raises capacity and cuts cobalt cost, but reduces thermal stability and increases moisture sensitivity — that trade-off is the whole story of cathode selection.

NCA vs NCM811

Both sit at roughly 80% nickel and deliver similar capacity. NCA uses aluminium rather than manganese to stabilise the layered structure, which improves cycling stability and power capability but makes the material more sensitive to moisture and harder to process. NCA has historically dominated cylindrical automotive cells, NCM811 the pouch and prismatic formats. If you need power density and cycle life, NCA; if you need easier slurry handling and wider supply, NCM811.

Applications

  • High-power cylindrical cell development
  • Automotive and aerospace cell research
  • Power density and pulse discharge studies
  • Surface coating and dopant research
  • Benchmarking against NCM811 and NCM622

Handling nickel-rich cathodes

Nickel-rich powders are hygroscopic and alkaline. Moisture pickup forms surface LiOH and Li₂CO₃, which raises pH, gels PVDF slurries and generates gas in the finished cell. Store sealed, weigh out quickly, and handle in dry air or a glovebox where possible. Never leave an open container on the bench overnight.
