Description
Capacity-type NFM-N20 layered oxide is a low-nickel product with high capacity, meaning it does not require extensive use of expensive nickel raw materials during manufacturing while still ensuring a high specific discharge capacity (>140 mAh/g). This material also features low residual alkali (<3000 ppmw), which enhances battery safety performance. Another key advantage of the capacity-type NFM-N20 layered oxide is its long cycle life; after 3000+ cycles (1C/1C, 2.0–4.0V), it maintains over 80% capacity retention. High-voltage NFM-N2-H layered oxide: The company adopts a low-nickel (Ni content ≤20%) design philosophy, utilizing a one-step sintering preparation process combined with "composite doping + nano-coating" technology. The resulting material exhibits excellent rate capability and long cycle performance, achieving reversible capacity at a higher voltage platform of 4.1V.
