Detalhes

This product is designed for advanced lithium-ion battery applications requiring high energy density cathodes. The lithium-rich manganese-based composition, with a balanced Ni, Co, and Mn content (approximately 8.4 wt% Ni, 8.5 wt% Co, and 29.4 wt% Mn), delivers an initial discharge capacity of 296.6 mAh/g and a first-cycle efficiency of 89.7% under 0.1 C testing between 4.6–2.0 V. The material exhibits a D50 particle size of 12.55 µm, a BET surface area of 3.64 m²/g, and a tap density of 2.10 g/cm³, supporting good processability and electrode packing. Typical applications include high-voltage cathodes for next-generation electric vehicle batteries and high-capacity energy storage systems where stable cycling and elevated specific capacity are critical.
