产品名称：ossila镍锰酸锂

NMC811 (CAS number 179802-95-0) is considered one of the most promising future cathode materials for lithium-ion batteries in electric vehicles due to its high specific energy density, favorable rate capability, and relatively low product cost. It delivers a high specific capacity of ~200 mAh g-1 with a moderately high average discharge potential of ~3.8 V vs Li/Li, a substantial increase of ~25% in energy density compared to that of LiCoO+2.

By adopting the well-known α−NaFeO2 type layered oxide (R3m) structure, it is characterized by a close-packed oxygen lattice and alternating layers of lithium and transition metal ions which reside at the center in octahedral coordination environments.

Electrochemical fluorination enhances the cycling stability of the electrode without altering bulk structure and morphology. ECF-NMC811 cathodes delivered 203.0 mA h g-1 first discharge capacity at the current rate of C/10, with ~98% capacity retention up to 100 cycles.
