NMC955 Cathode materials is not the future trend

Currently, two of the common used lithium-ion chemistries--Nickel Manganese Cobalt (NMC) and Lithium Iron Phosphate (LFP) are dominating the EV battery market. In general, compared to LFP,  NMC would have higher energy density, voltage and versatility, but it would have lower life cycle, stability and higher production cost. According to relevant research, the density of NCM523, 622 and 811 is around 160-200Wh/kg, 230Wh/kg,270Wh/kg respectively. However, the energy density of LFP is around 160-180Wh/kg.


TD consider that the energy density of NMC811 is significantly higher than that of NMC523 and NMC622 positively affecting battery performance, and NMC811 has achieved a balance between safety and energy density;thus it is the choice of the OEM. In addition, although NMC955 has a high energy density, it has a large safety hazard. There is currently no obvious trend of NMC811 shifting by NMC955 in next several years.
