Ni-rich layered oxides, like NCM-811, are promising lithium-ion battery cathode materials for applications such as electric vehicles. However, pronounced capacity fading, especially at high voltages, still lead to a limited cycle life, whereby the underlying degradation mechanisms, e.g. whether they are detrimental reactions in the bulk or at the surface, are still …
The NMC 811 battery is not a unique and novel battery type, but an improvement on what is already on the market. This foundation is composed of the mainstream lithium battery, in accordance with the different dosage ratios of nickel, cobalt and manganese materials of the battery cathode.
Both batteries were simultaneously charged to 4.2V at a 1C rate and discharged to 3.0V at a 5C rate. At the 500th cycle, the capacity retention rate of the NMC 811 battery was 93%, which was higher than that of the LCO battery. Moreover, the dynamic voltage imbalance is less than 100 mV, making the NMC 811 more stable and safer.
The 811 refers to the ratio of metals in the active material that combine to give the high performance: nickel provides high energy density while the manganese and cobalt help to stabilize the spinel crystal structure to extend the cycle lifetime at moderate-high operating temperatures.
The surface coating method will weaken the agglomeration phenomenon of NCM 811 materials. An appropriate coating amount of 1.5% will achieve the best battery performance. After cycles, the increased coated material size is the main reason for performance degradation.
Using the NMC 811 battery actually reduces the weight by 15%, resulting in an additional 30% operating time and lower maintenance costs. The NMC 811 battery from Grepow also has a long life cycle of over 600 cycles, as shown in the test chart comparing the NMC 811 battery to the LCO battery.
Here, it needs to be mentioned that the NMC 811 (2 mAh)||Li x Si (2 mAh) battery is different from the NMC 811 (2 mAh)||Si (1.0 mAh) normal battery with Li plating on the Si anode, where the low CE of Si and Li plating on Si cause rapid capacity decay at a rate much faster than the NMC 811 (2 mAh)||Si (2.0 mAh) battery ( Figures 6 C, 6D, and S7 B).
