What is 811 lithium battery?

80% nickel + 10% diamond + 10% manganese, this is the ratio of the positive electrode material of the ternary power lithium ion battery under the high nickel low diamond structure. NCM811 is a ternary lithium battery with nickel and manganese in the cathode material, and the content ratio is 80%:10%:10%. Simply put, it is based on the previous ternary lithium battery to change the electrode material into It was 8:1:1. According to the different consumption ratios of nickel, cobalt and manganese, nickel cobalt manganese ternary lithium batteries can be subdivided into 111 type, 523 type, 622 type and 811 type, etc. At present, 523 and 622 types are the main ones. The single energy The density is 200Wh/kg. The 811 battery can reach 300Wh/kg, which is a 50% increase in energy density compared to the 622 type. This is equivalent to a battery compartment of the same size, which can carry more lithium batteries and greatly reduce the quality of lithium batteries. 811 lithium battery This type of power lithium-ion battery has the characteristics of high energy density and can reduce manufacturing costs. It is logical that high-nickel low-diamond ternary power lithium-ion batteries are loved by new energy vehicle manufacturers. The latest news shows that the commercialization of my country's 811 power lithium-ion battery is steadily advancing, and it will be one of the more feasible research directions for high-quality power lithium-ion battery research in a short period of time. Cost reduction, as far as terminal OEM customers are concerned, NCM811 is the lowest cost per KWh battery. In addition, nickel resources are widely distributed and the price is stable, which is in line with the direction of large-scale industrialization in the future; 2) At present, the industrialization of NCM622 in my country is relatively mature, and it is widely used to support downstream new energy vehicles. NCM811 has started its industrialization prelude and is gradually applied to new models. The technical threshold of high nickel ternary materials is relatively high, and the requirements in terms of preparation technology, equipment and processing environment are clearly higher than those of conventional ternary materials. Large-scale mass production is also difficult. At present, only Rongbai Technology and Dangsheng A few manufacturers such as Technology and Shanshan Energy can realize the mass production of NCMS11. In addition, based on safety considerations, the certification and detection procedures for high-nickel material products by car companies or power lithium-ion battery companies are more complicated and take longer, which will also directly lead to the establishment of first-mover advantages for advantage companies.
