What are the technical ways to improve the specific energy of power ternary lithium batteries?

Is the energy density of ternary lithium batteries high? High energy density is the biggest advantage of ternary lithium batteries, so a battery pack with the same weight has a larger battery capacity, and the car can run farther and faster. The voltage platform is an important indicator of battery energy density, which determines the basic efficiency and cost of the battery. The higher the voltage platform, the larger the specific capacity. Therefore, the battery with the same size, weight, and even the same ampere hour has a higher voltage platform. The material lithium battery lasts longer. Is the energy density of ternary lithium batteries high? Ternary lithium-ion power lithium-ion batteries have already seen the ceiling of energy density. The highest individual energy density of lithium batteries with high nickel materials and carbon silicon anodes should be around 300Wh/kg, plus or minus no more than 20Wh/kg. At present, most of the power lithium-ion batteries carried by pure electric vehicles in my country's new energy vehicle market are ternary lithium battery materials and lithium iron phosphate materials. Although the energy density has been greatly improved compared with lead-acid and nickel-metal hydride batteries, it is still difficult to dispel the anxiety of consumers. Technical approaches to improve the specific energy of power ternary lithium batteries 1. Process advancement, but now the battery process design is relatively mature, and there is not much room for increasing the specific energy of the battery; 2. The improvement of material performance is subject to its own physical and chemical properties, with iron phosphate Lithium and ternary lithium as the positive electrode and carbon material as the negative electrode of the lithium-ion power lithium-ion battery are difficult to make a major breakthrough in energy density; 3. New materials and new systems, that is, the development of new materials with high specific energy and the development of ternary power The new system of lithium battery is an important way to greatly increase the specific energy of power lithium-ion batteries in the future. Fourth, the energy density of lithium battery packs is a system problem. Increasing the energy density of the cells is a direct method, but if the cell layout and circuit planning are done well, the weight of the casing is reduced, and the burden on the battery is reduced, which is also to increase the energy density of the battery An effective means.
