What are the advantages and disadvantages of ternary lithium batteries

The ternary lithium battery has high energy density and better cycle performance than normal lithium sulphate. At present, with the continuous improvement of the formula and the perfect structure, the nominal voltage of the battery has reached 3.7V, and the capacity has reached or exceeded the level of lithium sulphate batteries. Ternary material power lithium batteries mainly include nickel diamond lithium aluminate batteries, nickel diamond lithium manganate batteries, etc. The high-temperature structure is unstable, resulting in poor high-temperature safety, and excessive pH can easily cause the monomer to swell and cause malfunctions. Current conditions The cost is not low. The advantages of ternary lithium batteries are: smaller size, higher capacity density, low temperature resistance, and better cycle performance. They are the mainstream of new energy passenger vehicles. Disadvantages: poor thermal stability, analysis will occur at high temperatures of 250-300°C, and the chemical reaction of ternary lithium materials is particularly strong. Once oxygen molecules are released, the electrolyte will burn rapidly under high temperature applications, and then deflagration will occur. For lithium batteries with ternary cathode materials, there are many types of anode materials for lithium batteries, including lithium cobaltate, lithium manganate, lithium nickelate, ternary materials, and lithium iron phosphate. Ternary materials combine the advantages of lithium cobalt oxide, lithium nickel oxide and lithium manganate materials. They have excellent characteristics such as high capacity, low cost, and good safety. They gradually occupy a certain market share in small lithium batteries and are The power lithium battery category has good development prospects.
