What are the general advantages and disadvantages of ternary material lithium batteries?

The advantages of ternary material lithium batteries are materials that are more balanced in terms of capacity and safety, and have better cycle performance than normal lithium cobalt oxide. In the early stage, due to technical reasons, its nominal voltage is only 3.5-3.6V, which is limited in the scope of use. At present, with the continuous improvement of the formula and the perfect structure, the nominal voltage of the ternary lithium battery has reached 3.7V, and the capacity has reached or exceeded the level of the lithium cobalt oxide battery. All aspects of the ternary material lithium battery are constantly being modified, and the number of cycles is constantly increasing. At present, the cost of the appropriate increase can reach more than 1500 times. The safety performance of the ternary material lithium battery is also continuously improving, and more and more iron phosphate Lithium is close. The new nickel-cobalt-aluminum ternary materials that have emerged in the past two years have higher environmental requirements in the battery manufacturing process, but their stability and safety have been further improved, and they have been recognized and trial-produced by many battery manufacturers. 1. High voltage platform. The voltage platform is an important indicator of the energy density of a ternary lithium battery, which determines the basic efficiency and cost of the battery. Therefore, the selection of battery materials is of vital significance. The higher the voltage platform, the greater the specific capacity, and certainly the same size, weight, and even the same ampere-hour battery, the higher the voltage platform of the ternary material lithium battery has a longer range. The voltage platform of the ternary lithium battery material is clearly higher than that of lithium iron phosphate, the high line can reach 4.2 volts, and the discharge platform can reach 3.6 or 3.7 volts. 2. High energy density 3. High tap density. Disadvantages of ternary lithium battery: 1. Poor safety 2. Poor high temperature resistance 3. Poor life span 4. Poor high-power discharge Statement: Some pictures and content of articles published on this site are from the Internet.
