Do you konw the advantages and disadvantages of ternary lithium battery

Materials that are more balanced in terms of capacity and safety, have better recycling performance than normal lithium cobalt acid. Due to technical reasons, the nominal voltage in the early stages was only 3.5-3 .6 V, which was limited in the range of use. However, until now, with the continuous improvement of the formula and The structure is perfect, The nominal voltage of the battery has reached 3.7 V, and the capacity has reached or exceeded the level of lithium cobalt oxide batteries.

Advantages and disadvantages of three-way lithium batteries

Three lithium battery advantages:

Since the beginning of 2014, the lithium battery of ternary materials has been continuously modified in all aspects and the number of cycles has been increasing. At present, the appropriate increase in costs can reach more than 1,500 times, and the safety performance of lithium batteries of ternary materials has also been continuously improving. Lithium phosphate is getting closer. In the past two years, the newly emerging nickel-cobalt aluminum new ternary material, although it has high environmental requirements during the battery manufacturing process, its stability and safety have been further improved, and it has been recognized and tested by many battery plants.

1, high voltage platform. Voltage platform is an important index of battery energy density, which determines the basic performance and cost of battery. Therefore, it is of great significance to the selection of battery materials. The higher the voltage platform, the larger the capacity, the same size, weight, and even the same time battery, and the higher the voltage platform, the higher the lithium battery range. The voltage platform of the ternary material is obviously 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 vibration density

Advantages and disadvantages of three-way lithium batteries

Disadvantages of ternary lithium batteries:

1, poor security

2, poor temperature resistance

3, poor life

4, high-power discharge difference

5, the elements are toxic(three lithium battery high-power charging and discharging temperature rises sharply, high temperature release oxygen is very easy to burn)
