What are the advantages of polymer lithium batteries and ternary lithium batteries?

Advantages of polymer lithium battery 1. The working voltage of single battery is as high as 3.6v~3.8v, which is much higher than the 1.2V voltage of nickel-metal hydride and nickel-cadmium batteries. 2. The capacity density is large, and its capacity density is 1.5 to 2.5 times or higher than that of nickel-hydrogen battery or nickel-cadmium battery. 3. The self-discharge is small, and its capacity loss is also small after being placed for a long time. 4. Long life, its cycle life can reach more than 500 times in normal use. 5. There is no memory effect, it is not necessary to empty the remaining power before charging, which is convenient to use. 6. Good safety performance: The polymer lithium battery adopts aluminum-plastic soft packaging in structure, which is different from the metal shell of the liquid battery. Once a safety hazard occurs, the liquid battery is easy to explode, and the polymer battery will only blow up at most. The advantages of the ternary lithium battery Since the beginning of 2014, all aspects of the ternary material lithium battery have been continuously improved, and the number of cycles has been continuously increased. At present, the appropriate increase in cost can reach more than 1,500 times, and the safety performance of the ternary material lithium battery It is also constantly improving, getting closer and closer to lithium iron phosphate. 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. The ternary lithium battery has a high voltage platform. Voltage platform is an important indicator of battery energy density and determines the basic efficiency and cost of the battery. Therefore, the selection of battery materials is of great 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 material is significantly 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. , High energy density, high tap density.
