What are the advantages of polymer 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-hydrogen and nickel-cadmium batteries. 2. The capacity density is large, the capacity density is 1.5~2.5 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, the cycle life can reach more than 500 times in normal use. 5. There is no memory effect, no need to empty the remaining power before charging, easy 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 best. 7. The thickness is small, and it can be made thinner and ultra-thin, and the battery can be assembled into a credit card. Ordinary liquid lithium batteries use the method of customizing the shell first, and then plugging the positive and negative materials. The thickness of the battery is below 3.6mm, and there is a technical bottleneck. The polymer cell does not have this problem. The thickness can be below 1mm, which is in line with the current mobile phone demand. . 8. Lightweight batteries using polymer electrolytes do not require a metal shell as a protective outer packaging. The weight of a polymer battery is 40% lighter than a steel shell lithium battery of the same capacity and 20% lighter than an aluminum shell battery. 9. Large-capacity polymer batteries have a capacity of 10-15% higher than steel-shell batteries of the same size and 5-10% higher than aluminum-shell batteries. They have become the first choice for color screen mobile phones and MMS mobile phones. Nowadays, there are new color screens and MMSs on the market. Most mobile phones also use polymer batteries.
