What are the important advantages of polymer lithium batteries, do you know?

The polymer lithium battery not only has high safety, but also has the advantages of being thinner, arbitrarily large, and arbitrarily shaped. The outer shell also uses a lighter aluminum-plastic composite film. However, its low-temperature discharge performance may have room for improvement. The safety performance is good. The polymer lithium battery adopts aluminum-plastic soft packaging in the 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. Small thickness, can be made thinner. Ordinary liquid lithium batteries adopt the method of customizing the shell first, and then plugging the positive and negative electrodes. The thickness is below 3.6mm, and there is a technical bottleneck. The polymer cell does not have this problem, and the thickness can be made. Below 1mm, it is in line with the current demand for mobile phones. Light weight, polymer lithium battery is 40% lighter than steel shell lithium battery of the same capacity and 20% lighter than aluminum shell battery. Large capacity, polymer battery has a capacity of 10-15% higher than steel shell batteries of the same size and 5-10% higher than aluminum shell batteries. It has become the first choice for color screen mobile phones and MMS mobile phones. Nowadays, there are new color screen and MMS mobile phones on the market. Also mostly use polymer batteries. The internal resistance is small, and the internal resistance of polymer batteries is smaller than that of ordinary liquid batteries. At present, the internal resistance of domestic polymer batteries can even be less than 35m, which greatly reduces the self-consumption of the battery and prolongs the standby time of the mobile phone. , Can reach the level of international standards. This kind of polymer lithium battery that supports large discharge current is an ideal choice for remote control models, and it has become the most promising product to replace nickel-hydrogen batteries.
