What are the advantages of polymer lithium batteries

1. The task voltage of a 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. The capacity density is large, and its capacity density is 1.5 to 2.5 times that of nickel-metal hydride batteries or nickel-cadmium batteries, and perhaps even higher. The self-discharge is small, and its capacity loss is also small after being left for a long time. 2. Long life, the cycle life can reach more than 500 times in normal use, no memory effect, no need to empty the remaining power before charging, easy to use. The safety function 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 can only blow up at best. 3. The thickness is small, and it can be made thinner and ultra-thin, and the battery can be assembled into a credit card. Generally, liquid lithium batteries use the method of customizing the shell first, and then plugging the positive and negative materials. The thickness is below 3.6mm and there is a technical bottleneck. Polymer batteries do not have this problem. The thickness can be below 1mm, which is in line with the current demand for mobile phones. . 4. The light-weight battery using polymer electrolyte does 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. 5. 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. Color screens and MMS are newly released on the market. Most mobile phones also use polymer batteries. 6. Small internal resistance. 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. In time, it can fully meet the 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-metal hydride batteries. 7. The shape can be customized, the manufacturer does not need to be limited to the standard shape, and can be economically made into a suitable size. Polymer batteries can add or increase the thickness of the battery cell according to the needs of customers, and develop new battery cell models, which are inexpensive and have a short mold opening cycle. Some can even be tailored to the shape of the mobile phone to fully use the battery shell space and improve battery capacity. 8. Good discharge characteristics. Polymer batteries use colloidal electrolytes. Compared with liquid electrolytes, colloidal electrolytes have bumpy discharge characteristics and a higher discharge platform. The maintenance board design is complicated. Due to the use of polymer materials, the battery core does not catch fire or explode, and the battery itself has sufficient safety. Therefore, the maintenance circuit design of the polymer battery can be considered to omit the PTC and fuse, thereby saving battery costs.
