What is polymer battery do you know

Lithium batteries can be divided into two categories: liquid lithium batteries and polymer lithium batteries. The positive and negative materials used in the polymer are the same as the liquid lithium ion, and the working principle of the battery is basically the same. Their important difference lies in the difference in electrolytes.Lithium batteries use liquid electrolytes, while polymer lithium batteries are replaced by solid polymer electrolytes. This polymer can be dry or colloidal. Part of the use of polymer gel electrolytes usually we call polymer lithium batteries polymer batteries, and lithium batteries are called lithium batteries. The polymer battery has a large capacity density, which is 1.5 to 2.5 times or higher than that of a nickel-hydrogen battery or a nickel-cadmium battery. The thickness is small and can be made thinner. Generally, liquid lithium batteries adopt the method of first customizing the shell and plugging the positive and negative materials after the polymer battery. There is a technical bottleneck for the thickness of polymer batteries below 3.6mm, while polymer batteries do not exist. One problem, the thickness can be less than 1mm, which is in line with the current demand for ultra-thin mobile phones. The operating voltage of polymer battery cells is as high as 3.6v~3.8v, which is much higher than the 1.2V voltage of nickel-hydrogen and nickel-cadmium batteries. Lightweight, the battery using polymer electrolyte does not need a metal shell as a protective outer packaging. The polymer battery is 40% lighter than a steel shell lithium battery of the same capacity and 20% lighter than an aluminum shell battery. Large capacity, polymer battery is 10-15% higher than steel shell battery of the same size and 5-10% higher than aluminum shell battery. The self-discharge of polymer battery is small, and the capacity loss of polymer battery is also very small after being left for a long time. The shape of the polymer battery can be customized, and the manufacturer is not limited to the standard shape, and can be economically made into an appropriate size. Polymer batteries can add or reduce the thickness of battery cells according to customer needs, and develop new battery cell models. They are cheap and have a short mold-opening cycle. Some can even be tailored to the shape of the mobile phone to make full use of space and increase battery capacity. . The polymer battery has good discharge characteristics. The polymer battery uses a gel electrolyte. Compared with the liquid electrolyte, the gel electrolyte has a stable discharge characteristic and a higher discharge platform. The polymer battery protection board is simple in design. Due to the use of polymer materials, the battery core does not catch fire or explode, and the battery core itself has sufficient safety. Long life, the cycle life of polymer battery can reach more than 500 times in normal use. There is no memory effect, there is no need to empty the remaining power before charging, the polymer battery is convenient to use, and there is no need to continue to charge for several hours before use to activate. 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.
