Let us understand what is polymer battery
Lithium-ion batteries can be divided into two categories: liquid lithium-ion batteries and polymer lithium-ion 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.
The main difference between them lies in the difference in electrolytes. Lithium-ion batteries use liquid electrolytes, while polymer lithium-ion batteries use solid polymer electrolytes instead. Objects can be 'dry' or 'colloid'. At present, most of the polymer gel electrolytes are used. We usually call polymer lithium batteries as polymer batteries and lithium ion batteries as lithium batteries.
The polymer battery has a large capacity density, and its capacity density is 1.5~2.5 times or higher than that of a nickel-metal hydride battery or a nickel-cadmium battery. The thickness is small and can be made thinner. Ordinary liquid lithium batteries use the method of customizing the shell first, and plugging the positive and negative materials after the polymer battery. There is a technical bottleneck for the thickness of the polymer battery below 3.6mm, while the polymer battery does 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 working 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, the polymer battery has a capacity of 10-15% higher than that of a steel shell battery of the same size and 5-10% higher than that of an aluminum shell battery.
The self-discharge of polymer batteries is small, and the capacity loss of polymer batteries is 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 a suitable size. The polymer battery can increase or decrease the thickness of the battery cell according to the needs of customers, and develop new battery cell models, which 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 the space and increase the battery capacity.
Polymer batteries have good discharge characteristics. Polymer batteries use gel electrolytes. Compared with liquid electrolytes, gel electrolytes have stable discharge characteristics and a higher discharge platform.
The design of the polymer battery protection board is simple. 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 charge for several hours to 'activate' before use. The safety performance is good. The polymer lithium ion 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. In addition, under the strict standards of the international industry, the polymer batteries produced by Shenzhen Battery Company have always been favored by consumers at home and abroad!
