Shenzhen lithium battery manufacturers explain the advantages and disadvantages of polymer lithium batteries

Polymer lithium batteries are widely used in all walks of life. Because of their excellent plasticity, they are widely used in electronic equipment in all walks of life. The polymer lithium ion battery is a new type of battery with higher energy density, miniaturization, thinning, light weight, high safety, long cycle life and low cost. In summary, the polymer carp ion battery has the following advantages: 1. Good safety performance. The polymer lithium-ion battery is structured with aluminum-plastic soft packaging, which is different from the metal shell of the liquid battery. Once a safety hazard occurs, the liquid battery is prone to explode, while the polymer battery will only blow up at best. 2. The thickness is small and it can be made thinner. Ordinary liquid lithium-ion batteries use the method of customizing the shell first, and then plugging the positive and negative materials. There is a technical bottleneck when the thickness is less than 3.6 mm. The polymer cell does not have this problem, and the thickness can be less than 1 mm. 3. Light weight. The weight of polymer lithium ion batteries is 40% lighter than steel shell lithium ion batteries of the same capacity and 20% lighter than aluminum shell batteries. 4. Large capacity. The polymer lithium ion battery has a capacity 10%-15% higher than the steel shell battery of the same size and 5%-10% higher than the aluminum shell battery: 5, and the internal resistance is small. The internal resistance of polymer batteries is smaller than that of ordinary liquid batteries, and the internal resistance of domestic polymer batteries can even be less than 35 milliohms, which greatly reduces the self-consumption of the battery. This kind of polymer lithium ion 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. 6. The shape can be customized. Polymer lithium-ion batteries 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 customized according to the needs to make full use of the battery shell space and improve battery capacity. 7. Good discharge characteristics. Polymer lithium ion batteries use gel electrolyte, which has stable discharge characteristics and a higher discharge platform than liquid electrolytes. 8. The design of the protection board is simple. Due to the use of polymer materials, the battery core does not fire or explode, and the battery core itself has sufficient safety. Therefore, the protection circuit design of the polymer lithium-ion battery can be considered to omit the PTC and fuse, thereby saving battery costs.
