What are the performance advantages of polymer lithium batteries

1. Good safety performance; once a potential safety hazard occurs, liquid batteries are prone to explode, while polymer batteries are more likely to swell. Because the polymer lithium battery uses aluminum-plastic soft packaging in structure, it is different from the metal shell of the liquid battery. 2. It is small in size and can be made thinner. Generally, 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. Polymer batteries do not have this problem. , The thickness can be less than 1mm, which is in line with the current demand for mobile phones. 3. Large capacity; polymer lithium battery has 10-15% higher capacity than steel shell batteries of the same size and 5-10% higher than aluminum shell batteries. It has become the first choice of consumers. At present, fishing devices and electric fishing machines are on the market. Most of them use polymer lithium batteries. Fourth, the internal resistance is small; 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 mobile phone’s power consumption. The standby time 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 a promising product to replace nickel-metal hydride batteries. Customized production of lithium batteries 5. Light weight; polymer lithium batteries are 40% lighter than steel shell lithium batteries with the same capacity and specifications, and 20% lighter than aluminum shell batteries. Sixth, the discharge characteristics are good; the polymer lithium battery uses a colloidal electrolyte, which has a stable discharge characteristic and a higher discharge platform than a liquid electrolyte. 7. The design of the protection board is simple; because the polymer lithium battery uses polymer materials, the battery core does not catch fire or explode, and the battery itself has sufficient safety. Therefore, the protection circuit design of the polymer battery can consider omitting the PTC and fuse, so Save battery costs. 8. The shape can be customized; the polymer lithium battery can add or reduce the thickness of the battery cell according to the needs of customers, and develop new battery cell models. The price is cheap, the mold opening cycle is short, and some can even be customized according to the shape of the mobile phone. Make full use of the battery shell space to increase battery capacity.
