Analysis of the performance advantages of polymer batteries

Functional advantages of polymer batteries 1. Small size and 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 are This problem does not exist, and the thickness can be less than 1mm, which is in line with the current demand for mobile phones. 2. Large capacity; polymer lithium battery has a capacity of 10-15% higher than that of steel shell batteries of the same size and 5-10% higher than aluminum shell batteries. It has become the first choice of customers. At present, fishing devices, electric fishing machines, etc. are currently on the market. Most of them use polymer lithium batteries. 3. Light weight; polymer lithium battery is 40% lighter than steel shell lithium battery with the same capacity and specifications, and 20% lighter than aluminum shell battery. Fourth, the safety function is good; once a safety hazard occurs, the liquid battery will simply explode, while the polymer battery will only blow up at best. Because the polymer lithium battery uses aluminum-plastic soft packaging in structure, it is different from the metal shell of the liquid battery. 5. 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 battery life. The standby time 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 has become the most anticipated product to replace nickel-hydrogen batteries. 6. The shape can be customized; the polymer lithium battery can add or reduce the thickness of the cell according to the needs of customers, and develop new cell types, which are cheap and short in mold opening cycle. Some can even be customized according to the shape of the mobile phone. Make full use of the battery shell space to improve battery capacity. 7. Good discharge characteristics; colloidal electrolyte is used for polymer lithium battery, which has stable discharge characteristics and higher discharge channels than liquid electrolyte. 8. The protection board planning is simple; because the polymer lithium battery uses polymer materials, the battery core does not catch fire and does not explode, and the battery itself has sufficient safety. Therefore, the protection circuit planning of the polymer battery can be considered to omit the PTC and fuse. Then save battery costs.
