Introduction to the advantages of lithium-ion polymer batteries

Polymer lithium-ion batteries are structured with aluminum-plastic soft packaging, which is different from the metal shell of liquid batteries. Once a safety hazard occurs, the liquid batteries are prone to explode, while the polymer batteries can at most only blow up. 2. The thickness is small and can be made thinner. Ordinary liquid lithium ion batteries adopt the method of customizing the shell first, and then plugging the positive and negative electrodes. The thickness is below 3.6mm, there is a technical bottleneck, and 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. Lightweight polymer battery is 40% lighter than steel shell lithium ion battery of the same capacity and 20% lighter than aluminum shell battery. 4. Large-capacity polymer batteries have a capacity of 10-15% higher than steel shell batteries of the same size and 5-10% higher than aluminum shell batteries. They have become the first choice for color screen mobile phones and MMS mobile phones. Nowadays, there are new color screens and MMS on the market. Most mobile phones also use polymer batteries. 5. Small internal resistance. 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 standby time of the mobile phone. In time, it can fully meet the international standards. 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 of the polymer battery can be customized. The thickness of the battery cell can be added or reduced according to the needs of customers, and new battery cell models can be developed. The price is cheap and the mold opening cycle is short. Some can even be tailored to the shape of the mobile phone to make full use of The battery shell space improves the battery capacity. 7. Good discharge characteristics. Polymer batteries use colloidal electrolytes. Compared with liquid electrolytes, colloidal electrolytes have stable discharge characteristics and a higher discharge platform. 8. The design of the protection board is simple. Because the polymer material is used, 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 be considered to omit the PTC and fuse to save the battery cost. Polymer lithium ion batteries have great advantages in terms of safety, volume, weight, capacity, and discharge performance.
