What are the advantages and disadvantages of polymer lithium ion batteries

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 and ultra-thin, and the battery can be assembled into a credit card. Ordinary 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 below 1mm, which meets the needs of current mobile phones. direction. 3. The battery with light weight and polymer electrolyte does not need a metal shell as a protective outer packaging. The weight of a polymer battery is 40% lighter than a steel shell lithium battery of the same capacity and 20% lighter than an 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 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. Manufacturers are not limited to the standard shape, and can be economically made into a suitable size. Polymer batteries can add or reduce the thickness of the battery cell according to the needs of customers, and develop new battery cell models. They 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 battery shell space and improve 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 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, thereby saving battery costs.
