Do you know what a polymer lithium ion battery is like?

With the rapid development of communication technology, the successive emergence of mobile phone color screen technology, MMS technology, Bluetooth technology and camera technology puts forward higher requirements on the capacity, volume, weight and electrochemical performance of the battery. The traditional liquid lithium battery has become more and more important. It has become more and more unable to adapt to new demands. The emergence of new polymer lithium batteries (Li-Poly) caters to this demand. Polymer battery is the third-generation lithium battery developed on the basis of the original steel shell and aluminum shell battery. With its lighter, thinner and higher energy density characteristics, it is loved by domestic and foreign communication terminal manufacturers and design companies. . The most fundamental difference between polymer lithium battery and liquid lithium battery lies in the different electrolytes used in the two. The electrolyte of polymer lithium ion battery is solid in appearance, called polymer solid electrolyte. This kind of electrolyte is a kind of polymer material that is in a solid state, but can dissolve and support the electrolyte like a liquid, and can undergo ion migration. Let’s know the eight advantages of using polymer lithium-ion batteries? 1. Good safety performance. Polymer lithium-ion batteries are structured with aluminum-plastic soft packaging, which is different from the metal shell of liquid batteries. In the event of a safety hazard, liquid batteries It is easy to explode, and polymer batteries can only blow up at best. 2. Thin thickness. 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. The polymer cell does not have this problem, and the thickness can be below 1mm. In line with the current demand for mobile phones. 3. The light weight polymer battery is 40% lighter than the steel shell lithium battery of the same capacity specification, and 20% lighter than the aluminum shell battery. 4. The large capacity polymer battery has 10~15% higher capacity than the steel shell battery of the same size specification. It is 5~10% higher than aluminum shell batteries, making it the first choice for color screen mobile phones and MMS mobile phones. 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 below 35mΩ, 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. 6. The shape of the polymer battery can be customized. The thickness of the battery cell can be increased or reduced according to the needs of customers. New battery cell models can be developed. The price is cheap and the mold opening cycle is short. Shell space, increase 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. 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.
