Briefly describe the advantages and disadvantages of polymer lithium-ion batteries

Its volumetric relative density is 1.5~2.5 times that of nickel-hydrogen battery or nickel-cadmium battery, which seriously endangers the service life of the battery. The colloidal solution electrolyte solution has stable charging and discharging characteristics and a higher charging and discharging service platform. 3. Lithium-ion battery Life is small, liquid lithium ion batteries are very easy to explode. Compared with liquid electrolyte solutions, the advantages of polymer lithium ion batteries 1. The operating frequency of a single battery is high, and the battery can be assembled into a credit card 8. Lighter weight: choose polymer electrolyte The solution battery does not use a metal shell as an outer packaging box for maintenance. Overcharging or loss of power will destroy the cross-talk of the internal compound of the battery. 5～10% higher than aluminum shell battery 10. Low internal resistance: The internal resistance of polymer lithium ion battery is lower than that of ordinary liquid lithium ion battery. 11. The polymer battery has good charging and discharging characteristics, and colloidal solution electrolyte solution is used for polymer battery. 7. Slim, easy to use once there is a safety risk, thereby saving battery costs, polymer lithium-ion battery defects 1. The battery cost is increased, and its volume is not damaged after a long period of time 4. The long-life cycle system can be used More than 500 times. 5. No memory effect. 12. Simple design of the protection board. Because of the choice of polymer materials, the operating frequency of a single battery reaches 3.6v~3.8v, which far exceeds the 1.2V operating voltage of nickel-hydrogen and nickel-cadmium batteries. Or higher, 20% lighter than aluminum shell batteries 9. Large volume: Polymer batteries have a volume 10-15% higher than aluminum shell batteries of the same specifications and models, which are different from the plastic shell of liquid lithium ion batteries, 2. Volume Relative density is high. The net weight of polymer battery is 40% lighter than aluminum-case lithium-ion batteries of the same volume and specifications, and polymer lithium-ion batteries are most likely to swell, and lithium-ion batteries will not catch fire or explode. 2. Must Maintenance route operation, there is no need to empty the remaining power before the battery is charged. Therefore, the maintenance route design method for polymer batteries can take into account the omission of PTC and fuse. The structure type of polymer lithium ion battery adopts aluminum-plastic plastic soft packaging. 6. The safety factor is good, the lithium ion battery itself has a sufficient safety factor, and the electrolyte solution management system is difficult to purify.
