one,What is a polymer lithium battery?
Polymer lithium battery is a lithium ion battery using polymer electrolyte. Compared with traditional liquid electrolytes, polymer electrolyte has a variety of obvious advantages such as high energy density, smallerized, ultra -thin, lightweight, and high safety and low cost.
The polymer lithium battery has become a routine choice for small -sized rechargeable batteries. The small and light development trend of radio equipment requires the rechargeable battery to have higher energy density, and the awakening of global environmental awareness also puts forward the requirements of the battery that meets environmental protection.
Second, polymer lithium battery naming
The polymer lithium battery is generally named for six to seven digits, which indicates that thick/width/height, such as PL6567100, indicating that the thickness is 6.5mm, the width is 67mm, and the height is 100mm lithium battery. Protocol. The polymer lithium battery manufacturing process is generally used for soft packaging, so the size changes are very flexible and convenient.
Third, the characteristics of polymer lithium battery
1. High -energy density
The weight of the lithium polymer battery is half of the same capacity nickel-cadmium or nickel-metal hydride battery. The volume is 40-50%of nickel-cadmium, and 20-30%of nickel-metal hydride.
2. High voltage
The operating voltage of a lithium polymer battery monomer is 3.7V (average), which is equivalent to three series nickel -cadmium or nickel -hydride batteries.
3. Good safety performance
The outer packaging is packed by aluminum -plastic, which is different from the metal shell of liquid lithium battery. Due to the use of soft packaging technology, hidden dangers of internal quality can be displayed immediately through the deformation of the outer packaging. Once a safety hazard occurs, it will not explode and it will only swell.
4. Long circulation life
Under normal conditions, the charging cycle of lithium polymer batteries can exceed 500 times.
5. No pollution
Lithium polymer batteries do not contain harmful metal substances such as cadmium, lead, and mercury. The factory has passed the ISO14000 environmental system certification, and the product is in line with the EU ROHS instructions.
6. No memory effect
The memory effect refers to the decrease in the battery capacity during the charging and discharge cycle of nickel -cadmium batteries. There is no such effect in the lithium polymer battery.
7. Fast charging
A constant current constant voltage voltage capacity with a rated voltage of 4.2V can make the lithium polymer battery get a full charge within one or two hours.
8. Complete models
The model is complete, with a wide range of capacity and size. It can be designed according to customer needs. A single thickness is 0.8 to 10mm, and the capacity is 40mAh to 20AH.
Fourth, the application of polymer lithium battery
Because polymer lithium batteries have excellent performance, it is widely used in mobile devices, smart watches and other electronic products. In addition, due to its high safety, longevity and high energy density, it is also widely used in the fields of energy storage systems, electric vehicles and drones.
5. The difference between polymer lithium batteries and lithium batteries
1. Different raw materials
The raw materials for lithium -ion batteries are electrolyte (liquid or colloid); the raw materials of the lithium battery of the polymer are electrolytes with polymer electrolytes (solid or glue state) and mechanical electrolyte.
2. Different security
Lithium -ion batteries are easy to explode in high -temperature and high -pressure environments; polymers lithium batteries use aluminum -plastic films as shells. When the inside is used, the liquid is not exploded even if the liquid is very hot.
3. Different shape
The polymer battery can be thin, any area and arbitrary shape, because its electrolyte can be solid, glue, and not liquid. The lithium battery uses an electrolyte. Essence
4. Different battery voltage
Because the polymer battery uses polymer materials, it can be made into a multi -layer combination in the battery cell to achieve a high voltage, and the lithium battery battery cell is said to be 3.6V. If you want to reach high voltage in actual use, multiple multiple needs to be multiple. The battery series can be connected together to form an ideal high -voltage work platform.
5. Different manufacturing process
The thinner the polymer battery is, the better the lithium battery, the thicker the lithium battery, the better the production, which makes the lithium battery expand the field more.
6. Capacity
The capacity of polymer batteries has not been effectively increased, and it is still reduced compared with the standard capacity of lithium batteries.
