Advantages of polymer lithium batteries

　　1. Good safety performance: Polymer lithium batteries use aluminum-plastic flexible packaging in their structure, unlike traditional liquid battery cells that use metal casings. This structure prevents the battery from being prone to explosion and other dangerous situations like liquid cells when safety hazards occur. At most, there will only be gas bubbles, greatly reducing safety risks.

　　2. Lightweight and portable:

　　Small thickness: Polymer lithium batteries can be made thinner, breaking through the technical bottleneck of liquid lithium batteries and achieving a thickness of less than 1mm, which can meet the needs of various electronic devices with strict thickness requirements, such as ultra-thin smartphones, smartwatches, etc.

　　Lightweight: It uses polymer electrolyte and does not require a metal shell as a protective outer packaging. It is 40% lighter than steel shell lithium batteries of the same capacity specifications and 20% lighter than aluminum shell batteries. This is a very important advantage for electronic products that pursue lightweight devices, as it can reduce the overall weight of the device and facilitate portability.

　　3. Large Capacity: Polymer lithium batteries have a higher capacity density, with a capacity 10% -15% higher than steel shell batteries of the same size specifications, which can provide longer battery life for electronic devices. And there is still potential for further improvement in its capacity density, with the continuous development of technology, it is expected to achieve higher capacity in the future.

　　4. Low internal resistance: The internal resistance of polymer battery cells is relatively small. Currently, the internal resistance of domestically produced polymer battery cells can even reach below 35m Ω, greatly reducing the battery's self consumption. This can not only improve the energy utilization efficiency of the battery and extend the usage time of electronic devices, but also reduce the heating phenomenon of the battery during charging and discharging, and improve the safety and stability of the battery.

　　5. Customizable shape: Manufacturers can flexibly make polymer lithium batteries into various shapes and sizes according to customer needs, fully utilizing the internal space of the equipment and increasing battery capacity. For example, batteries can be customized according to the shape of devices such as smartphones and tablets to perfectly fit the device.

　　6. Excellent discharge characteristics: Polymer batteries use colloidal electrolytes, which have smoother discharge characteristics and higher discharge platforms compared to liquid electrolytes. This means that the battery can provide more stable voltage and current during the discharge process, ensuring the normal operation of electronic devices, especially for some devices with high power requirements, such as high-end digital cameras, drones, etc., the advantages of polymer lithium batteries are more obvious.

　　7. Long cycle life: Under normal use, the cycle life of polymer lithium batteries can reach over 500 times, which can meet the needs of most electronic devices. And its capacity decay during cyclic charging and discharging is relatively small, and it can still maintain a high capacity after long-term use.

　　8. No memory effect: There is no need to empty the remaining battery before charging, which is convenient to use. Users can charge the battery at any time without worrying about the memory effect affecting the performance and lifespan of the battery.
