With the rapid development of technology, drones have gradually penetrated into various industries. From military reconnaissance to aerial photography to logistics and distribution, the application scenarios of drones are constantly expanding. In this process, polymer lithium batteries, as a new type of energy storage device, have gradually become the preferred battery in the drone industry due to their unique advantages and wide application prospects.

1. Advantages of polymer lithium batteries

High Energy Density
The energy density of polymer lithium batteries is usually between 200~260Wh/kg, which allows them to provide drones with greater cruising range and longer flight time. In comparison, traditional lithium-ion and nickel-metal hydride batteries have low energy density and cannot meet the growing energy needs of drones.

High charge and discharge rate
Lithium polymer batteries support high rate charge and discharge, which means they can provide a large amount of energy to the drone in a short period of time. This is crucial for application scenarios that require fast response and high-efficiency output (such as aerial photography, logistics and distribution, etc.).

Low Internal Resistance
Polymer lithium batteries have very low internal resistance, which means less energy is lost during charging and discharging, thereby improving the overall efficiency of the battery. In addition, low internal resistance also helps reduce heat generation and improve battery safety performance.

Flexible shapes
Lithium polymer batteries can be customized into various shapes and sizes according to actual needs, which allows them to easily adapt to different models and specifications of drones. In contrast, traditional lithium-ion batteries and nickel-metal hydride batteries have relatively fixed shapes and are difficult to meet the diverse needs of drones.

Good safety performance
Polymer lithium batteries use solid electrolytes instead of traditional liquid electrolytes, which makes them less likely to leak or explode under high temperatures or external forces. In addition, polymer lithium batteries also have high overcharge protection capabilities, effectively reducing safety hazards caused by overcharge.

2. Practical application of polymer lithium batteries in the drone industry

Consumer-grade drones
Consumer-grade drones are mainly used in aerial photography, leisure and entertainment and other fields. These drones have high requirements on battery weight and volume, and polymer lithium batteries just meet this demand. At the same time, the high energy density and high charge and discharge rate of polymer lithium batteries also provide longer flight times and faster response times for consumer drones.

Industrial application drones
Industrial application drones involve agricultural plant protection, logistics and distribution, security monitoring and other fields. These drones have stricter battery performance requirements, and the advantages of polymer lithium batteries are fully reflected in these fields. For example, in the field of agricultural plant protection, polymer lithium batteries can provide stable energy output for drones to ensure that they maintain high efficiency during long-term operations; in the field of logistics and distribution, polymer lithium batteries can help improve the efficiency of drones. The aircraft's load capacity and flight distance can be expanded to expand the delivery range and improve delivery efficiency.

Military Drones
Military drones have extremely high safety requirements for batteries. Lithium polymer batteries have become an ideal choice for military drones due to their excellent safety performance and stability. In addition, the shape flexibility of polymer lithium batteries also helps military drones achieve miniaturization and stealth design, improving their battlefield survivability.

In short, polymer lithium batteries have become the preferred battery in the drone industry with their unique advantages and wide application prospects. With the continuous advancement of technology and the continuous expansion of application scenarios, we have reason to believe that polymer lithium batteries will play a more important role in promoting the continued innovation and development of the drone industry in the future.
