Advantages and Practical Applications of Polymer Lithium Batteries in the Drone Industry


As the drone industry continues to evolve, polymer lithium batteries have emerged as the preferred choice for powering drones. But what advantages do polymer lithium batteries offer as drone batteries, and how are they utilized in practical applications?

  1. Flexibility in Size and Shape: Polymer lithium batteries are not restricted to standard sizes and can be flexibly designed in various dimensions, including thickness. Unlike conventional liquid lithium-ion batteries, polymer batteries can be as thin as 1mm, allowing for more versatile design options and maximizing the use of valuable space in drones.

  2. Enhanced Discharge Performance: With gel electrolytes, polymer lithium batteries exhibit more stable discharge characteristics compared to liquid electrolytes. This results in approximately 20% higher energy density and superior capacity compared to conventional lithium-ion batteries, making them ideal for powering drones.

  3. Lower Internal Resistance: The gel electrolytes used in polymer lithium batteries contribute to lower internal resistance. This translates to reduced self-discharge and extended standby time, enabling drones to deliver higher performance. Leading manufacturers like CTECHI have achieved industry-leading levels of internal resistance in their polymer lithium batteries.

  4. Enhanced Safety Features: Polymer lithium batteries, with their aluminum-plastic soft packaging, have a lower risk of explosion compared to batteries with metal casings. In case of a safety hazard, they are more likely to swell rather than explode, ensuring a higher level of safety for drones and their operators.

  5. Lightweight Design: By eliminating the need for metal casing, polymer lithium batteries are lighter compared to batteries of similar capacity. This lightweight design is advantageous for drones, allowing for longer flight times and improved overall performance.

One notable example of a polymer lithium battery designed for industrial drones is the 14S30Ah intelligent battery produced by CTECHI. This battery offers several features tailored to the needs of industrial drone users:

  1. High Capacity and High Rate: The battery integrates high-density lithium polymer cells with high-rate compatibility, providing both safety and exceptional performance. With dimensions of only 176mm x 102mm x 227.5mm and a weight of 6.5kg, it delivers a remarkable energy capacity of 1554WH.

  2. Real-Time Data Display: Equipped with a built-in display screen, the battery provides instant access to various flight data and parameters, enabling users to monitor performance and analyze flight records conveniently.

  3. Zero-Power Consumption Display Screen: The display screen consumes zero power, ensuring minimal impact on battery life. Its high-definition, high-contrast design ensures readability even in bright outdoor conditions.

  4. spower System for Enhanced Data Support: The battery's unique spower system allows users to access detailed battery information, including location, voltage, and trajectory, through a cloud platform. Additionally, it provides safety alerts in real-time via multiple communication channels, ensuring the safe storage and use of each battery cell.

In summary, polymer lithium batteries offer significant advantages for powering drones, including flexibility, enhanced performance, safety, and lightweight design. Manufacturers like CTECHI are continuously innovating to meet the evolving needs of the drone industry.
