With the use of drones in agriculture, Architecture, logistics, The application of environmental monitoring and other fields continues to deepen, Battery life has become one of the bottlenecks restricting its maximum performance. Especially for industrial drones, The long-term high-intensity flight demand places extremely high demands on the energy density and discharge rate of the battery.

Currently, the majority of drone batteries on the market still rely on traditional lithium battery technology, These batteries have certain limitations in terms of energy density and discharge rate. Despite technological advancements, The battery life has been improved, But for industrial drones that require long flights, Still exists "Range anxiety" .

2. The key to improving battery life: High energy density and high discharge rate

To solve the endurance problem of industrial drone batteries, The core lies in improving the energy density and discharge rate of the battery. Only by increasing the energy output of the battery without increasing its volume and weight, To effectively extend flight time, Simultaneously meeting the high discharge rate requirements of industrial drones.

2. 1 Enhancement of energy density: Technical Practice and Methods

a. Using high-energy density battery chemistry system

at present, Lithium batteries are the most commonly used type of battery in industrial drones, But in terms of improving energy density, Traditional lithium-ion batteries still face certain bottlenecks. In order to increase energy density, Battery manufacturers are adopting more efficient battery chemistry systems, For example, high nickel ternary materials (NCM/NCA) Solid state battery technology.

High nickel ternary material: Compared to traditional cobalt based ternary materials, Nickel based materials can significantly improve the energy density of batteries. The high specific energy characteristic of nickel enables batteries to store more electrical energy under the same volume and weight. Although high nickel ternary batteries have significantly improved energy density, But their stability will face some challenges compared to traditional cobalt based ternary material batteries. Specific issues include poor thermal stability and short cycle life. however, With the advancement of technology, Multiple solutions have been proposed to address these issues, for example:

By optimizing the structure and composition of the positive electrode material, Batteries made of high nickel ternary materials can provide longer flight time in practical applications, Especially suitable for applications such as drones that require extremely high volume and weight.

b. Optimize battery design and structure

In addition to improving battery chemistry materials, Optimizing the structural design of batteries is also an effective way to improve energy density. By improving the internal structure of the battery, For example, using high-density electrode materials and thin film technology, Can further enhance the energy storage capacity of the battery. Specific measures include:

:  Using high specific energy electrode materials: For example, using silicon-based negative electrodes instead of traditional graphite negative electrodes, The theoretical capacity of silicon-based negative electrodes is significantly higher than that of graphite negative electrodes, Can significantly increase the energy density of the battery.

:  Ultra thin battery design: By reducing the size and thickness of battery cells, Add more battery cells within the same volume, Thereby enhancing the overall energy density. The design of thin-film batteries enables them to adapt more flexibly to different models of drones, Further enhance battery life.

c. Solid state battery

Solid state batteries use solid electrolytes instead of traditional liquid electrolytes, This not only enhances the safety of the battery, It can also significantly increase energy density. The energy density of solid-state batteries can theoretically reach twice that of traditional lithium-ion batteries, And it has a longer service life and higher safety. Although solid-state batteries still face certain challenges in terms of technology and production, But it is undoubtedly an important direction for improving the battery life of drones in the future.

2. 2 High discharge rate: Meet high load demands

Apart from energy density, The high load demand of industrial drones during flight also poses higher requirements for the discharge rate of batteries. High discharge rate means that the battery can provide a large amount of power in a short period of time, Support unmanned aerial vehicles to fly for long periods of time under high load conditions.

:  Key technologies for improving discharge rate: By using highly conductive electrolytes and optimizing the current transmission path inside the battery, Can effectively improve the discharge performance of batteries. Targeting the demand for industrial drones, Stable battery chemical composition, Such as nickel cobalt manganese ternary materials (NCM) And lithium iron phosphorus (LFP) , Can provide better charging and discharging performance under high loads, Ensure stable operation of the battery in high load environments.

Through the above technical means, The battery of industrial drones can not only achieve higher energy density, Can also provide stable power support in high load environments, Thus effectively improving the battery life. These technological innovations will greatly promote the widespread application of drones in various industries, Addressing the current range anxiety issue, And pave the way for the future development of industrial drones.
