The scale of China's drone market has maintained rapid growth, and the industrial grade drone market is growing rapidly. Due to its advantages in vertical takeoff and landing, long-distance operation, hovering operation, and high speed operation, the vertical takeoff and landing fixed wing unmanned aerial vehicle is currently widely used in emergency rescue, security warning, aerial surveying and mapping, water area supervision, and other fields. The operational characteristics of vertical takeoff and landing (VTOL) unmanned aerial vehicles (UAVs), such as vertical takeoff and landing (VTOL) and long endurance, require higher requirements for UAV batteries, taking into account both battery energy density and power performance.

The laboratory has developed an energy based drone battery to meet the special requirements of battery energy density and instantaneous power for vertical takeoff and landing drones. Through optimization of battery design and process, the current discharge energy density of single cell batteries at room temperature of 2C reaches 258 Wh/kg, which is 10% higher than that of commercial drone batteries; 1C/2C room temperature cycling for 950 cycles, with a capacity retention rate of 86.9% and excellent cycling performance; The discharge capacity ratio of 2C/1C is 98.8%, and the discharge capacity ratio of 5C/1C is 96.4%, demonstrating excellent rate performance. This battery not only has high mass energy density, excellent cycling performance, but also good rate performance, meeting the continuous constant current discharge of 10C, and meeting the operational requirements of vertical takeoff and landing drones.
