2. Challenges in Drone Battery Technology
(1) Limited Flight Time and Energy Density
- Most drones rely on lithium-ion (Li-ion) or lithium-polymer (LiPo) batteries, which have energy density limitations.
- Short flight durations (typically 30-45 minutes for commercial drones) restrict mission capabilities.
- Frequent battery swaps and recharges increase operational downtime.
(2) Slow Charging and Battery Lifespan Issues
- Current battery technologies require 30-60 minutes to recharge, reducing efficiency.
- Battery lifespan is limited to 300-500 charge cycles, leading to high replacement costs.
- Overcharging risks can cause degradation and safety hazards.
(3) Weight and Structural Constraints
- Batteries contribute significantly to drone weight, affecting aerodynamics and maneuverability.
- High-capacity batteries increase power-to-weight ratio, requiring larger drones.
- Finding the balance between battery weight and energy output is a key design challenge.
(4) Thermal Management and Safety Risks
- Overheating and thermal runaway can cause battery failure and even combustion.
- Exposure to high temperatures or cold environments affects battery efficiency.
- The risk of short circuits and fire hazards necessitates improved safety features.
