The drone industry has seen a boom in recent years, but one major hurdle remains: short flight times. This limits the potential applications and keeps many operators grounded. This three-part blog series will explore companies actively working on extending drone flight times through innovative battery solutions.
Powering Up: A Look at Drone Battery Options
Before diving into the companies, let's take a quick pit stop to understand the heart of the drone - its battery. Drones typically rely on high-performance lithium batteries, chosen for their lightweight design, high energy density, and ability to handle high currents. The battery's performance directly affects flight time, speed, and stability.
Here are some common battery types for drones:
Lithium Polymer (LiPo): A popular choice for hobbyists and consumers due to their high energy density, translating to longer flight times. They're lightweight and come in various sizes and voltages, making them versatile for different drones.
Lithium-Ion (Li-ion): Less common in consumer drones, Li-ion batteries offer similar energy density to LiPo but may have different charging and handling requirements. They're often found in professional or industrial drones where longer flight times or specific safety features are needed.
Solid-State: Still under development, solid-state batteries hold immense promise for the future. They offer potentially higher energy density, improved safety, and longer lifespans, making them ideal for demanding drone applications.
The Innovators: Companies Extending Drone Flight Time
While the list is vast, here are a few companies leading the charge in drone battery advancements:
Rose Batteries: Focused on FAA-approved batteries, Rose Batteries leverages its engineering expertise to create custom solutions for air, sea, and land drones. They work with all major battery technologies, with a focus on lithium-ion, and pride themselves on sophisticated Battery Management Systems (BMS).
Fullymax: This high-volume lithium polymer battery manufacturer (producing 55 million cells annually!) offers custom battery solutions for various applications, including agricultural drones, aerial photography, and cargo delivery. Their UAV Battery boasts a long cycle life and excellent performance for outdoor use, while their UAV Smart Battery features an LCD screen for real-time battery information, perfect for tasks like mapping and environmental monitoring.
Amprius Technologies: Amprius takes things a step further by utilizing silicon instead of carbon in their SiMaxx batteries. This innovative approach allows for up to 200% greater run time compared to traditional batteries. For example, a drone using a carbon anode battery might fly for 24 minutes, whereas a SiMaxx battery could extend that flight time to 42 minutes!
Stafl Systems: Looking to push the boundaries in electric vehicles, Stafl Systems designs and manufactures a wide range of battery packs and BMS systems. Their high-voltage lithium-ion packs are built for various applications, even in harsh environments. Recently, Stafl partnered with Amprius to integrate SiCore cells into their advanced battery packs, aiming to set a new industry standard for performance and reliability in electric mobility, including UAV (Unmanned Aerial Vehicle) and UAM (Urban Air Mobility) applications.
