What are the advantages of Solid-state Lithium ion batteries?

Drone power technology continues to make breakthroughs. This new technology, positioned between liquid lithium batteries and all-solid-state batteries, is disrupting the traditional lithium battery landscape with its multidimensional advantages, injecting new momentum into the low-altitude economy.

Doubled Energy Density: Dual Breakthroughs in Endurance and Payload

Lithium polymer batteries commonly used in consumer drones typically have energy densities below 250Wh/kg, while liquid lithium batteries in agricultural crop protection drones rarely exceed 300Wh/kg.

Solid state batteries achieve a qualitative leap through material innovation. Combining silicon-carbon anodes with high-nickel cathodes, they reach 350Wh/kg—nearly doubling traditional energy density. This enhancement directly translates to operational capability.

Environmental Adaptability: Stable Output at -40°C

Through optimized electrolyte formulations, semi-solid batteries overcome temperature limitations. ZYEBATTERY products operate stably between -40°C and 60°C, maintaining 85% capacity retention in extreme cold. In contrast, conventional lithium batteries last only 15 minutes under identical conditions, failing to meet demands for high-altitude rescue operations or polar expeditions.

Cycle Life Advantages

By suppressing lithium dendrite growth, semi-solid batteries extend cycle life to over 1,000 cycles. Some models retain over 80% capacity after 1,200 cycles.

For agricultural drones charging/discharging three times daily, traditional batteries require two annual replacements, while semi-solid batteries operate continuously for 12 months—reducing annual costs by 60%.

As drone technology advances, battery classifications continue to refine. For instance, novel solid-state batteries are gradually entering the consumer market and may emerge as a new classification category in the future.

Understanding battery classification standards not only helps users select products accurately but also enhances comprehension of the matching logic between battery performance and drone applications, enabling more efficient and safer drone operation.

Drones and Batteries: Proper Selection Unlocks More Possibilities

For consumer-grade drones used in everyday aerial photography, these typically feature lightweight designs with relatively limited flight altitudes and ranges. They require batteries that offer portability and sufficient endurance. Generally, lithium batteries with capacities between 2000mAh and 5000mAh are suitable choices, providing flight times of approximately 20 to 40 minutes—adequate for most daily photography needs.

LiHV Batteries

LiHV represents a distinct type of LiPo battery, where HV (high voltage) denotes its higher voltage rating. These batteries offer greater energy density than traditional LiPos and can be charged up to 4.35V per cell. However, opinions vary regarding LiHV lifespan, as their performance may degrade faster than standard LiPos.

Flight Style Influences Battery Choice

If you plan to fly consistently above 50% throttle, you'll likely need a higher C-rate. That's right—you must consider what kind of flying you intend to do and whether weight or capacity is more important to you. Hardcore racers will need the lightest battery sufficient to complete the race course. But for “freestyle players,” weight isn't the sole priority, and larger batteries can be used for longer flight times.
