About Anode free Cells
High-Performance Power | Self-developed | Superior Performance
The semi-solid battery represents an emerging battery architecture.
Compared to conventional lithium-ion batteries, semi-solid batteries deliver higher energy density and superior thermal stability. They are widely adopted in industrial drone battery systems, robotics, and other advanced applications.
Comparison of Joysun semi-solid vs. liquid Li-ion cells:
| Joysun Anode free battery | Semi-Solid State | tradition UAV Li-ion | |
| Energy Density | Up to 600+Wh/kg | ~350–400 Wh/kg | 180~260Wh/kg |
| Weigh | ~40–50% lighter | ~20–30% lighter | Baseline |
| Cycle Life | 10~20cycles | 800–1500 cycles | 500–1000 cycles |
| Low-Temp Performance | Better(-40~60℃) | Better(-40~60℃) | Fair |
| safety | Excellent (Near non-flammable) | Excellent (Near non-flammable) | Moderate (thermal runaway risk) |

or submit your requirements to receive tailored energy solution from our professional team.
FPV Battery
FPV is a special type of drone, primarily characterized by its unique first-person-view flight experience. Based on usage, FPV drones are categorized into several types, including Drone Racing, Freestyle, CineFPV, and FPV aerial photography.
Joysun offers a diverse range of battery options for all types of FPV drones, with discharge rates 3C ~ 200C. Both LiHV and standard LiPo chemistries are available.
Industrial UAV
Industrial drones are UAVs designed for professional operations. They are typically larger in size and mostly multi-rotor, featuring a payload mounting structure underneath and tall landing gear. These drones demand high levels of protection and extended flight endurance.
Joysun provides high-energy-density batteries for this type of drone, with a maximum energy density of up to 550 Wh/kg, enabling significantly longer flight times.
Radio Control model
RC model batteries represent a very broad product category. They cover remote control cars, boats, aircraft, robots, and more, characterized by an extremely wide size range and a high degree of DIY flexibility.
Joysun primarily provides power solutions for electric RC models, offering cost-effective customization options ranging from 3C to 200C, along with batteries in a wide variety of sizes and specifications.
Humanoid robots
Humanoid robots have become a hot topic in recent years. Joysun provides highly customized pouch cell battery solutions for this type of robot, featuring specialty cells with an energy density of over 400 Wh/kg and a low risk of thermal runaway.
Car Jump Starer
A car jump starter is a common emergency tool for drivers. It is primarily used to power a vehicle's battery, and typically integrates multiple functions to handle various situations that may arise on the road.
Joysun's car jump starter delivers reliable discharge performance even at -20°C, and integrates an air compressor, flashlight, phone charging, BMS, and more. It is the ideal travel companion for drivers.
Home Energy Storage System
A home energy storage system is a battery solution designed for off-grid backup power, solar energy integration, and peak shaving and valley filling. It typically features an all-in-one wall-mounted design or a modular stackable configuration, with a total capacity that can reach 20 kWh or even higher.
For home energy storage systems, Joysun offers integrated energy storage cabinets as well as customized solutions.
