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) |
