Main Advantages

High Energy Density and Significantly Extended Battery Life

Energy Density: 320-400 Wh/kg (Traditional lithium polymer batteries: approximately 180-220 Wh/kg). For the same battery life: Battery weight can be reduced by 30%+, allowing for a larger payload.
Significantly Improved Safety

Gel Electrolyte (Semi-Solid): Electrolyte content is only 5-10%, making it less prone to leakage and flammability. Needle Penetration/Extrusion: No open flame, no explosion, thermal stability ≥300℃
Wide Temperature Range

Operating Range: -30℃～+80℃, stable for high-altitude/winter operations. -20℃ Environment: Capacity retention ≥85% (Traditional liquid lithium batteries: only 50-60%). Winter Battery Life Decrease: Reduced from 35% to ≤12%, making it more practical in northern/high-altitude regions.
Longer Cycle Life and Lower Overall Cost

Cycle Count: 1200-2000. Low self-discharge and minimal degradation: More stable for long-term storage, suitable for long-endurance, high-frequency operations.
Moderate Discharge Rate

Continuous discharge: 5-10C, balancing long-term cruise and short-term high-maneuverability (climbing, wind resistance). Low internal resistance and low heat generation: Low temperature rise during long-term flight, further improving safety and lifespan.
Soft-pack Polymer Form

Aluminum-plastic film soft pack: Customizable to fit the fuselage space and optimize the center of gravity. Thin design: 20-30% smaller volume than traditional lithium batteries of the same energy.
