Key Features – Semi-Solid UAV Battery
High Energy Density (224Wh/kg): Delivers 224Wh/kg gravimetric energy density – significantly higher than conventional LiPo batteries (typically 160–220 Wh/kg) – extending UAV flight time without adding weight. Semi‑solid technology minimizes electrolyte usage, suppresses dendrite growth, and extends cycle life.
High Capacity (40Ah / 148Wh): 3.7V nominal voltage with 40Ah capacity delivers substantial energy for long‑endurance missions – mapping, surveying, inspection, and cargo delivery.
High Discharge Rate (5C Continuous / 7C Pulse): 5C continuous discharge (200A) and 7C instantaneous pulse discharge (280A) for power‑intensive flight maneuvers, takeoff, and emergency power. Semi-solid batteries with 5C discharge capability are well-suited for industrial drones requiring both endurance and power.
Long Cycle Life (1000 Cycles): 1000 cycles at 80% depth of discharge ensures reliable performance over extended operational periods, outperforming many traditional Li‑ion batteries in long‑term usability.
Semi‑Solid Safety: Hybrid electrolyte architecture with advanced materials suppresses lithium dendrites and provides enhanced safety, significantly reducing leakage and thermal runaway risks.
Wide Operating Temperature Range: Supports charging from 0~45°C and discharging from -20~60°C for versatile mission scenarios across diverse environments.
Ultra‑Low Internal Resistance (≤1.2mΩ): Minimizes heat generation and power loss during high-rate discharge, improving efficiency and safety.
