As UAV application scenarios continue to deepen, battery technology is undergoing a paradigm shift from a single energy supply device to an intelligent power system. Enov's innovative practice shows that through the deep integration of material science (e.g., high-nickel cathode, solid-state electrolyte) and digital technology (intelligent BMS, predictive maintenance), UAV batteries have made breakthroughs in energy density, environmental adaptability, and economy. Looking ahead, the commercial application of solid-state batteries will push the endurance beyond the 2-hour mark, while the development of hydrogen fuel cells may revolutionise the energy supply model. These technological advances will not only reshape the consumer drone market, but also bring revolutionary changes to professional fields such as industrial inspection, emergency relief, and smart logistics. It is suggested that all parties in the industry chain pay close attention to key nodes such as the mass production process of solid-state batteries and the construction of intelligent fast charging networks, and jointly promote the UAV industry into the next stage of development.
