UAVs and the Future of Battery Manufacturing
Overview Unmanned Aerial Vehicles (UAVs) or drones are dramatically transforming medical, military, personal use and commercial industries. With the rapid growth of UAVs, the demand for powerful and enduring batteries has escalated, accelerating parallel advancements in battery manufacturing. Batteries for UAVs must be highly-efficient, lightweight, and have longer life spans. This guide provides an insight into the relationship between drones and the future of battery manufacturing, focusing on the progress, challenges, and necessary improvements in battery technology.
Advancements in Battery Manufacturing for UAVs In the past decade, the market for drones has seen an explosive growth. From a market size of $18.14 billion in 2018, the global drone market is set to reach $42.8 billion by 2025, according to a report by Fortune Business Insights. Moreover, the global battery market is anticipated to surge from $92.6 billion in 2020 to $116.5 billion by 2027, as stated by Business Wire. This growth is largely pinned with the increasing demand for UAVs, thus reflecting the development in battery technologies. Technological advancements in battery manufacturing, like Lithium-ion and Lithium-polymer batteries, have hugely impacted the performance of UAVs. These batteries offer high energy-density, lightweight, and can be crafted in flexible shapes, which is ideal for varied UAV designs.
Challenges Faced in Battery Manufacturing However, despite the advancements, there are still obstacles in battery manufacturing that limit the performance of UAVs. The main challenge is extending the flight time of drones — currently, a typical UAV can fly for around 15-30 minutes after which a battery change or charging is required. Another hurdle is reducing the weight of batteries without compromising their power capacity. Researchers suggest that for every 1% increase in battery weight, the drone's flight time decreases by approximately 0.64%. Further, there are safety concerns connected to battery overheating. These demands for longer flight time, lighter weight, and safer operations call for continued improvements in battery manufacturing.
Prospective Improvements in Battery Manufacturing In the quest to optimize drone functionality, companies are investing heavily in advanced technologies, around $17 billion each year according to CB Insights. Some of the ongoing developments include designing batteries with high energy density, using energy-dense and fast charging materials, improving drone energy efficiency, and adopting artificial intelligence to monitor battery performance to prevent overheating. There are also potential breakthroughs in solid-state and hydrogen fuel cell batteries, which could potentially offer longer flight time and higher safety levels.
