In the rapidly evolving landscape of modern warfare, the demand for reliable, high-performance power sources for projectile-borne electromechanical systems has never been greater. A recent study published in *Green Energy and Intelligent Transportation* (《绿色能源与智能交通》) sheds light on the critical challenges and technological advancements in this field, offering insights that could reshape the future of military and commercial energy solutions.
The research, led by Da Yu of the ZNDY of Ministerial Key Laboratory at Nanjing University of Science and Technology, explores the complexities of powering smart ammunition and precision-guided munitions. These systems, often referred to as the “decision-makers” of modern warfare, require robust energy sources capable of withstanding extreme conditions—from high overloads and centrifugal forces to ballistic aerothermal effects and central blast impacts.
“Munition-borne power sources are the backbone of smart ammunition,” Yu said. “They must endure extreme environments while delivering consistent performance, making them a critical area of focus for defence research.”
The study compares three primary energy sources: liquid reserve batteries, solid-state thermoelectric batteries, and supercapacitors, each with distinct advantages and limitations. Liquid reserve batteries, for instance, offer high energy density but face challenges in rapid activation and environmental adaptability. Solid-state thermoelectric batteries excel in stability but struggle with efficiency in extreme conditions. Supercapacitors provide quick energy delivery but lack the sustained power output required for long-duration missions.
Yu’s research highlights the need for innovative solutions to address these challenges, including the development of non-reserve primary batteries, non-bottle-breaking reserve batteries, and new system batteries. The study also proposes design approaches such as elastic skeleton structures and high-pressure sealed secondary packaging to enhance durability and performance.
One of the most compelling aspects of the research is its potential commercial applications beyond the defence sector. The energy solutions developed for projectile-borne systems could be adapted for use in aerospace, automotive, and industrial applications, where reliability and performance under extreme conditions are equally critical.
“The lessons learned from munition-borne power sources can be applied to other high-demand energy sectors,” Yu said. “This research is not just about defence—it’s about pushing the boundaries of what’s possible in energy storage and delivery.”
As nations around the world invest heavily in advanced military technologies, the findings from this study could accelerate the development of next-generation power solutions. By addressing the weak links in current systems, researchers and engineers can pave the way for more resilient, efficient, and adaptable energy sources that meet the demands of both military and civilian applications.
In an era where energy security is paramount, the insights from Yu’s research offer a roadmap for innovation, ensuring that the power systems of tomorrow are as advanced as the technologies they support.
