What is it about?

The demand for energy continues to surge, and traditional batteries are struggling to keep pace. To address this challenge, we are at the forefront of developing next-generation batteries. These advanced energy storage solutions offer superior performance, greater energy density, and enhanced safety compared to conventional batteries. They harness state-of-the-art materials and technologies to overcome the limitations of existing energy storage systems. Our research focuses on a remarkable material known as borophene aerogel, and our innovative approach promises stable and high-performance batteries. These batteries exhibit the capacity for increased energy storage, extended lifespans, faster recharging, and enhanced cost-efficiency. Our work not only pushes the boundaries of battery technology but also holds the potential to revolutionize a range of energy conversion applications, from hydrogen storage to supercapacitors and sensors.

Why is it important?

we demonstrate, for the first time in the literature, an original and exciting method for producing borophene aerogel. This method is highly generic and very powerful, in which we were and uses hexagonal boron nitride aerogels as a template and protection layer for borophene. In this way, we were able to eliminate severe instability and oxidization issues, typical of borophene. Our aerogels are very stable, providing us with the ability to produce very high performance next generation batteries including Na-ion, Mg-ion, Ca-ion and Li-S batteries. To the best of our knowledge, our cells are among the highest performing battery cells in the literature. We believe the findings in this brief report are very important, with the potential to be one of the key elements in unlocking a variety of other breakthroughs in energy conversion devices to achieve superior batteries in the future. Additionally, this research has the possibility to generate a significant synergy that will assist other researchers in moving forward to create cutting edge device geometries including hydrogen storage, supercapacitor, sensors, etc.


The significance of aerogel technologies in shaping the future of battery development cannot be overstated. Notably, borophene aerogel and boron nitride aerogels hold the key to advancing energy density and safety in batteries. However, the current landscape reveals a reluctance among major battery manufacturers to embrace substantial changes, with a preference for incremental adjustments. This stance has, unfortunately, led to the oversight of numerous promising technologies by both startups and investors who tend to follow the industry leaders. Those who dare to incorporate aerogel technologies into their battery architectures and chemistries are poised to be the trailblazers that dominate the market in the next five years. Their forward-thinking approach ensures that their batteries not only meet the growing energy demand but also address safety concerns effectively. In this paper, we provide a glimpse of the remarkable potential inherent in aerogel technologies, highlighting their transformative power in the realm of energy storage.
