Honeycomb‐based heterostructures: An emerging platform for advanced energy applications: A review on energy systems

Abstract

AbstractDue to their promising properties such as low corrosion resistance, excellent strength, high‐temperature operation, simple formability and machining, and, most importantly, cost‐effectiveness in the industry, honeycomb‐based heterostructures have been widely used as energy storage and conversion systems for decades. Despite their low density, honeycomb structures also have strong out‐of‐plane compression and shear properties, resulting in very high unique strengths. The honeycomb‐based molded structure, which was inspired by bee honeycombs and provides a material with low density and high out‐of‐plane compression and shear properties, has found widespread use and now plays a critical role in energy conversion and storage technologies such as lithium‐ion batteries, solar cells, and supercapacitors. These materials have a lot of promise in terms of addressing and environmental concerns regarding power sources at a time when global energy demand is skyrocketing. In light of this, we contend in this research paper that complex honeycomb‐based architectures outperform conventional simple 2D designs in a wide variety of technological applications. We also go into the different synthetic methods used to make honeycomb structures and look at how these novel materials may be used for long‐term electrochemical energy transfer and storage. Finally, the current challenges and opportunities for the construction of honeycomb systems are discussed, as well as new research directions.
