Recent advances in borophene nanosheet for supercapacitor application: Mini review


Borophene, a single-atom layer of boron, has emerged as a novel material that is stronger and more flexible than graphene, drawing significant attention and opening new avenues in the field of supercapacitors due to its excellent electrical, thermal, chemical, and mechanical properties. Borophene exhibits a higher density of states around the Fermi level, primarily originating from the pz orbital rather than px and py orbitals. The Dirac cone of borophene shows enhanced quantum capacitance, surface storage charges, and integrated quantum capacitance, thereby improving its specific capacitance.

This review discusses the theoretical predictions of borophene and highlights its unique properties compared to graphene. It also summarizes various synthesis methods for producing borophene nanosheets, including bottom-up and top-down approaches, along with their advantages and disadvantages. The review covers both theoretical predictions and experimental observations of borophene and its nanocomposites for supercapacitor applications in detail.

Additionally, the review addresses the prospects and challenges associated with developing borophene nanosheets for supercapacitor applications, providing a comprehensive summary of the current state of research in this field.

Summary for Non-Scientists

Borophene is an emerging material that is garnering significant attention in the realm of energy storage, particularly for supercapacitor devices. It consists of a single layer of boron atoms and is notable for its strength and flexibility, surpassing graphene in these aspects. One of the key attributes that makes borophene promising for supercapacitors is its high density of states at the Fermi level, indicating its ability to accommodate a large number of electrons for conducting electricity. This property is primarily attributed to the arrangement of electrons in the pz orbital, distinguishing it from the px and py orbitals.

Furthermore, borophene's Dirac cone demonstrates enhanced quantum capacitance, suggesting its capability to store more charge on its surface—ideal for supercapacitor applications.

The abstract of the review outlines the predictions and distinguishing features of borophene compared to graphene, along with various methods for synthesizing borophene nanosheets, each with its own advantages and limitations. The review also explores theoretical and experimental research on borophene and its composites in relation to supercapacitors, examining future possibilities and addressing the challenges that must be overcome for effective utilization of borophene nanosheets in supercapacitor technology.

In summary, borophene represents an exciting frontier in materials science due to its potential to revolutionize supercapacitors, offering efficient and rapid energy storage capabilities.
