Synthesis and Modification of Boron Nitride Nanomaterials for Electrochemical Energy Storage: From Theory to Application

Abstract As a conventional insulating material, boron nitride (BN) has been mainly investigated in the electronics field. Very recently, with the development of preparation/modification technology and deeper understanding of the electrochemical mechanisms, BN‐based nanomaterials have made significant progress in the field of electrochemistry. Exploiting the characteristics of BN for advanced electrochemical devices is expected to be a breakthrough that will stimulate a new energy revolution. Owing to its chemical and thermal stability, as well as its high mechanical strength, BN can alleviate various inherent problems in electrochemical systems, such as thermal deformation of conventional organic separators, weak solid electrolyte interface layers of metal anodes, and electrocatalyst poisoning. The integration of BN with various electrochemical energy technologies is systematically summarized from the perspectives of material preparation, theoretical calculations, and practical applications. Moreover, the challenges and prospects for the future development of BN‐based electrochemistry are highlighted.
