Antiperovskite materials: advances in synthesis, unique properties, and emerging applications in energy and electronics

Abstract

Perovskites, a prominent category of crystalline substances, have garnered considerable worldwide interest because of their wide range of possible uses and the fascinating fundamental principles they rely on. Antiperovskites (X3BA) are electrically reversed counterparts of perovskites and belong to a category of useful materials. Antiperovskites exhibit distinct physical and chemical characteristics because of their adaptable structural traits derived from perovskites and the abundance of several cations at X sites. Although they are opposites, these analogs have not garnered much attention. Thus, a thorough assessment is needed to spark popular interest. Novel antiperovskite materials display superionic conductivity, superconductivity, notable magnetoresistance, negative thermal expansion, luminescence, and electrochemical energy conversion, among other unique characteristics. The significance of these properties is evaluated based on their impact on advancing material performance, their potential for integration into emerging technologies such as energy storage and electronic devices, and their contribution to addressing global challenges in energy efficiency and sustainability. Assess the possibility of improving performance or creating novel phenomena in antiperovskites in solid-state chemistry by an investigation of the perovskite structure. Antiperovskites are expected to become a growing category of useful materials due to rising research interest.
