Bimetallic tellurides electrodes: From synthesis to applications in energy storage and conversion

The rapid growth in global energy demand has necessitated the development of efficient energy storage and conversion devices, with the aim of enhancing grid stability, promoting the adoption of electric vehicles, and powering portable electronics. However, the performance of these devices is constrained by the limitations of traditional electrode materials and catalysts. Bimetallic tellurides have emerged as a promising solution due to their exceptional synergistic effects, high electronic conductivity, abundant redox-active sites, and outstanding electrochemical stability. Nevertheless, achieving cost-effective synthesis and stable applications remains a significant challenge. Hence, the most recent advances of bimetallic tellurides electrodes from synthesis to application are systematically reviewed. Several synthetic strategies for exquisite bimetallic tellurides nanostructures, including tellurization, ball-milling, solvo/hydrothermal, electrodeposition, wet chemical, and template method, are discussed. Moreover, the applications of bimetallic tellurides are extensively summarized in energy storage and conversion devices, which include alkali metal-ion batteries (Li-ion, Na-ion, and K-ion), supercapacitor, hydrogen evolution reaction (HER), and oxygen evolution reaction (OER). Besides, the challenges and potential solutions of bimetallic telluride for energy applications are also suggested. This work provides fundamental insight and guidelines for the future design of bimetallic tellurides in energy storage and conversion technologies.
