Highly Conductive Tellurium and Telluride in Energy Storage

Enhancing energy/power density of electrochemical energy storage devices is a hot topic in the present-day science community. The electrochemical performance of these devices is strongly bound by the fundamental nature of the electrodes in terms of reaction mechanism, crystal structure, electrons/ions transfer kinetics and so on. These features are also the main challenge for the previously investigated electrodes (e. g. carbon, metal oxides/sulfides). Recently, tellurium and telluride-based materials have aroused increasing interest in the energy storage field due to their high electronic conductivity, conducive crystal structure, and superior volumetric capacity. To provide a better understanding of the fundamental properties and energy storage performance of tellurium and telluride-based materials, we first introduced the various physical-chemical properties of telluride-based materials. Then, we summarize the latest research advances in the field of energy storage with these materials, including essential physical-chemical properties, synthetic methods, design strategies, and electrochemical performances. The future perspectives and challenges of tellurides aiming for practical application are discussed at last.
