“In the field of aqueous zinc ion batteries, researchers have prepared bismuth telluride nanostructured materials using a one-step hydrothermal method and applied them for the first time to the positive electrode of the battery. Through synchrotron radiation in-situ X-ray diffraction technology, the highly reversible proton intercalation phenomenon during the reaction process of bismuth telluride nanosheets was observed in real time, confirming the reversible transport characteristics of protons in bismuth telluride positive electrode materials.”
