Topological Insulator Bi2Te3 Anode for Aqueous Aluminum-Ion Batteries: Unveiling the Role of Hydronium Ions
The primary scientific challenge in advancing aqueous aluminum-ion batteries (AAIBs) is achieving reversible plating/stripping of the Al metal anode, limited by its low deposition potential (−1.667 V vs SHE) and surface passivation in the aqueous electrolyte. To address this issue, polypyrrole (PPy) decorated topological quantum insulator (Bi2Te3@PPy) is introduced as a novel anode in AAIBs. …
