A Bi2Te3/Te heterojunction cathode with an insertion/conversion dual-mechanism for high-capacity aqueous zinc-ion batteries.
The topological insulator Bi2Te3 has attracted significant attention in zinc-ion batteries (ZIBs) due to its unique quantum effects and high theoretical capacity. However, its practical application is hindered by the severe volume expansion during Zn2+ insertion/extraction and sluggish reaction kinetics. Herein, we rep...
