Tailoring Self‐Catalytic N─Co Bonds into Heterostructure Architectures: Deciphering Polytellurides Conversion Mechanism Toward Ultralong‐Lifespan Potassium Ion Storage (Adv. Mater. 18/2025)

Year: 2025

Type: article

Abstract: Potassium-Ion Batteries In article number 2502894, Shaoming Huang, Wei Zhang, and co-workers reveal a novel self-catalytic conversion reaction mechanism of N-doped CoTe2 composites (N-CoTe2/LTTC) incorporating 3D low-tortuosity tunneling structure, self-catalytic N-Co bonds, and heterojunction. Acting as the anode in potassium-ion batteries, the N-CoTe2/LTTC composite accelerates the catalytic conversion kinetics of potassium polytellurides (K5Te3 and K2Te) and achieves an ultralong-lifespan potassium storage performance over 25000 cycles.
