AI Technical Summary
Existing selenide-based electrode materials suffer from problems such as small specific surface area, low actual specific capacity, poor rate performance and cycle stability, and complex preparation process, which is not conducive to large-scale application.
Using Co-MOF rod array material as a precursor, hollow CoSe2 material is formed through selenization treatment, and Ni3Se4 and Ni(OH)2 coating layers are formed in solvothermal reaction to prepare selenide-based superstructured nanoarray material with hollow and layered core-shell superstructure.
This improves the specific surface area and electrochemical activity of the material, providing excellent electrochemical performance. It can be directly used as the working electrode of alkaline zinc-ion batteries in large-scale preparation, thereby enhancing the energy density and stability of the battery.
