Synergistic effect of ZnO@Bi/C sphere for rechargeable Zn Ni battery with high specific capacity

[email protected]/C sphere with a distinctive core-shell construct is designed and fabricated by using solvothermal method, which is applied as a novel electrode material of ZnNi battery for the first time. The analytical results manifest that the core of the [email protected]/C sphere coated with carbon layer consists of a large number of ZnO nanoparticles (NPs), and in situ modified metal Bi is embedded in the amorphous carbon layer and ZnO NP...
