Abstract SnO2@ZnO was synthesized by a new method involving the immobilization of Sn onto zeolitic imidazolate framework-8 (ZIF-8) followed by calcination. The synthesized nanoparticles were characterized as 20–30 nm spherical ZnO particles uniformly dotted with SnO2. When SnO2@ZnO were used as anode material for Zn/Ni batteries, the average specific capacity was approximately 600 mAh g− 1 and remained stable after 150 cycles at a rate of 1 C.
