摘要: Abstract ZnO/Ni/C composite hollow microspheres were synthesized by calcination of zinc–nickel citrate at 500 °C for 2 h in argon. The with an average diameter 1.2 μm are made up numerous nanoparticles sizes ranging from 15 to 25 nm. When applied as the anode materials lithium ion batteries, demonstrate excellent cycling stability. Compared ZnO solid microspheres, enhanced electrochemical properties composites attributed decoration nickel and carbon well its unique structures. ZnO/NiO/C prepared air also reveal good storage properties.
