Semi-hollow/Solid ZnMn2O4Microspheres: Synthesis and Performance in Li Ion Battery
摘要
Abstract
Porous semi-hollow/solid ZnMn2O4microspheres were controllably synthesized via template and sol-vothermal methods respectively. The as-synthesized samples were characterized by X-ray diffraction (XRD), scan-ning electron microscope (SEM) and transmission electron microscope (TEM). It is found that the solvent ratio ex-erts a crucial effect on the morphology and microstructure of solid ZnMn2O4microspheres. The porous solid ZnMn2O4microspheres could be obtained when the volume ratio of ethylene glycol to deionized water was 3 : 1. The semi-hollow ZnMn2O4microspheres with a double-layer ZnMn2O4shell and a small C core could be synthe-sized via a template-solvothermal method and post-calcination process. The electrochemical properties of as-prepared semi-hollow/solid ZnMn2O4microspheres as anode materials of lithium-ion batteries were investigated. Semi-hollow ZnMn2O4microspheres exhibit higher initial discharge capacity, better rate capacity and cycling per-formance than solid ZnMn2O4microspheres.关键词
