Although the electrochemical properties of porous LiMn 2 O 4  microspheres are usually improved compared to those of irregular LiMn 2 O 4  particles, the effects of the different synthesis conditions on the preparation of the porous LiMn 2 O 4  microspheres are rarely discussed in detail. In the present work, porous LiMn 2 O 4  microspheres were successfully synthesized by using molten LiOH and porous Mn 2 O 3  spheres as a template. Multiple factors were considered in the preparation process, including reagent concentration, pH, adding mode, heating time, etc. The morphology of the MnCO 3  template was crucial for the preparation of porous LiMn 2 O 4  microspheres and it was mainly affected by the concentration of reactants and the pH value of the solution during the precipitation process. During the lithiation of Mn 2 O 3  microspheres, the heating temperature and the ratio between Mn 2 O 3  and lithium salt were the most significant variables in terms of control over the morphology and purity of the LiMn 2 O 4  microspheres. Furthermore, we demonstrated that the porous LiMn 2 O 4  microspheres presented better rate capability and cyclability compared to commercial LiMn 2 O 4  powder as cathode materials for lithium-ion batteries (LIBs). This study not only highlights the shape-controllable synthesis of LiMn 2 O 4  microspheres as promising cathode materials, but also provides some useful guidance for the synthesis of porous LiMn 2 O 4  microspheres and other LIB' electrode materials.
