Abstract

Article history: We prepare the transition structure of ZnCo O via transformation from two-dimensional (2D) 2 4 Received 11 June 2017 nanosheets to three-dimensional (3D) microspheres with the solvothermal method. ZnCo O nanocrys- 2 4 Received in revised form 5 August 2017 tallites were produced from the reaction of zinc acetate and cobalt nitrate in the non-aqueous methanol Accepted 7 August 2017 solution. The oriented attachment of ZnCo O nanocrystallites results in the formation of the 2D wrinkled- 2 4 Available online 9 August 2017 paper-like structure of ZnCo O . The 2D ZnCo O nanosheet agglomerate spontaneously because there 2 4 2 4 is no appropriate surfactant, and they have weak electrical double layers in the precursor solution. As the Keywords: stacking of 2D ZnCo O nanosheets increased, the aggregate of ZnCo O nanosheet was transformed into 2 4 2 4 Anode the 3D ZnCo O microspheres. The transition structure of the ZnCo O was composed of the intercon- 2 4 2 4 Lithium ion battery nected ZnCo O nanoparticles, which results in a porous structure to accommodate the volume expansion 2 4 Microsphere of ZnCo O structure during the charge process.
