Abstract

Graphical abstract: Highlights: Size-controllable porous NiO electrodes were prepared by a simple thermal oxidation route. The prepared porous NiO electrodes exhibit high capacity and excellent rate capability and cycling stability. The smaller nanopore and crystallite size are benefical to improve the electrochemical properties of the porous NiO electrodes. Abstract: Size-controllable porous NiO electrodes were prepared by a simple and easily scalable thermal oxidation route and were evaluated as anode materials for lithium ion batteries. The nanopore size of the prepared electrodes can be obtained in the range from 20 to 80 nm by varying the thermal oxidation condition. Lithium storage performance measurement showed that porous NiO electrodes exhibit high capacity and excellent rate capability and cycling stability. Furthermore, it was shown that the smaller nanopore and crystallite size are beneficial to improve the electrochemical properties of the porous NiO electrodes.
