Abstract
Abstract Spherical and nanostructured Li4Ti5O12 powders were successfully prepared through spray-drying method. Li4Ti5O12 began to be formed after calcining the spray-dried amorphous precursor at approximately 350 °C, and a single phase was obtained at 750 °C. Spherical and porous Li4Ti5O12 particles consisting of polyhedral particles assembled from 21–45 nm grains and 4–24 nm pores. An about 1 nm-thick amorphous layer can also be observed on the surface of the nano-sized grains. The Li4Ti5O12 prepared at 750 °C exhibits the initial discharge capacities of 218 and 211 mAh g−1 and a high retention of 99.90 % and 99.67 % for 50 times at a rate of 1 C or 2 C in the voltage range of 1.0–2.5 V, respectively.
期刊介绍：
The Journal of advanced oxidation technologies (AOTs) has been providing an international forum that accepts papers describing basic research and practical applications of these technologies. The Journal has been publishing articles in the form of critical reviews and research papers focused on the science and engineering of AOTs for water, air and soil treatment. Due to the enormous progress in the applications of various chemical and bio-oxidation and reduction processes, the scope of the Journal is now expanded to include submission in these areas so that high quality submission from industry would also be considered for publication. Specifically, the Journal is soliciting submission in the following areas (alphabetical order): -Advanced Oxidation Nanotechnologies -Bio-Oxidation and Reduction Processes -Catalytic Oxidation -Chemical Oxidation and Reduction Processes -Electrochemical Oxidation -Electrohydraulic Discharge, Cavitation & Sonolysis -Electron Beam & Gamma Irradiation -New Photocatalytic Materials and processes -Non-Thermal Plasma -Ozone-based AOTs -Photochemical Degradation Processes -Sub- and Supercritical Water Oxidation -TiO2 Photocatalytic Redox Processes -UV- and Solar Light-based AOTs -Water-Energy (and Food) Nexus of AOTs
