摘要：

Li4Ti5O12 spinet is a popular zero-strain negative insertion material capable of acting as a host for both Li+ and Na+ ions. For efficient electrochemical activity, it is key to produce Li4Ti5O12 spinet in nanoscale morphology with reduced diffusion barrier. Here, we report (ultrasonic) sonochemical synthesis as a novel energy-miser route to achieve spherical 100-150 nm spinel particles with restricted annealing for just 2 h. Synchrotron diffraction analysis reveals the formation of phase-pure spinet product. The resulting Li4Ti5O12 yields desirable (de)intercalation of u(+) (at 1.55 V) and Na+ (at 0.9 V) ions with excellent electrochemical properties. (C) 2016 Elsevier Ltd. All rights reserved.
