Abstract
Abstract Monodispersed spherical Li1.3Al0.3Ti1.7(PO4)3 (LATP) precursor particles are prepared by hydrolysis-complexation combined with spray-drying processes, and the desirable targeted LATP-900 particles are obtained after being calcinated at 900 °C in air confirmed by thermogravimetry-differential scanning calorimetry and X-ray diffraction analyses. The high compacted density of the particles with normal size distribution can be conductive to collecting the compacted LATP pellets, which can reach as high as 1.608 × 10−4 S cm−1 of ionic conductivity at 30 °C. The assembled LiCoO2/LATP-900/Li cell can stably deliver 138.2 mAh g−1 of discharge specific capacity after only four cycles and quickly recover to 132.3 mAh g−1 after 80 cycles when the current is set back to 0.1 C with nearly 100% coulombic efficiency, which suggests that the LATP-900 pellet can become a promising candidate for the high performance solid lithium ion batteries.
