DOIAbstract
The relationship between the structure and crystallinity of lithium titanate Li4Ti5O12, at different synthesis post-treatment conditions on the electric energy storage capacity is discussed. Li4Ti5O12 was synthesized by solid-state reaction at a high temperature and time (950 °C, 24 h) and the resulting material was post-treated with a ball milling process at different times. Additional samples were prepared with a post-calcination after and adding graphite carbon previously to the longer applied ball-milling time. All the obtained materials were structurally and morphologically characterized by XRD and SEM techniques. To study the effect of ball milling time on the lithium-ion storage capacity, electrochemical experiments of galvanostatic ...
