Preparation and characterization of three dimensionally ordered macroporous Li5La3Ta2O12 by colloidal crystal templating for all-solid-state lithium-ion batteries Universiteit Hasselt
Three dimensionally ordered macroporous (3DOM) membranes of Li5La3Ta2O12 (LLTO) for all-solid-state lithium-ion batteries were prepared by using colloidal crystal templating of mono dispersed polystyrene (PS) spheres combined with sol–gel synthesis of LLTO precursor. During the sol–gel synthesis, the appropriate mixtures of CH3COOLi, La(NO3)3·6H2O and Ta(OC2H5)5 were dissolved in two different solvents to prepare garnet-type LLTO. Various sizes ...
