3DOM Structure for Battery Electrodes and Electrolytes
The performance of lithium-ion batteries, especially at high rates, critically depends on the morphology of the battery active materials and the microstructure of the electrode. In particular, in all-solid-state batteries, the structure is critical because of the poor contact of the solid active material with the solid electrolyte. A three-dimensionally ordered macroporous (3DOM) structure is an ideal structure due to its high porosity and regularity, which provide a large contact area between the electrode and electrolyte and a uniform current distribution, respectively. The 3DOM solid electrolyte-active material composite electrode clearly exhibits a charge and discharge behavior, indicating that the 3DOM solid electrolyte-active material composite electrode can be applied to all-solid-state batteries.
