An entire active region of an anode-supported solid oxide fuel cell was structurally analyzed by X-ray computed nano-tomography using full-field transmission X-ray microscopy (NANO-TXM). A total three-dimensional volume of ∼38,500 μm 3 was imaged,

The three-dimensional (3D) morphologies of two types of lithium-ion battery cathodes, LiCoO_2 (LCO) and LiCoO_2/Li (Ni_(1/3)Mn_(1/3)Co_(1/3))O_2 (LCO/NMC) composites, have been measured using focused ion beam scanning electron microscopy (FIB-SEM) an

An accurate 3D morphological analysis is critically needed to study the process–structure-property relationship in many application fields such as battery electrodes, fuel cells and porous materials for sensing and actuating. Here we present the ap

Electrostatic spray deposition (ESD) was used to deposit La0.6Sr0.4Co0.2Fe0.8O3-δ (LSCF) cathode films on dense Ce0.9Gd0.1O2−δ (CGO) electrolytes. LSCF films with different morphologies were obtained by varying the substrate temperature (250 to 4

In this work we elucidate the 3D microstructure of the LiCoO2 phase in a fresh commercial Li-ion battery positive electrode using a focused ion beam-scanning electron microscope. The particles have a highly irregular shape that includes significant i

Coarsening of the nickel phase is known to occur in solid oxide fuel cell (SOFC) anodes consisting of Ni and yttria-stabilized zirconia (YSZ). However, the exact nature of the coarsening process is not known, nor how it affects three-phase boundaries

Composite La0.8Sr0.2MnO3 (LSM)–Y2O3-stabilized ZrO2 (YSZ) cathodes with compositions ranging from 30:70 to 70:30 wt.% LSM:YSZ were studied both electrochemically and microstructurally. Polarization resistance was lowest for the 50 wt.% YSZ composit
