James R. Wilson, J. Scott Cronin, Scott A. Barnett, and Stephen J. Harris, “Measurement of 3-dimensional microstructure in a LiCoO2 positive electrode” LiCoO2 Particle #1…
The use of high resolution X-ray CT has provided here the first quantitative microstructural, 3D reconstruction of a Li ion battery electrode. Several geometrical parameters…
The swelling and shrinking associated with insertion and de-insertion of lithium into battery electrodes on each cycle can cause battery fracture, degradation, and failure. Lithium…
Research on lithium batteries has shown that plating (deposition) of metallic Li is an important battery degradation and failure mechanism and a safety concern of…
We describe the first direct in-situ, operando measurements of Li transport in an operating cell. The architecture of the experiment, useful in viewing battery failure in-situ, is…
Many properties of potential new cathode materials for Li ion batteries can be predicted or estimated prior to synthesis via the use of ab initio calculations based…
