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…
