Abstract:
A quantitative nondestructive Bragg-edge imaging technique for power-storage degradation was developed using commercial prismatic-shaped lithium-ion battery cells. The C or Li atoms/ions column density [cm −2 ] images for five phases of the negative electrode material (graphite, Li 0.04 C 6 , Li 0.2 C 6 , Li 0.5 C 6 , and Li 1.0 C 6 ) with a 1 mm spatial resolution were obtained by considering the crystalline orientation for both fresh and fatigue cells. In the fresh cell, most of the graphite was uniformly converted to Li 1.0 C 6 by charging, and in the fatigue cell, the graphite changed to various phases (especially, Li 1.0 C 6 and Li 0.5 C 6 ) by charging, and their spatial distributions were nonuniform.
