In this way, the electron transport as well as the diffusion of the lithium ions is facilitated [33]. X-Ray diffraction Lithium containing components like the cathodes after cycling in a

• to improve the power density and cyclability of LIBs [17][18]. Basically, such a strategy is based on the design of a nanostructured, metal current collector, by using Cu or Al nanorods to form a 3D conducting scaffold, to improve the kinetics of Li diffusion and electron transfer in the electrode
