The Front Cover shows the cross-talk phenomena in high-voltage NCM523 graphite lithium ion battery cells, that is, the dissolution of transition metals (Mn, Co, Ni) from the NCM523 cathode and subsequent deposition at the graphite anode. These deposits induce alteration of the solid electrolyte interphase (SEI), significant SEI growth, and formation of Li metal dendrites.
