Extended Data Fig. 4.: XPS spectrum of Al electrodeposits on carbon fibers, stainless steel and nickel foam.

From: Regulating electrodeposition morphology in high-capacity aluminium and zinc battery anodes using interfacial metal–substrate bonding

Extended Data Fig. 4.

XPS of Al deposited on (a)–(c) carbon fibers, (d)–(f) stainless steel, and (g)–(i) Ni foam. (a)(d)(g) C 1 s spectra; (b)(e)(h) O 1 s spectra; (c)(f)(i) Al 2p spectra. Upper panels and lower panels show spectra before and after Ar+ sputtering, respectively. After sputtering, the Al-O-C bonding was observed on samples where Al was deposited on carbon fibers. On other samples, no characteristic metal-substrate covalent bonding is observable.
