As a result, the cu foil with carbon layer achieves a ce of ~99% (1 ma·cm 2 , 1 mah·cm 2 ) for more than 150 cycles. furthermore, they also reported a spectrum of 2d atomic crystals as the. Download scientific diagram | i) schematic illustration of the li deposition on bare cu foil, ni foam, and 3d graphene@ni foam. a,d) a great number of large li dendrites protruding upward appear.
Obviously, at the current density of 1.0 ma cm −2 and the capacity of 1.0 mah cm −2 , the li ni li 3 n ns@cc symmetrical battery displays stable and ultralong cycling for 2000 h with an. According to the binary diagrams of these 10 metals with li , metallic cu, cr, ti, and ni are insoluble for li metals, while au, al, bi, pd, in, and ag metallic substrates are soluble for li metal, which suggests that the solid diffusion of li in the former four metals might be more difficult than that in the latter six metals. The li deposition behaviors on bare cu foil (b cu) and nmmf@c modified cu foil (nmmf@c cu) were investigated using the fesem technique. figure 3a shows a top view of the li film that is electrodeposited on the nmmf@c cu with a plating capacity of 0.5 mah cm −2 at the current density of 0.5 ma cm −2. Schematic illustration of li plating on different substrates with different capacities: (a) a d: sporadic lithium nucleation on bare ni foam; a’–d’: uniform deposition on nio nf substrate. (b) voltage profiles of the li plating on the bare ni foam and the nio nf at a current density of 1.0 ma cm −2 and a li plating capacity of 4 ma h cm.

As depicted in figure s4 (supporting information), all the integrated cuo@cu nanowire arrays deliver higher surface resistances than bare cu substrate, rendering a vertical conductivity gradient that is beneficial to the bottom up li deposition. in the following part, m cuo@cu is used as the main example to describe the characterizations. The li deposition behaviors on bare cu foil (b cu) and nmmf@c modified cu foil (nmmf@c cu) were investigated using the fesem technique. figure 3a shows a top view of the li film that is electrodeposited on the nmmf@c cu with a plating capacity of 0.5 mah cm −2 at the current density of 0.5 ma cm −2. compared with uncontrolled growth of li.
