Figure 5

(a,b) Field emission scanning electron microscopic (FESEM) images of the recharged P-HSC deposited onto CP cathode after the 1st and 20th cycle. White scale bars, 1 μm. Green scale bars, 200 nm. (c,d) FESEM images of the recharged SP cathode after the 1st and 20th cycle. White scale bars, 1 μm. Green scale bars, 400 nm. Insets of a–d show the corresponding enlarged FESEM images. The current density is 300 mA g−1 and the specific capacity is 3,000 mAh g−1. (e,f) Corresponding FTIR spectra of two kinds of recharged cathode after the 1st and 20th cycle.
