From: Mesoporous hexagonal Co3O4 for high performance lithium ion batteries
Ex-situ TEM images and SAED patterns of Co3O4 electrodes taken from the fully discharged (a–c) and fully charged (d–f) states in the first cycle and after 100 cycles (g–i).
(a), (d) and (g) show individual mesoporous crystals at different states of the reduction and oxidation processes. (b), (e) and (h) are the corresponding SAED patterns. (c), (f) and (i) are the lattice resolved TEM images at various states of the reduction and oxidation processes.
