Fig. 4From: Environmental-Friendly and Facile Synthesis of Co3O4 Nanowires and Their Promising Application with Graphene in Lithium-Ion BatteriesThe TEM images of Co3O4NPs (a), CoNWs (b), and Co3O4NWs (c). The insets (a, b, and c) showed the selected area electron diffraction (SAED) patterns of the corresponding samples.
