Cross-nanoflower CoS2 in-situ self-assembled on rGO sheet as advanced anode for lithium/sodium ion battery

Cross-nanoflower CoS2 on rGO nanosheets has been synthesized by simply controlling the pre-reaction step during hydrothermal route. Three-dimensional CoS2 cross-nanoflowers of 150–200 nm in diameter are formed in-situ through self-assembling with rGO nanosheets reduced from GO (shorten as CoS2–NF/rG...
