“…Besides, the cycling stability and capacity of Co 3 O 4 @NC@CNC material were superior to other materials mentioned in the literature. 5,6,10,17,27,40,47,54,55 The comparison is summarized in Table S1. The improvement of capacity and cycling stability should be attributed to the high carbon content, superior yolk−shell structure, and the synergistic effect of the nanoscale Co 3 O 4 @NC and CNC.…”

Despite the high theoretical capacity as the anode material of lithium-ion batteries (LIBs), Co 3 O 4 is subjected to rapid capacity decline and poor rate performance owing to its severe volume expansion and poor electronic conductivity. Herein, a yolk− shell structured Co 3 O 4 nanocomposite with double carbon shells (Co 3 O 4 @NC@CNC) was fabricated as an electrode material to improve the properties of LIBs. The Co 3 O 4 @ NC@CNC was derived from ZIF-67 within carbon nanocages (CNC) by carbonization. The hollow CNC acted as nanoreactors, which could effectively control the growth of ZIF-67 within the CNC and reduce the particle size of Co 3 O 4 @nitrogen-doped carbon (Co 3 O 4 @NC) nanocomposite derived from ZIF-67. When assessed as an LIBs anode material, the optimized Co 3 O 4 @NC@CNC material exhibited outstanding properties with high capacity, superior cycling stability, and rate performance (960 mAh g −1 at 0.5 A g −1 and 772 mAh g −1 at 2 A g −1 after 100 cycles). The electrochemical properties were ascribed to the yolk−shell structure and the synergistic effect of the nanoscale Co 3 O 4 @NC and CNC, which improved the electronic conductivity, alleviated the volume expansion effect, shortened the diffusion distance of Li + , and accelerated Li + transport kinetics. Moreover, the large specific surface and mesoporous structure were beneficial to the diffusion of electrolyte as well as capacitive contribution.

“…Thirdly, the encapsulation and confinement effect of GA effectively prevents the aggregation and shedding of metal oxides during the cycles, which is beneficial to the sufficient interaction between redox active sites and electrolyte and improves the lithium‐storage ability. The lithium‐storage properties of Co 3 O 4 ‐based electrodes reported previously are listed in Table . Overall, the specific capacity of 624 mAh g −1 (100 mA g −1 , 100 cycles) for our prepared Co 3 O 4 @GA is higher than those of Co 3 O4‐based materials at the same current density, including Co 3 O 4 /N−C, Co 3 O 4 /carbon, carbon fiber@Co 3 O 4 , CoO@Co 3 O 4 @C, and CF@Co–Co 3 O 4 /CNT.…”

The development of metal oxides as anodes of lithium‐ion batteries is severely limited because of their poor conductivity and serious volume expansion during the cycles. This work focuses on the improvement of electronic conductivity and cycle stability of metal oxides. The nanocubes of Prussian blue analogues are firstly encapsulated in the network of graphene aerogel (GA), and then the Co3O4@GA composites are synthesized after the subsequent calcination treatment. The resulting products are used as free‐standing and high‐performance anodes of LIBs, and the optimal electrode delivers a specific capacity of 624 mAh g−1 at 100 mA g−1 after 100 cycles together with a good cycle stability. The extraordinary lithium‐storage performances can be ascribed to the synergistic interaction between metal oxides and GA substrate. The incorporation of GA improves the electrode conductivity and alleviates the aggregation and volume expansion of metal oxide particles upon cycling, whereas cobalt oxides contribute a high specific capacity.

“…By contrast, the cycling performance of Carbon aerogel (CA)/Co 3 O 4 /Carbon (C) is higher than those of Co 3 O 4 nanocage/Co 3 O 4 nanoframework/TiO 2 [12], Co 3 O 4 nanocubes [13], Hollow Co-Co 3 O 4 /CNTs [14], Co 3 O 4 /nitrogen-doped carbon composite [15] and Co 3 O 4 nanocomposite [19]. But, it is admirable that Co 3 O 4 /nitrogen-doped carbon composite in reference [16], Co/Co 3 O 4 nanoparticles in reference [17] and porous Mn-Co 3 O 4 /C microspheresin reference [18] show super cyclability and rate capability. Nevertheless, the cycling stability and rate capability of Carbon aerogel (CA)/Co 3 O 4 /Carbon (C) composite anode are also superior to most of previous reports, indicating that the Carbon aerogel (CA)/Co 3 O 4 /Carbon (C) composite obtained in this study is a promising anode materials for LIBs.…”
