TL;DR: In this article, the electrochemical reaction mechanism and recent progress including the synthetic method, various nanostructures and the strategies for improving performance of NiCo2O4 are summarized and discussed here.
Abstract: Lithium-ion batteries (LIBs) are deemed as the most promising energy storage devices due to their high power density, excellent safety performance and superior cyclability. However, traditional carbon-based anodes are incapable of satisfying the ever-growing demand for high energy density owing to their low intrinsic theoretical capacity. Therefore, the research of post-carbon anodes (such as transition metal) for LIBs has exponentially increased. Among them, NiCo2O4 together with its composites have been widely studied by academic workers due to their high theoretical capacity and excellent electronic conductivity. In this review, the electrochemical reaction mechanism and recent progress including the synthetic method, various nanostructures and the strategies for improving performance of NiCo2O4 are summarized and discussed here. Specially, the hollow porous nanostructured NiCo2O4-based materials composed of 2D structures usually exhibit excellent capacity and stable cyclability. This review also offers some rational understandings and new thinking of the relationship between the synthetic method, morphologies, blending, current collector and electrochemical performance of NiCo2O4-based anodes. We have reason to believe that the integration of NiCo2O4 materials in these clean energy devices provides important chances to address challenges driven by increasing world energy demand.

TL;DR: The authors demonstrate that amorphous mixed-valence vanadium oxide deposited on exfoliated carbon cloth (CC) can address the electrochemical instability and structural pulverization of vanadium oxides during charge/discharge cyclings, and suggest that tuning the V4+ /V5+ ratio ofVanadium oxide can efficiently suppress the dissolution of the active materials.
Abstract: Previous studies show that vanadium oxides suffer from severe capacity loss during cycling in the liquid electrolyte, which has hindered their applications in electrochemical energy storage. The electrochemical instability is mainly due to chemical dissolution and structural pulverization of vanadium oxides during charge/discharge cyclings. In this study the authors demonstrate that amorphous mixed-valence vanadium oxide deposited on exfoliated carbon cloth (CC) can address these two limitations simultaneously. The results suggest that tuning the V4+ /V5+ ratio of vanadium oxide can efficiently suppress the dissolution of the active materials. The oxygen-functionalized carbon shell on exfoliated CC can bind strongly with VO x via the formation of COV bonding, which retains the electrode integrity and suppresses the structural degradation of the oxide during charging/discharging. The uptake of structural water during charging and discharging processes also plays an important role in activating the electrode material. The amorphous mixed-valence vanadium oxide without any protective coating exhibits record-high cycling stability in the aqueous electrolyte with no capacitive decay in 100 000 cycles. This work provides new insights on stabilizing vanadium oxide, which is critical for the development of vanadium oxide based energy storage devices.
