Graphene aerogel encapsulated Fe-Co oxide nanocubes derived from Prussian blue analogue as integrated anode with enhanced Li-ion storage properties

Coordinating gallium hexacyanocobaltate: Prussian blue-based nanomaterial for Li-ion storage

“…17,18 In particular, Prussian blue analogs (PBAs), which are typical MOFs, are considered one of the most attractive candidates because of their easy of synthesis in aqueous solution at room temperature without the need of additives or post-processing. 19 Recently, the study of PBAs as cathode materials for LIBs has mainly focused on functionalized PBAs (for example, those treated by etching, oxidation, or combination with other materials such as carbon nanotubes), 20,21 which results in highly improved electrochemical properties. However, this extra processing increases the fabrication costs during a massive fabrication.…”

Graphene Aerogel Modified Carbon Paper as Anode for Lithium‐Ion Batteries

“…Regarding the electrochemical characteristics of the electrodes, it can be seen in Figure a, a broad irreversible reduction peak close to 0.2 V during the first lithiation, attributed to the formation of the well‐known solid electrolyte interphase (SEI) film on the surface of the anode . This peak is clearly shifted to 0.54 V in the subsequent two cycles due to the polarization of the electrode . The intensity decrease of the reduction peak after the first cycle is strongly correlated with the decrease of the capacity while it remains almost unchanged during the second and third cycle, implying a good electrochemical reversibility and stability of the electrode .…”

Synthesis, characterization and magnetic properties of Ni, Co and FeCo nanoparticles on reduced graphene oxide for removal of Cr(VI)

“…The electrode has been shown to have a high reversible capacity [7]. The other promising application of graphene-based compounds is graphene aerosol decorated with iron cobalt oxide nanoparticles in Li-ion batteries [8]. Composite graphene material has been shown to be useful as anode material for lithium ion batteries, where the nanoparticles prevent graphene sheet restacking.…”
