“…In fact, a gradual increase of the specific capacitance can be observed from Figure e, which can be explained by the formation of “nanocrystal” transition metals from conversion reaction that act as catalysts to facilitate the reversible formation of the SEI layer(a.k.a. surface passivation layer) and/or the kinetically driven polymeric gel‐like films especially on the hierarchically designed electrode materials . Among all the factors including phase and/or morphology transition in the electrode and corresponding charges in electrode/electrolyte interface property that leads to such cycling behavior, we believe this behavior is similar to the stability behaviors of other nanoparticle composite‐based electrodes presented in other references .…”

Metal oxide based anodes for lithium ion batteries should theoretically exhibit high specific capacities, but their disappointing experimentally measured capacities and cycle stabilities inhibit their usages in the commercial and industrial level. Here, we propose a simple method to process the MnO 2 / 2,2,3,3,4,4,4-Heptafluorobutylamine-functionalized-grapheneoxide(HFBA-fGO) composite anode, in which HFBA-fGO is composited with the MnO 2 based anode to simultaneously enhance the specific capacity to reach the theoretical capacity of MnO 2 and improve the cyclic stability significantly. In fact, the MnO 2 /HFBA-fGO composite anode exhibits high performance with specific capacity of 1030 mAhg À1 under 100 mAg À1 and stable cyclic performance at least up to 200 cycles of repeated charging and discharging even at a high rate of 1 A g À1 . A detailed analysis of the enhanced cyclic stability of the composite anode is performed through the investigation of the electrode-electrolyte interfaces using the electrochemical impedance spectroscopy and cyclic voltammetry. Such results were possible because of the significantly suppressed irreversible formation of the surface passivation layer caused by the fluorine-rich terminal groups of the HFBA-fGO, which leads to enhanced cyclic stability. We believe that this method should be effective even for other various metal-oxide anodes besides MnO 2 as well, which certainly broadens the potential use of HFBA-fGO.

“…The phenomenon of gradually increasing reversible capacity upon cycling may be caused by the reversible generation of a polymeric gel-like film evolving from kinetic activation during the charge/discharge process [45]. The electrochemical impedance spectroscopy (EIS) investigations were conducted at different cycles (10th, 30th, and 50th at 50 mA g −1 ) in the frequency in the range of 100 kHz and 10 MHz for the sake of illuminating charge transfer and Li + diffusion kinetics.…”

In this study, uniform Co 3 O 4 nanoparticles are prepared via a simple and facile hydrothermal synthesis without calcination treatment. When the Co 3 O 4 nanomaterials are investigated as anodes for lithium ion batteries, a good electrochemical property is achieved. Particularly, the reversible capacity of the as-synthesized Co 3 O 4 nanoparticle has a significant growth from 383 mAh g −1 of the initial cycle to 471 mAh g −1 of the 300th cycle at 2 A g −1 . Moreover, when it recovers to 50 mA g −1 after different current densities, a superior reversible capacity of 695 mAh g −1 can be reached. Such favorable electrochemical properties will make the as-obtained Co 3 O 4 have a good application prospect as anode material for lithium ion batteries.

Porous hollow Co3O4 microspheres wrapped with graphene oxide were synthesized by a step solvothermal method and subsequent heat treatment. Benefiting from the design of special porous hollow microspheres, the effective specific surface area was greatly increased, the sufficient contact between the porous hollow Co3O4 microspheres and electrolyte was achieved, and then a charge specific capacity of 888.59 mA h g–1 was gained. Meanwhile, partial stress from the charging/discharging process was greatly relieved due to the abundant pores and hollow structure, excellent cycling stability was realized, and the charge specific capacity of the 1000th cycle was 465.75 mA h g–1 at 5 C (1 C = 890 mA g–1). In addition, the conductivity of Co3O4 microspheres was effectively improved due to the tight package of graphene oxide to Co3O4 microspheres, and superior rate performance was attained (280.99 mA h g–1 at 10 C).
