“…The peak at 0.95V could be attributed to the conversion of NiO to Ni, and the peak at 0.55V should be resulted from the formation of SEI films. In the first oxidation process, two peaks were recorded at 1.40V and 2.19V, which correspond to the dissolution of the organic SEI film [47], and the charge reaction Ni + Li2O → NiO + 2Li, respectively [5]. The CV curves in the subsequent two cycles almost overlap, which matches well with the result of previous discharge/charge voltage profiles, indicating excellent stable cycle reversibility of the work electrode.…”

“…It retains 70.5% of initial capacity, much higher than pure NiO electrode of only 55.7%. Apparently, the NiO/CNTs electrode shows superior rate performance than NiO sample, and also better than the reported results in the literatures [3,5,48,49]. In addition, the specific capacity increase at low rate (0.1C,0.2C and 0.5C) and decrease at high rate (1C, 2C and 5C).…”

“…Up to now, it has been widely demonstrated that these obstacles could be partly solved by building porous nanostructure because the porosity could not only alleviate the strain of volume change to keep the stability of metal oxide electrode, but also shorten the transport distance of electrons and ions to improve the rate performance during cycles [3][4][5][6][7]. Unfortunately, due to its high surface area, thick and wide range of solid electrolyte interphase (SEI) films on the electrode surface would form during cycles, which can consume some Li + supplied by the cathode, leading to a low columbic efficiency and a high level irreversibility loss of capacities.…”

A conversion‐type, NiO–MCMB (mesocarbon microbeads) composite anode prepared by high‐energy ball milling is here characterized and tested in lithium half and full cells. An optimized and submicrometric morphology allows the NiO–MCMB electrode to achieve high cell performance and excellent rate capability, that is, delivering specific capacities of 515 and 450 mAh g−1 when cycled at current densities as high as 545 and 1090 mA g−1, respectively. The NiO–MCMB composite anode is studied in a full lithium‐ion battery using a high‐voltage LiNi0.5Mn1.5O4 electrode that is considered a suitable cathode in combination with conversion‐type electrodes. The battery delivers a specific capacity of 90 mAh g−1 with high coulombic efficiency and an average working voltage of 4.1 V. The electrochemical results suggest the viability of the alternative cell configuration here adopted for the development of low‐cost, high‐energy‐density lithium‐ion batteries.

“…The first discharge curve of FGS shows that FGS has a voltage plateau at about 0.84 V. Furthermore, the first discharge curve of NiO indicates that NiO has a voltage plateau at about 0.64 V. For FGS/NiO, in the first discharge, there is a quick potential drop to about 0.84 V at first, followed by a long voltage plateau between 0.84 and 0.6 V. This voltage plateau is from two kinds of reactions. One is from the convention reaction of NiO [14]: NiO + 2Li↔Ni + Li 2 O. The other is from the reaction of FGS with Li.…”

Graphene is an excellent substrate to load nanomaterials for energy applications due to its large surface area, excellent conductivity, mechanical strength, and chemical stability. In this study, thermal exfoliated functionalized graphene sheets with good conductivity and high BET surface area are anchored with mesoporous NiO nanoplates by in situ chemical synthesis approach. Electrochemical characterization shows that functionalized graphene sheets-NiO sample exhibits a high capacity of about 700 mAh/g at a discharge current density of 100 mA/g and a good cycling ability. The high capacity and good cycling ability of functionalized graphene sheets -NiO material were attributed to the intimate interaction between the graphene sheets and NiO nanoplates. The graphene sheets not only enhance the conductivity of NiO nanoplates but also improve the structure stability of NiO nanoplates. Furthermore, the mesoporous structure of NiO nanoplates is available to the transfer of electrolyte. Such functionalized graphene sheets-NiO nanocomposite could be a promising candidate material for a high-capacity, low cost, and nontoxic anode for lithium-ion batteries.
