“…For both kinds of NiO film, there are two anodic peaks located at about 1.75 V and 2.30 V in the first scan, which can be assigned to the decomposition of SEI and the reaction between Ni and Li 2 O, respectively [21]. Compared to planar-NiO, however, foam-NiO exhibits a stronger peak at 1.75 V. A possible explanation for this difference is the catalytic decomposition of Li 2 O on foam nickel substrates during charging, because a similar phenomenon was also observed in Ni-coated ZnO [22].…”

NiO films for lithium-ion batteries were deposited on copper plates and foam nickel substrates by electrodeposition and subsequent heat treatment at 300°C. At a discharge/charge rate of 0.1 C, foam NiO films delivered reversible capacity larger than 650 mAh g -1 and capacity retention over 93% after 50 cycles. NiO films deposited on foam nickel exhibited higher reversible capacity, better cyclability, as well as higher rate capability than those on copper plates. The unique three-dimensionally porous morphologies of foam NiO films were responsible for the better electrochemical performance, which provided not only high electrode/electrolyte contact area but also a good electronic conduction matrix. The present finding offers a new pathway for the large scale fabrication of highenergy-density electrodes for lithium-ion batteries.

“…During the second cycle, a peak at 0.8 V is associated with reaction of NiO and Li + ions [16]. Redox peaks at 1.6 and 2.2 V for both the C/NiO and CNS/NiO are related to the conversion reaction between NiO and lithium [27]. For NiO/C electrode, the intensity of peaks at 1.6 and 2.2 V decreases for the second and the fifth cycles which may be attributed to the poor conversion of NiO and lithium.…”

Carbon nanostructures (CNS) with high electrical conductivity and unique branched structure of carbon nanotubes combined with NiO nanofibers (NFs) were used as anode for lithium-ion batteries. CNS works as a framework substrate for the anodic conversion reaction of nickel oxide (NiO). Electrochemical performance and behavior of CNS/ NiO anodes is compared with the conventional carbon (C)/ NiO anodes. CNS/NiO NF-based anode retains high specific capacity under different current densities compared to C/NiO anode. Moreover, specific capacity as high as 450 mAh/g for CNS/NiO NF anode is observed compared to only 90 mAh/g for C/NiO NFs using a current density of 500 mA/g after 500 cycles. This improved performance is attributed to the highly conductive network of CNS leading to efficient charge transfer. The high porosity, electrical conductivity as well as the branched and networked nature of CNS reveal to be of critical importance to allow the electrochemical conversion reactions.

“…However, it often suffers the loss of capacity upon the cycling due to drastic volume changes during the formation of lithium zinc alloys [6][7][8]. Therefore, a lot of effort has been devoted to overcome these problems; correspondingly, many methods have been developed, such as (i) preparing ordered nanostructured materials [2,9]; (ii) incorporating with Ni 3 ZnC 0.7 [10]; (iii) coating with Ni, C, and CoO-C layers [6,11,12]; and (iv) doping with Mg [13]. These techniques enhance the conductivity, facilitate the lithiation/delithiation process, or buffer the volume changes.…”

Porous Zn 1 − x Mn x O (x = 0.1, 0.2, 0.44) nanosheets were prepared by a low-cost, large-scale production and simple approach, and the applications of these nanosheets as an anode material for Li-ion batteries (LIBs) were explored. Electrochemical measurements showed that the porous Zn 0.8 Mn 0.2 O nanosheets still delivered a stable reversible capacity of 210 mA h g −1 at a current rate of 120 mA g −1 up to 300 cycles. These results suggest that the facile synthetic method of producing porous Zn 0.8 Mn 0.2 O nanostructure can realize a better cycle durability with stable reversible capacity.
