“…Figure 1 shows the FTIR spectra of precursors from each process, namely NCA-PCP and NCA-PSS. The absorbance spectra of NCA-PCP and NCA-PSS samples show similar results to those of studies by Agarwal et al on Ni nanoplates [26], Motlagh et al on Ni(OH)/NiO nanoparticles [27], and Seo et al on Li(Ni0.8Co0.16Al0.04)O2 materials [15]. The sharp peak around the value of 3600/cm and the broad peak around the value 3400/cm indicate a stretching mode of the disturbed hydroxide group and stretching vibration of the free hydroxide group, which correspond strongly to the presence of metal hydroxide species (Ni(OH)2).…”

Nickel-rich cathode material, NCA (85:14:1), is successfully synthesized using two different, simple and economical batch methods, i.e., hydroxide co-precipitation (NCA-CP) and the hydroxides solid state reaction method (NCA-SS), followed by heat treatments. Based on the FTIR spectra, all precursor samples exhibit two functional groups of hydroxide and carbonate. The XRD patterns of NCA-CP and NCA-SS show a hexagonal layered structure (space group: R_3m), with no impurities detected. Based on the SEM images, the micro-sized particles exhibit a sphere-like shape with aggregates. The electrochemical performances of the samples were tested in a 18650-type full-cell battery using artificial graphite as the counter anode at the voltage range of 2.7–4.25 V. All samples have similar characteristics and electrochemical performances that are comparable to the commercial NCA battery, despite going through different synthesis routes. In conclusion, the overall results are considered good and have the potential to be adapted for commercialization.

Bacterial cellulose (BC) hydrogel was used as a three‐dimensional scaffold for the hierarchical formation of nickel oxyhydroxide (NiOOH). The formation was completed, without the need of any external energy utilization, special apparatus, and surface modification at room temperature. A solution‐process method is utilized through controlled reaction conditions. The proposed mechanism ascribed that the abundant water channels in the BC hydrogel play a pivotal role in the formation of hierarchical NiOOH nanocoating on individual fiber while preserving the open three‐dimensional structures of BC. The composite structures in both hydrogel and freeze‐dried forms were compared using optical microscopy, scanning electron microscopy, and powder X‐ray diffractions. Furthermore, the formation mechanism was explained on the basis of spectroscopy analysis. As a final step, the formed aerogels (BC‐NiOOH) were annealed at 300°C for a particular time to transform NiOOH to hierarchical nickel oxide (NiO) on the surface of BC without any structural deformation.
