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.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Cath-ode materials,Electrochemical performance,FT-IR spectrum,Hexagonal layered structure,Micro-sized particles,Solid state reaction method,Synthesis route,Voltage ranges[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Electrochemical performance,Li-ion batteries,NCA,Synthesis[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]Author Contributions: Conceptualization, H.W., F.I., and W.S.; Data curation, C.S.Y.; Formal analysis, C.S.Y.; Investigation, S.U.M., H.W., F.I., and W.S.; Methodology, C.S.Y.; Project administration, A.P.; Supervision, A.P.; VFaulinddaitniogn:, HT.hWis., Fr.eI.s,eaanrdchW .wS.a; sVisfuuanldizeadti obny, S.tUh.eM .M; Winriistitnryg—oofrigRiensaeladrrcahf,t, CTe.Sc.hYn.;oWlorgityinga—ndre vHieiwgh&ere dEitdinugc,aAtio.Pn.
