In this paper, we reported an improvement of electrochemical performance from the LMNO by performing doping using Al and subsequent surface coating using Fe2O3. Synthesis of LNMO/Al was carried out via sol-gel method. The following surface coating of LNMO/Al was conducted by using co-precipitation process. The LNMO powder was characterized by X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM), and Electrochemical Impedance Spectroscopy (EIS). LiNi0.5Mn1.5O4 (LNMO) has been successfully synthesized, which confirmed by XRD and SEM characterization. Electrochemical performance of LiNi0.5Mn1.5O4 (LNMO) has been characterized using EIS, resulting in charge transfer resistance (Rct) value of 100 ohm.[/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]Al-doping,Charge transfer resistance,Co-precipitation process,Electric vehicle batteries,Electrical capacitance,Electrochemical performance,Fe2O3,LNMO[/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]Al-doping,co-precipitation,Fe2O3,LNMO,sol-gel method[/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][/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=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1109/ICEVT.2017.8323544[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
