The samples were prepared using LiOH·H2O, FeSO4·7H 2O, H3PO4, and citric acid which are dissolved in ethylene glycol and water mixture solvent with various concentration of LiOH from 0.3 to 1.8 M while the Li:Fe:P molar ratio was fixed at 3:1:1. The precursors were heated in an autoclave at fixed temperature of 180°C for 8 hours. The prepared samples were characterized using an X-Ray Diffraction and Scanning Electron Microscopy to study the crystal structures and morphology of the prepared particles, respectively. It was found that LiFePO4 structures were observed at all various concentrations. However, a small part of crystal structure impurity was detected for the samples that fabricated at concentration 0.3 M and some coagulated part of sample from 1.5 M and 1.8 M. We found that the optimum precursor concentration for the present method and preparation condition was at 1.2 M of LiOH precursor. © 2013 IEEE.[/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,LiFePO,Lithium iron phosphates,Lithium-ion battery,Precursor concentration,Preparation conditions,Solvothermal,Solvothermal 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=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Cathode material,Lithium ion battery,Solvothermal[/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/rICT-ICeVT.2013.6741526[/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]
