Graphene fabrication via the electrochemical exfoliation route is promising due to the low-cost and straightforward process. Herein, we added a pretreatment of graphite sheet raw material using the immersion process in H2SO4/H2O2 mixture to pre-intercalate graphite before the exfoliation process. Pre-Treatment time in the constant H2SO4/H2O2 volume ratio was optimized to obtain the best electrical conductivity and charge transfer resistance. On the prepared samples, the optimum period is 3 minutes, which generates the electrical conductivity of 3298 S m-1. The smallest charge transfer resistance yielded is 55.90 Ohm. Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray (EDX) Spectroscopy were utilized for characterizing the morphology and elemental composition of samples.[/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]Charge transfer resistance,Electrical conductivity,electrochemical exfoliation,Electrochemical process,Elemental compositions,Energy dispersive x-ray,Lithium battery applications,Pre-Treatment[/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]charge transfer resistance,electrical conductivity,electrochemical exfoliation,graphene,pretreatment[/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]ACKNOWLEDGMENT This proceeding supported by USAID through Sustainable Higher Education Research Alliances (SHERA) Program.[/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/ICEVT48285.2019.8994001[/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]
