NCA practically delivers high specific capacity (~200 mAh.g-1) with excellent electronic and ionic conductivity. Thanks to its extraordinary properties, NCA is projected to be used widely in the future generation of electric vehicles (EVs). However, its long synthesis process that engages high-Temperature heat treatment is one of the problems that hamper its industrial mass production. Herein, we develop a new synthesis method by involving microwave-assisted heat treatment to reduce synthesis time and thus improve energy efficiency. In this work, LiNi0.8Co0.15Al0.05O2 (NCA) was successfully synthesized by using a chemical coprecipitation method followed by microwave-Assisted heat treatment. The resulted materials were then characterized using X-Ray Diffraction (XRD) and Electrochemical Impedance Spectroscopy (EIS). It was revealed that 15 min of microwave heating was able to cut 50% of 12h total heat treatment time, marked with the successfully formed crystalline structure of NCA. Besides, NCA that was synthesized via microwave heating showed better electrochemical performance than NCA synthesized using a conventional method, indicated by a decrease of Rct in EIS measurement and an increase of specific capacity.[/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]Chemical coprecipitation method,Crystalline structure,Electric Vehicles (EVs),Electrochemical performance,Electronic and ionic conductivity,High specific capacity,High temperature heat treatment,Microwave assisted heating[/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 (LIB),microwave-Assisted heating,NCA[/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 was 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/ICEVT48285.2019.8993993[/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]
