Here, polyethylene oxide (PEO), polyvinyl alcohol (PVA), and lithium hydroxide (LiOH) SPEs were prepared by an ultrasonic method to improve the ionic conductivity and shorten the synthesis time. This procedure has successfully yielded a flexible, transparent, and homogeneous SPEs, which were thermally stable at fairly high temperature as revealed from thermogravimetric analysis (TGA). These samples also showed relatively high ionic conductivity at room temperature with the highest conductivity of 1.25 × 10−4 S/cm and low activation energy of 0.253 eV demonstrated by sample with 2 wt% LiOH loading. Moreover, this sample was also stable in the measured voltage range, i.e., -5 to 5 V. DFT calculation showed that strong intermolecular charge transfer was present in the interaction between Li+ ion with PVA and PEO chain.[/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]Intermolecular charge transfer,Lithium hydroxide,Low-activation energy,Poly (vinyl alcohol) (PVA),Polyethylene oxide (PEO),Solid polymer electrolytes,Solution cast methods,Ultrasonic methods[/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]Lithium hydroxide (LiOH),Polyethylene oxide (PEO),Polyvinyl alcohol (PVA),Solid polymer electrolytes (SPEs),Ultrasonication[/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][{‘$’: ‘This work was supported by the Institute for Research and Community Services (LPPM) Institut Teknologi Bandung through Riset KK, 2020 ITB Research Program (1R/I1.C01/PL/2020) and the Sustainable Higher Education Research Alliances (SHERA) program, USAID.
