Using portable electronic devices, especially mobile phones and notebook computers, has been increasing, and leading to a strong need of their power-sources. However, secondary batteries using a liquid electrolyte have weaknesses, such as prone to leakage and difficulty of packing. Solid polymer electrolyte is a solution to the existing problems. The objective of this research is to prepare an environmentalfriendly and cheap material as the solid polymer electrolyte. In the present study, the effect of succinyl group on to polymer electrolyte membrane which synthesized from chitosan and lithium perchlorate salts was investigated. The N-succinyl chitosan was obtained by reacting chitosan with succinic anhydride. Solid polymer electrolyte membranes were derived from N-succinyl chitosan with different ratios of lithium perchlorate. The degree of deacetylation of chitosan was determined by FTIR analysis. The degree of deacetylation and molecular mass (Mv) of chitosan were 79.26% and 691,053 g/mol, respectively. Synthesis of N-succinyl chitosan has been successfully carried out, which is indicated by the characteristic peaks at wavenumbers of 1640 cm-1 and 1560 cm-1 correspond to-C=O stretching and-NH bending of succinyl groups on FTIR spectrum of Nsuccinyl chitosan. Modification of chitosan by the addition of succinyl group increases the membrane ionic conductivity values. Chitosan membrane conductivity is 2.88×10-6 S.cm-1, while the conductivity after adding succinyl groups was increased to 3.93×10-4 S.cm-1. A N-succinyl chitosan membrane contained 10% (w/w) lithium perchlorate showed conductivity of 8.01×10-3 S.cm-1. This solid polymer electrolyte membrane was suggested to have one potential used for polymer electrolyte in lithium battery applications. © (2014) Trans Tech Publications, Switzerland.[/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]Lithium battery applications,Lithium perchlorate,Polymer electrolyte,Polymer electrolyte membranes,Portable electronic devices,Solid polymer electrolyte membranes,Solid polymer electrolytes,Synthesis and characterizations[/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]Chitosan,Lithium perchlorate,N-succinyl chitosan,Polymer electrolyte[/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/10.4028/www.scientific.net/AMR.896.58[/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]
