Synthesis and Characterization of Solid Polymer Electrolyte from N-Succinyl Chitosan and Lithium Perchlorate (original) (raw)

2014, Advanced Materials Research

Batteries are being developed to solve the global energy crisis. 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 environmental-friendly 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. Synthesis of N-su...
