제목 Composite Polymer Electrolyte Incorporating Ionic Liquid with Organic Nanosheets for High Ionic Conductivity
초록 Conventional battery polymer gel electrolytes which is comprised with ionic liquid and lithium salt has limited ionic conductivity. One of the promising method to enhance ionic conductivity is incorporating inorganic fillers in polymer matrix to induce lewis acidic-basic interaction for lithium cations and promote dissociation of lithium salts. However, in order to well-disperse inorganic fillers into polymer matrix, interfacial coating or stabilizing agent is required. In this study, covalent organic framework organo nanosheets were synthesized to alter the function of inorganic fillers without any further interfacial treatments. C3-symmetric triaminoguanidine chloride was selected as platform to synthesize organo nanosheets. Thanks to C3-symmetric structure, organo nanosheets formed crystal morphology and following lithiation process serves interaction sites to help to improve ionic conductivity.
