Abstract
Present study describes synthesis, characterizations and electrochemical properties of novel materials or novel approaches of preparation and their testing for suitability in industrial application. Work is divided into two main groups. First group is focused on preparation and characterization of ion-exchange membranes and second group is focused on preparation and characterization of ionic liquids.
Prepared ion-exchange membranes are further split in two subgroups:
a) Anion exchange membrane - synthesis and characterization of chloromethylene polystyrene-block-poly(ethylene-ran-butylene)-block-polystyrene copolymer, which was tested in water alkaline electrolysis
b) Cation exchange membrane – synthesis and characterization of:
i. poly(vinyl phosphonic acid-co-acrylonitrile), which was tested in fuel cells ii. polystyrene-block-poly(ethylene-ran-butylene)-block-polystyrene with
sulfomethyl group, which was tested for use in microbial electrolysis Prepared ionic liquids are also divided into three groups based on the main function group:
a) Imidazolium – ethyl methyl imidazolium phosphonic acid ethyl ester
b) Phosphonium – methyl tributyl phosphonium bis (trifluoromethyl sulfonyl) imide c) Sulfonium – trimethyl sulfonium bis (trifluoromethyl sulfonyl) imide
Ionic liquids were synthesized and characterized, different types of lithium salt were added and obtained electrolytes were measured for electrochemical properties as a potential feasible electrolyte used in lithium-ion batteries.
