TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Compound: Ionic monomer is a molecular salt of formula (I).P1,P2=polymerizable functional group;Y1-,Y2-=organic group having anion;andR1-R9=(un)substituted alkyl, alkenyl, aryl, aralkyl, aralkenyl, alkoxy alkyl and acyloxy alkyl optionally having ring system including hetero atom, where one or more of R1-R4 or R6-R9 optionally forms a cyclic structure. EXAMPLE - 1,2-ethanedisulfonic acid (in g) (4.76) was dissolved in methanol (500 ml). Then, silver carbonate (27.6) was added, stirred at room temperature for 4 hours and filtered, to obtain colorless and transparent solution. The solution obtained by dissolving methacryl amidopropyl trimethyl ammonium chloride (101 mmol) in methanol (100 ml) was dripped to the colorless solution and reacted. Silver chloride was separated by filtration and colorless and transparent methanol solution was recovered. The filtrate was evaporated under reduced pressure and a viscous ionic monomer of formula (II) was obtained. Tetrahydrofuran (10), benzoyl peroxide (0.8) as polymerizable initiator and lithium perchlorate (0.1) were added to the obtained ionic monomer (4.2) and coating composition was prepared. The obtained composition was coated on flat plate of Teflon (RTM: polytetrafluoroethylene resin) having thickness of 0.5 microns and polymerized at 80degrees C for 4 hours, to obtain ionic conductive electrolyte having conductivity of 1.8x10-4 S/cm at 20degrees C. N-methyl pyrrolidone, graphite (in wt.%) (5), polyvinylidene fluoride (10) and lithium cobalt oxide (85) were mixed to form a slurry, coated to aluminum foil, and rolled to obtain anode. N-methyl pyrrolidone, graphite (90) and polyvinylidene fluoride (10) were mixed to form slurry, coated to copper foil, and rolled to obtain cathode. A secondary battery was formed using the obtained anode, cathode and lithium ionic conductive electrolyte. The battery had discharge capacitance of 100% and capacitance maintenance factor after 100 cycles of 90%.
