NOVELTY - A mixed-type polymer super-capacitor comprises a positive plate, a negative plate and a polymer electrolyte membrane between the positive plate and negative plate. The positive plate comprises graphite, conductive carbon black and polyvinylidene fluoride. The negative plate comprises activated carbon, mesoporous carbon, carbon nano-tube, or carbon aerogel, conductive carbon black and polyvinylidene fluoride. The polymer electrolyte membrane is electrolyte membrane of gel-type polymer electrolyte comprising lithium salt, slurry component, and plasticizer.    USE - Mixed-type polymer super-capacitor.    ADVANTAGE - The mixed-type polymer super-capacitor has excellent workability.    DETAILED DESCRIPTION - A mixed-type polymer super-capacitor comprises a positive plate, a negative plate and a polymer electrolyte membrane between the positive plate and negative plate. The positive plate comprises graphite, conductive carbon black and polyvinylidene fluoride. The negative plate comprises activated carbon, mesoporous carbon, carbon nano-tube, or carbon aerogel, conductive carbon black and polyvinylidene fluoride. The positive plate further comprises lithium ion-containing compound chosen from lithium cobaltate, lithium manganese oxide, lithium nickel oxide, lithium iron phosphate, lithium-nickel-cobalt oxide (LiNi0.8Co0.2O2), or lithium-nickel-cobalt-manganese oxide (LiNi1/3Co1/3Mn1/3O2), or metallic element chosen from lithium, cobalt, nickel, manganese, iron, copper, aluminum, magnesium and zinc. The polymer electrolyte membrane is electrolyte membrane of gel-type polymer electrolyte comprising lithium salt, slurry component such as polyacrylonitrile, polyoxyethylene or polyvinylidene fluoride, and plasticizer. The lithium salt is chosen from lithium perchlorate, lithium tetrafluoroborate, lithium hexafluorophosphate, lithium trifluoromethanesulfonate (LiCF3SO3), or lithium bis (trifluoromethanesulphonyl) imide (LiN(CF3SO2)2). The plasticizer is chosen from ethylene carbonate, carbonic allyl ester, ethyl methyl carbonate, dimethyl carbonate and gamma -butyro lactone.
