Abstract: PURPOSE: An organic-inorganic composite oxide for the cathode of a lithium secondary battery and its preparation method are provided, which is improved in the charging-discharging effect by intercalating different polymers into V2O5 xerogel. CONSTITUTION: The organic-inorganic composite oxide comprises V2O5 xerogel where poly(2,5-dimercapto-1,3,4-thiadiazole) and polyaniline are intercalated. Preferably the ratio of V2O5 xerogel : poly(2,5-dimercapto-1,3,4-thiadiazole) : polyaniline is 1 : 0.2-1 : 0.2-2 by mol. The method comprises the steps of preparing powdered V2O5 xerogel; dissolving the powdered V2O5 xerogel into distilled water to obtain a V2O5 aqueous solution; dissolving 2,5-dimercapto-1,3,4-thiadiazole monomer into an organic solvent to obtain a 2,5-dimercapto-1,3,4-thiadiazole solution; adding the V2O5 aqueous solution to the 2,5-dimercapto-1,3,4-thiadiazole solution slowly; adding aniline to the obtained one; stirring the obtained one at a room temperature for 24 hours, filtering it under reduced pressure and washing it; and drying the product at a room temperature or 80 deg.C.

Abstract: PURPOSE: A smart card embedding a super capacitor is provided to enable a rapid charge or an instant discharge at a remote place as well as by a wired connection by using the super capacitor for supplying electric power to a signal process circuit so that it can make only the card itself perform a data process. CONSTITUTION: The smart card comprises a super capacitor(SC), an antenna coil(A), a low pass filter(F), external connectors(11,12), a diode and an IC element(IC). Electromagnetic waves are received by the antenna coil(A), rectified in the diode, transferred to the low pass filter(F), filtered in the low pass filter(F), and converted to DC voltage signals. The DC voltage signals charge the super capacitor(SC). The super capacitor(SC) can be charged also via the external connectors(11,12). The super capacitor(SC) supplies necessary power to the IC elements for processing data or generating signals to external devices. The super capacitor has a specific capacity larger than a conventional capacitor by 100 to 1000, and a power density larger than the latest secondary battery by 10 more so that it can rapidly store the electric power.
