NOVELTY - A wet electrolytic capacitor (40) comprises anode (20), cathode (43) and working electrolyte (44). The anode contains tantalum, niobium or their electroconductive oxide. The cathode contains a coating disposed over the surface of the current collector. The coating contains electrochemically active particles and binder formed from amorphous polymer having glass transition temperature of 100 degrees C or more. The binder is in the form of particles with particle size distribution (D90) of 150 mu m or less. The electrolyte contains aqueous solution containing acid.    USE - Wet electrolytic capacitor used in defibrillators, automotive applications, military applications such as radar systems and in consumer electronics such as radio and television.    ADVANTAGE - The wet electrolytic capacitor has excellent electrical properties.    DETAILED DESCRIPTION - A wet electrolytic capacitor (40) comprises an anode (20), a cathode (43) and working electrolyte (44) disposed between cathode and anode. The anode contains tantalum, niobium or their electroconductive oxide. The cathode contains a coating disposed over the surface of the current collector. The coating contains electrochemically active particles and binder formed from amorphous polymer having glass transition temperature of 100 degrees C or more. The binder is in the form of particles having particle size distribution (D90) of 150 mu m or less. The electrolyte contains aqueous solution containing acid. The amorphous polymer is thermoplastic polyimide, preferably poly(amide-imide) and/or poly(ether-imide), more preferably poly(amide-imide) formed from trimellitic acid or its derivative and aromatic diamine. The electrochemically active particles contain metal, metal oxide and/or carbonaceous particles, and activated carbon. The coating further comprises conductive filler. The current collector contains a metal. The anode further contains electroconductive oxide of niobium and dielectric film containing niobium pentoxide.
