DOUBLE-LAYER CAPACITOR Russian patent published in 2001 - IPC

FIELD: electrical engineering. SUBSTANCE: capacitor has electrodes whose composition is modified by adding metal dioxide particles measuring 1-50 mcm in the amount of 1-10 volume percent. These particles are chosen from group of metals TiO₂, SiO₂, PbO₂, SnO₂ or their mixtures. Selected separator has different porosity through its thickness; pore size of external layers of separator used for shaping electrodes is from 5 to 100 mcm; that of intermediate layer of separator is below 5 mcm or does not exceed size of activated carbon particles; its thickness is 5-30 mcm and it incorporates moisture-absorbing material particles chosen from group of metals TiO₂, SiO₂ or their mixture. EFFECT: reduced internal resistance and enhanced specific power characteristics of capacitor. 4 cl, 3 dwg
