Изобретение относитс к области электротехники .This invention relates to the field of electrical engineering.
Известен способ заполнени активной массой пористых основ окисно-никелевых электродов щелочных акку.мул торов путем пропитки в растворах сульфата н икел с одновременной катодной пол ризацией в ра.створах нитрата н кел . Однако пр.и такоМ стособе основной операции введени активной массы в пористую основу с одновременной катодной -пол ризацией предшествуют предварительные операции введени депол ризатора. Дл получени средней емкости 0,65 а-час/м ци.кл обработки составл ет 90-98 час.The known method of filling the active mass of porous bases with nickel oxide electrodes of alkaline battery by impregnation of nickel in solutions of sulphate with simultaneous cathodic polarization in solutions of nitrate and nel. However, the precursors of introducing a depolarizer precede the main operation for introducing the active mass into the porous base with simultaneous cathode polarization. In order to obtain an average capacity of 0.65 a-h / m cw, the treatment is 90-98 hours.
Предлагаемый способ отличаетс от известного тем, что дл упрощени технологии перед пропиткой основы ее предварительно подвергают пол ризации асимметричным током промышленной частоты с р-авными временами катодного и анодного полупериодов в водном растворе едкого кали (КОН) при плотност х тока в катодный лолупериод 0,8 afcM. в анодный 0,41 а/см.The proposed method differs from the well-known fact that, in order to simplify the technology, before impregnating the base, it is first subjected to polarization with an asymmetric current of industrial frequency with p-avny times of the cathode and anodic half-periods in an aqueous solution of caustic potash (KOH) at current densities of 0.8 cathode loluperiod afcM. to anode 0.41 a / cm.
СпосОб осуществл ют следующим образом.The method is carried out as follows.
Металлокерамическую никелевую основу с пористостью -75-85% и толщиной 0,20- 0,25 мм пол ризуют в водном растворе щелочи (1,5-2,5 N КОН) при 20-30° С асимметричным током промышленной частоты (50 гц) при плотност х тока в катодный пол}период 0.8 а/слг2, в анодный 0,41 асм (амплитздные значени ) в течение 30 мин.A cermet nickel base with a porosity of -75-85% and a thickness of 0.20-0.25 mm is polarized in an aqueous solution of alkali (1.5-2.5 N KOH) at 20-30 ° C with an asymmetric current of industrial frequency (50 Hz ) at current densities in the cathode field} period 0.8 a / sg2, in the anodic one, 0.41 asm (amplitude values) for 30 minutes.
Затем электроды зар жают в том же растворе , отмывают в воде от щелочи, сущат и пропитывают в растворе сульфата никел (NiSO.i) плотностью ,6-1,7 г,см при 80° С с одновременной катодной лол ризацией током ПЛОТНОСТЬЮ 10-20 ма/см. Процесс пропитки прекращают -при достижении потенциала выделени Никел . Продолжительность всех операций 13 час.Then the electrodes are charged in the same solution, washed in water from alkali, they are saturated and impregnated in a nickel sulphate (NiSO.i) solution with a density of 6-1.7 g, cm at 80 ° С with simultaneous cathode polarization with a current of DENSITY 10- 20 ma / cm The impregnation process is stopped when the nickel release potential is reached. The duration of all operations is 13 hours.
