Металлокерамические окисноникелевые электроды дл щелочных аккумул торов изготавливают путем пропитки пористой основы з растворе азотнокислого никел с последующей обработкой в щелочи. Однако процесс пропитки продолжителен, а электрические характеристики электродов невысокиеЦель изобретени - интенсификаци процесса пропитки металлокерамических основ электродов в растворе азотнокислого никел .Metal-ceramic nickel oxide electrodes for alkaline batteries are made by impregnating a porous base with a solution of nickel nitrate followed by treatment in alkali. However, the impregnation process is long, and the electrical characteristics of the electrodes are not high. The purpose of the invention is to intensify the impregnation process on the metal-ceramic bases of the electrodes in a solution of nickel nitrate.
Это достигаетс совместным применением пропитки в течение трех циклов при плотности раствора 1,70-1,72 , рН 1,0-1,5; 1,5- 2,0; 2,0-3,0 соответственно по циклам, температуре 85-90°С и продолжительности каждого цикла 2 час.This is achieved by the combined use of impregnation for three cycles at a solution density of 1.70-1.72, pH 1.0-1.5; 1.5-2.0; 2.0-3.0, respectively, according to cycles, temperature 85-90 ° С and duration of each cycle 2 hours.
Сущность предложенного способа заключаетс в следующем.The essence of the proposed method is as follows.
Металлокерамические основы окисноникелевого ЭоТектрода пропитывают в течение трех циклов в растворе азотнокислого никел при 85-90°С. Плотность раствора дл пропитки 1,70-,72 г/см при 90°С рН раствора перед первой пропиткой - 1,0-1,5, перед второй - 1,5-2,0 и перед третьей - 2,0-3,0. Продолжительность каждого цикла пропитки - 2 час.Metal-ceramic bases of the oxide-nickel EoTectrode are impregnated for three cycles in a solution of nickel nitrate at 85-90 ° C. The density of the impregnation solution is 1.70-, 72 g / cm at 90 ° C. The pH of the solution before the first impregnation is 1.0-1.5, before the second - 1.5-2.0 and before the third - 2.0-3 , 0. The duration of each impregnation cycle is 2 hours.
После пропитки электроды выдерживают 0,5 час в кристаллизаторе, после чего 1,5 час обрабатывают щелочью плотностью 1,19- 1,21 г1см при температуре 90°С. Затем подвергают в течение 0,5 час 6-7-кратной промывке дистиллированной водой при 50-60°С и сущат в течение 1,0-1,5 час при 90-110° С. Изготовленные таким образом электроды взвешивают дл определени привеса активной массы.After impregnation, the electrodes are kept for 0.5 hour in a crystallizer, after which they are treated for 1.5 hour with alkali with a density of 1.19-1.21 g1 cm at a temperature of 90 ° C. It is then subjected to washing for 6 hours 6-7 times with distilled water at 50-60 ° C and maintained for 1.0-1.5 hours at 90-110 ° C. The electrodes thus produced are weighed to determine the active weight gain. masses.
Предлол енный способ позвол ет сократить врем пропитки в 2,5-3 раза при увеличении е.мкости электрода на 10%.The predlozhenny method allows to reduce the impregnation time by 2.5-3 times with an increase in the electrode capacitance of 10%.
