Description
Предметом насто щеп,) изобретени вл етс способ восстановлени потер нной емкости щелочных калмиево-никелевых аккумул торов.The subject of the present invention is a method of restoring the lost capacity of alkaline nickel-calmea batteries.
В технике известны снособы восстановлени емкости иделочных аккумул торов , заключаюнщес в c.icдующем:In the technique, the restoration of the capacity of the capacitor batteries and of the batteries, known in c.
1.Аккумул торы разогреваю с электрическим током ночти до кинени электролита, при этом восстанавливаемые электроды слу) катодом и на них выдел етс водород, корнус же аккумул тора вл етс нерастворимым анодом (патент Эдиссона Л° 177772, кл. 21 в, гр. 25 от 11 декабр 1904 г.).1. The accumulators are heated with an electric current the night before the electrolyte is kinized, and the electrodes to be repaired under the cathode and hydrogen is released on them, while the corona of the battery is an insoluble anode (Edisson P patent 177772, CL 21 in, gr. 25 from December 11, 1904).
2.В электролит вводитс значительное количество едкого лити до 60 г/л.2. A significant amount of caustic lithium up to 60 g / l is introduced into the electrolyte.
3.Аккумул торы, работавшие на электролите из едкого кали, перевод тс на электролит из едкого натра.3. Accumulators operating on caustic potash electrolyte are converted to caustic soda electrolyte.
Предлагаемый способ дает более полное восстановление CNHVOCTH аккумул торов и удлин ет срок их службы.The proposed method provides a more complete recovery of CNHVOCTH batteries and prolongs their service life.
Сунлность предлагаемого способа заключаетс в следующем.The sufficiency of the proposed method is as follows.
Восстанавливаем ыГ1 аккумул тор разр жаетс в старом электролите до напр жени npHNsepHo 0,3 вольта, после чего производитс тщательна трехкратна промывка аккумул тора дистиллированно ВОДО11. ПриWe restore the battery in an old electrolyte to a voltage of 0.3 volts, which is then discharged, after which the battery is thoroughly washed three times with WODO11. With

При кип чении происходит разрыхление активно .;ассы и бол(;:е но.июе удаление кристаллических отложенгн н вредных примесей из пластин. После кип чени аккумул тор промываетс еще раз дистиллированной водой, иросущиваетс на воздухе, заливаетс раствором едкого натра уд. веса 1,21 и зар жаетс по двухступенчатому режиму.the second and TpeTheii for, the H1vka battery remains filled with i water for two to four hours. The battery is then boiled in .-; irovirovano vods for one hour. During boiling, loosening is active.; Assy and bol (;: no., Removal of crystalline deposits of harmful impurities from the plates. After boiling, the battery is rinsed again with distilled water, dehydrated in air, poured with caustic soda solution of specific weight 1 , 21 and charged in a two-step mode.
1- ступень-зар дка производитс нормальным зар дным током в течение 10 часов, после чего с.1едует 2-часовой перерыв.The 1-step charge is made with a normal charging current for 10 hours, after which p.1 leads to a 2-hour break.
2- ступе пь-зар дка производитс в течение 6 часов током, равным половине нормального зар дно .№ 96933-- 2 -то тока. По истечении времени за-производитс нормальный зар дA 2-step pu-charge is produced for 6 hours with a current equal to one-half the normal charge. No. 96933-- 2 is a current. After a time has elapsed, a normal charge is generated.
