Description
Изобретение относитс к электротехнической промышленности и может ч быть использовано при производстве герметичных никель-кадмиевых аккумул торов .The invention relates to the electrical industry and can be used in the manufacture of sealed nickel-cadmium batteries.
Известен способ восстановлени емкости отработанных окисно-никелевых электродов щелочного аккумул тора путем обработки раствором сахара или смесью глицерина, с винным спиртом с последующим зар дом.A known method of restoring the capacity of spent nickel oxide electrodes of an alkaline battery by treating with a sugar solution or a mixture of glycerin, with wine alcohol, followed by charging.
Однако этот способ не обеспечивает полного восстановлени из-за того, что используемые дл обработки веще,ства вл ютс слабыми восстановител ми .However, this method does not provide complete reduction due to the fact that the substances used for processing are weak reducing agents.
Наиболее близким-по технической сущности и достигаемым результатам вл етс способ восстановлени емкости отработанных окисно-никелевых электродов щелочного аккумул тора путем обработки в растворе гидуThe closest in technical essence and the achieved results is a method of restoring the capacity of spent oxide-nickel electrodes of an alkaline battery by processing in solution a guide
роокиси кали КОН с добавкой гидроокиси лити LiOH в течение 6ч с проведением формировочных циклов.potassium hydroxide KOH with the addition of lithium hydroxide LiOH for 6 hours with the formation of cycles.
отот способ требует использовани составного электролита и длительной обработки.This process requires the use of a composite electrolyte and lengthy treatment.
ОABOUT
Целью изобретени вл етс упрощесо ю ние технологии.The aim of the invention is to simplify the technology.
Это достигаетс тем,что в качест00 ве щелочи берут 1-2%-ный раствор амVJ миака и обработку ведут в течение 0,1-0,5 ч с последующей отмывкой и This is achieved by the fact that, as an alkali, they take a 1-2% solution of amVJ miak and the treatment is carried out for 0.1-0.5 hours, followed by washing and
сушкой.by drying.
Пример 1. Из отработанных аккумул торов марки НКГК-11Д извлекают металлокерамическИе окисно-никелёвые электроды, обрабатывают в 1%-ном растворе аммиака в течение 0,1 ч, отмывают водой и высушивают при в течение 3 ч.. Затем о кисно-никеле вые электроды в комплекте со свежеизготовленными кадмиевыми электроламп сепарируют , вставл ют в металлический корпус аккумул тора, заливают электролитом (кон - LiOH), отформировывают и герметизируют- Емкость электрода 1,9 Л-ц.Example 1. Metal-ceramic oxide-nickel electrodes are removed from spent batteries of the NKGK-11D brand, treated in a 1% solution of ammonia for 0.1 h, washed with water and dried for 3 hours. Then, acid-nickel the electrodes complete with freshly made cadmium lamps are separated, inserted into the metal housing of the battery, filled with electrolyte (con - LiOH), formed and sealed. The electrode capacity is 1.9 L-c.
Пример 2. Поступают, как в примере 1, обрабатыва электроды в 1,5%-ном растворе аммиака в течение Example 2. Act as in example 1, processing the electrodes in a 1.5% solution of ammonia for
0,3 ч.0.3 hours
Пример 3. Аналогично примеру 1 обрабатывают электроды в 2%-ном растворе аммиака в течение 0,5 ч.Example 3. Analogously to example 1, the electrodes are treated in a 2% ammonia solution for 0.5 hours.
После обработки электродов из отработанных аккумул торов марки НКГКПЛ раствором аммиака концентрацией 0,8, 2,0, 1,0, 1,0, 2,0 и 2,2% а течение 0,1., 0,1, 0,05, 0,5, 0,7 иAfter processing the electrodes from spent batteries of the NKGKPL brand, a solution of ammonia with a concentration of 0.8, 2.0, 1.0, 1.0, 2.0 and 2.2% and a flow of 0.1., 0.1, 0.05 , 0.5, 0.7 and
0,5 ч соответственно емкость-электро да составл ет 1,80, 1,93, 1,80, 1,920.5 h, respectively, the capacitance-electrode is 1.80, 1.93, 1.80, 1.92
1,9 и 1,93 Л.ч. Емкость отрабо ан с го и свежеприготовленного электродов 1,60 и 1,90 Л..ч соответственно.1.9 and 1.93 L.H. The capacity of the spent and freshly prepared electrodes was 1.60 and 1.90 L..h, respectively.
Таким образом, при применении раствора аммиака с концентрацией менее ,0% и длительности обработки менее 0,1 ч структура и активность массы восстанавливаютс не полностью При у времени обработки более 0,5-м возрастают расход Материала и длительность процесса, но характеристики электро- да не измен ютс .Thus, when using an ammonia solution with a concentration of less than 0% and a processing time of less than 0.1 h, the structure and activity of the mass are not completely restored. At a processing time of more than 0.5 m, the Material consumption and the process duration increase, but the electrode characteristics not change.
Электрические испытани электродов показывают, что емкость их после обработки в растворе аммиака возрастает до уровн свежеизготовленных электродов . При этом упрощаетс технологи так как используетс более простой noj); составу восстановитель и значительно сокращаетс врем восстайовлени .Electrical tests of the electrodes show that their capacity after processing in an ammonia solution increases to the level of freshly prepared electrodes. At the same time, the technology is simplified since a simpler noj) is used; the reductant and significantly reduces the recovery time.
