Description
Обычно изготовл емые щелочные аккумул торы имеют существен ый недостаток - ограниченную работоспоеобность при отрицательных температурах окружающей среды.Typically manufactured alkaline batteries have a significant drawback - limited operability at low ambient temperatures.
Описываемый способ изготовлени активной массы отрицательных электродов щелочных аккумзл тороз позвол ет устранить указанный недостаток . Это достигаетс путем механического смешивани окиси кадми е гидратом никел , предварительно размолотым на вибромельнице, что упрощает технологию изготовлени и повыщает емкость аккумл-л тора при работе его в услови х отрицательных температур.The described method of manufacturing the active mass of the negative electrodes of alkaline batteries makes it possible to eliminate this drawback. This is achieved by mechanically mixing cadmium oxide with nickel hydrate, previously ground in a vibrating mill, which simplifies the manufacturing technology and increases the capacity of the battery when it is operating at negative temperatures.
-Так как величина саморазр да аккумул торов определ етс саморазр дом иоложительного электрода, допустимо хранение таких зар женных аккумул торов при высоких температурах. Остаточна емкость после 30-суточного хранени аккумул торов в зар женном состо нии при + 60 составл ет соответственно 68% и 52% дл аккумул торов без железной составл ющей и с лселезной составл ющей в массе отрицательного электрода. Емкость при -40 возрастает по сравнению с существуюИ1ими аккумул торами более чем в два раза при плотности тока 0,66 а/д..-. Возможна герметизаци аккумул торов ио окончании зар да npii температурах окружающей среды ниже -f 15°. При повыщениых температурах герметическа укупорка аккумул торов допустима после иекоторого сн ти емкости (пор дка 15%).- Since the amount of self-discharge of batteries is determined by the self-discharge of a positive electrode, storage of such charged batteries at high temperatures is permissible. The residual capacity after 30-day storage of batteries in a charged state at + 60 is 68% and 52%, respectively, for batteries without an iron component and with a battery component in the mass of the negative electrode. Capacity at -40 is more than doubled compared to existing batteries at a current density of 0.66 a / d ..-. Batteries can be sealed by terminating the charge of npii ambient temperatures below –15 °. At elevated temperatures, hermetic sealing of batteries is permissible after some removal of capacity (about 15%).
Особенно эффективно использование таких аккумул торов в странах с жарким климатом, а также в иереносных установках, где недопустимо .вытекание щелочи из аккумул торов на аппаратуру.The use of such batteries is especially effective in countries with a hot climate, as well as in horny installations where it is unacceptable to leak alkali from batteries to equipment.
