Изобретение относитс  к электротехнической промышленности и может быть использовано при производстве щелочных никель-железных аккумул торов.The invention relates to the electrical industry and can be used in the production of alkaline nickel-iron batteries.

Известен сиособ сборки щелочиого никельжелезного аккумул тора иутем разделени  разноименных электродов сеиараторами, установки в сосуд, введени  сернистого соединени  в электролит и заливки его в аккумул тор 1. Сера  вл етс  активатором железного электрода . Однако при введении сернистого соединени  в электролит снижаетс  его активирующее действие. В св зи с этим серу ириходитс  вводить дополнительно.A known method for assembling an alkaline nickel-iron battery and separating opposite electrodes with seiators, installing them in a vessel, introducing a sulfur compound into the electrolyte and pouring it into battery 1. Sulfur is an activator of the iron electrode. However, when a sulfur compound is introduced into the electrolyte, its activating effect decreases. In connection with this, sulfur will be additionally introduced.

Наиболее близким по технической сущности и достигаемым результатам  вл етс  сиособ сборки щелочного никель-железного аккумул тора иутем разделеии  разноименных электродов сепараторами, введени  сернистого соединени , установки в сосуд и засыпки твердои щелочи 2. Сернистое соединение ввод т непосредственно в активную массу железного электрода. Однако нри этом сера окисл етс  и готовые аккумул торы при приведении их в действие не отдают требуемой по номиналу емкости.The closest in technical essence and achievable results is the method of assembling an alkaline nickel-iron battery and separating dissimilar electrodes with separators, introducing a sulfur compound, installing into a vessel and filling solid alkali 2. The sulfur compound is introduced directly into the active mass of the iron electrode. However, sulfur is oxidized by this and finished batteries, when activated, do not give up the required capacity.

С целью обеспечени  сохранности зар да иредложено сернистое соединение вводить одновременно с твердой щелочью в виде их смеси.In order to ensure the safety of the charge, and a deposited sulfur compound is introduced simultaneously with the solid alkali in the form of their mixture.

В качестве Сернистого соединени  IOжeт быть вз т сульфид железа, тиосульфат натри . При этом количество серы составл ет в среднем 0,1% S/Fe. При приведении в действие аккумул тор заливают электролитом, состо щим из раствора гидроокиси иатри  удельного веса 1,18-1,20 г/см с добавкой 5 г/л гидроокиси лити . При этом исключаетс  возможность окислени  серы. Сернистое соединение переводитс  в растворимое состо ние при заливке электролитом в самый иоследний момент- при ириведении аккумул тора в действие.Iron sulfide, sodium thiosulfate can be used as the sulfur dioxide compound. The amount of sulfur is on average 0.1% S / Fe. When actuated, the battery is filled with electrolyte consisting of a sodium hydroxide solution with a specific gravity of 1.18-1.20 g / cm with the addition of 5 g / l lithium hydroxide. This eliminates the possibility of sulfur oxidation. The sulfur compound is transferred to a soluble state when it is filled with electrolyte at the very last and last moment when the battery is activated.

Проведенные испытани  показали, что аккумул тор , изготовленный по предложенному способу, отдает емкость выше номинальной на ирот жении 900 циклов, в то врем  как аккумул тор , изготовленный по способу, вз тому за прототии, имеет иониженную емкость из-за дезактивации сернистого соедииени  и только после дополнительного введени  серы емкость достигает требуемого уровн .The tests carried out showed that the battery manufactured by the proposed method gives up a capacity higher than 900 cycles for a nominal period, while the battery made according to the method taken as a prototype has an ionized capacity due to the deactivation of the sulfur compound and only after additional introduction of sulfur, the capacity reaches the required level.
