Description
В гальванических элементах в качестве отрицательного электрода примен етс преимущественно металлический цинк. Цинк не обладает высоким электрохимическим потенциалом. Элементы с металлическим цинком не дают высокого напр жени , поэтому неоднократно ставилс вопрос об использовании более электроотрицательных металлов дл построени гальванических элементов. Попытки применить дл указанной цели магний не увенчались успехом, так как повышение электроотрицательного потенциала св зано или с ростом коррозии магни в одних электролитах или с пассивизацией магни в других электролитах.In galvanic cells, predominantly metallic zinc is used as a negative electrode. Zinc does not have a high electrochemical potential. Elements with metallic zinc do not give a high voltage, so the question was repeatedly raised about using more electronegative metals to construct galvanic cells. Attempts to use magnesium for this purpose were unsuccessful, since an increase in electronegative potential is associated either with an increase in magnesium corrosion in some electrolytes or with the passivation of magnesium in other electrolytes.
В предлагаемом гальваническом элементе с магниевым отрицательным электродом эти недостатки устранены.In the proposed galvanic cell with a magnesium negative electrode, these disadvantages are eliminated.
Согласно изобретению в предлагаемом элементе применен магний в виде сплава с ртутью в щелочном электролите.According to the invention in the proposed element is applied magnesium in the form of an alloy with mercury in an alkaline electrolyte.
Нормальна эксплуатаци предлагаемого элемента должна производитьс следующим образом: дл устранени коррозии магниевого электрода в разомкнутом состо нии необходимо перед выключением подвергать его анодному пассивированию, например при помощи короткого замыкани , а перед включением активировать кратковременной катодной пол ризацией или погруЯ ением электрода в воду или нейтральные растворы солей.Normal operation of the proposed element should be carried out as follows: to eliminate corrosion of the magnesium electrode in the open state, it is necessary to subject it to anodic passivation before switching off, for example, using a short circuit, and to activate it by short-term cathodic polarization or immersion of the electrode in water or neutral salt solutions .
