Description
проводимость за счет создани примесных уровней и электроактивность за счет снижени энергии активации, что способствует значительному снижению пол ризации электрода , особенно при больших плотност х тока.conductivity due to the creation of impurity levels and electroactivity due to a decrease in the activation energy, which contributes to a significant decrease in the polarization of the electrode, especially at high current densities.
Кроме того, наличие в порах электрода некоторого количества SO2, образующегос в процессе восстановлени закиси меди, способствует предотвращению полимеризации электролита , что увеличивает сохранность источника тока.In addition, the presence in the pores of the electrode of a certain amount of SO2, which is formed during the reduction of copper oxide, helps to prevent the polymerization of the electrolyte, which increases the safety of the current source.
Порообразование в электроде осуществл етс путем возгонки из электрода излищней серы .Pore formation in the electrode is carried out by sublimation of excess sulfur from the electrode.
Таким образом, в порах электрода не содержитс вещества, следы которого преп тствовали бы прохождению электрохимической реакции.Thus, no substance is contained in the pores of the electrode, traces of which would prevent the passage of an electrochemical reaction.
Предмет изобретени Subject invention
Способ изготовлени медносульфидного электрода химического источника тока путем смешивани порошка меди и серы, вз тых в полутора-двукратном соотношении против стехиометрического , спрессовывани полученной смеси с металлической основой с последующим нагреванием, отличающийс тем, что, с целью улучшени электрических характеристик , порошок меди перед смешиванием нагревают на воздухе до температуры 160- 170°С и выдерживают при этой температуре 10-15 мин.A method of making a copper sulphide electrode of a chemical current source by mixing copper and sulfur powder, taken in a 1.5 to 2 times anti-stoichiometric ratio, pressing the resulting mixture into a metallic base and then heating, in order to improve the electrical characteristics, the copper powder is heated before mixing in air to a temperature of 160-170 ° C and maintained at this temperature for 10-15 minutes.
