前言目前广泛应用的汞-镉汞齐饱和式标准电池,电池电动势温度系数大,电池使用时必须维持在一均衡的温度环境中。不饱和式标准电池,虽其温度系数可以获得接近于零,但年平均电动势变化约85μV,同时电动势变化后不能再生。近年来在饱和标准电池的镉汞齐中掺入了Pb、Sn、Bi或Sn-Pb,降低了电池的温度系数,但一般仍在13μV/K以上。本文介绍一种新型的钠-低钠汞齐固体电解质标准电池,在一定组成和温度范围内其电动势温度系数接近于零。因为钠β氧化铝固体电解质的电子电导极其微小,化学稳定性好,
Preface At present, the mercury-cadmium amalgam saturated standard battery, which is widely used, has a large temperature coefficient of battery electromotive force and must be maintained in a balanced temperature environment when the battery is used. Unsaturated standard battery, although the temperature coefficient can be obtained close to zero, but the average annual change of about 85μ V, at the same time change the electromotive force can not be regenerated. In recent years, cadmium amalgam saturated with standard batteries incorporation of Pb, Sn, Bi or Sn-Pb, reducing the temperature coefficient of the battery, but generally still above 13μV / K. This article describes a new type of sodium - sodium amalgam solid electrolyte standard battery, in a certain composition and temperature range of its electromotive force temperature coefficient close to zero. Because sodium β alumina solid electrolyte extremely small electronic conductivity, good chemical stability,
