Problems solved by technology

[0008] The service life of the existing solid non-polarized electrodes is relatively short. When a pair of solid non-polarized electrodes is used for field measurements, the range of the electrodes often rises to more than ten or even tens of millivolts after several times of use.
Such electrodes cannot be used again and must be replaced with new solid non-polarizable electrodes

Abstract

The invention discloses a non-polarized electrode with service life prolonged by adding an electrolyte solution. The non-polarized electrode mainly comprises an electrode shell, a top cover, a partition plate with holes, a waterproof pipe, sponge, solid electrolyte, an isolation ring and a precursor electrode. According to the designed solid non-polarized electrode, three circles of small holes are additionally formed in the partition plate. When the electrode range rises, the electrolyte solution can be added to enable the solution to penetrate through the small holes to permeate and wet thesolid electrolyte, so that the electrode range is remarkably reduced, and the purpose of prolonging the service life of the electrode is achieved.

Description

technical field [0001] The invention relates to the field of semiconductors, in particular to a non-polarized electrode whose service life is extended by adding electrolyte solution. Background technique [0002] The copper sulfate electrode invented by Soviet scientist Semyonov in 1937 is the earliest and most common non-polarization electrode used in the world. Copper sulphate electrode has many disadvantages. Its use time is short, it is inconvenient to carry in the field, and it must be carefully preserved and cannot be beaten, which is extremely inconvenient for prospectors who work in the field for a long time. Since the 1970s, France, the United States, Germany, Canada and other countries have successively developed various electrodes such as lead chloride, cadmium chloride, mercury chloride, and silver chloride. However, these electrodes are the same as copper sulfate electrodes, and their common feature is to use the "liquid" non-polarized electrode formed by metal...
