Problems solved by technology

First of all, it is easy to volatilize and leak in high temperature environment, which has a great impact on life and stability. Under high temperature and high pressure, the electrolyte may vaporize instantaneously, and the volume increases to cause explosion (that is what we often call explosion); secondly, The ionic conduction method used in the electrolyte has a very low conductivity, only 0.01S (conductivity, the reciprocal of ohm) / CM, which causes the ESR value (equivalent series resistance) of the capacitor to be particularly high

Abstract

The invention discloses a rapid multi-element analysis test method for an electrolyte. Through reagent preparation, reagent prearrangement and sample determination steps and a standard solution configuration, a blank, a reference, a standard concentration and a reading are pre-input into a computer, and through reagent preparation and testing after prearrangement, test data can be obtained perfectly, and a rapid test function can be realized, and various parameters are obtained; as long as the concentration of the reagent does not change and the standard concentration does not change, the parameters can be used for a long time, the blank and the reference are not needed every day, and only a sample is made; and the analysis and test data is accurate, the method is reasonable in step design, and the functions of the method are effectively realized.

Description

technical field [0001] The invention relates to the field of electrolyte multi-element technology, in particular to a rapid analysis and testing method for electrolyte multi-element. Background technique [0002] Electrolyte is a term with a wide range of meanings. It is used in different industries to represent different contents. There are electrolytes (also known as electrolytes) in living organisms, electrolytes used in the battery industry, and electrolytes in electrolytic capacitors, supercapacitors and other industries. [0003] The composition of electrolytes used in different industries varies greatly, or even completely different. For example, the electrolyte of the human body is mainly composed of water, sodium chloride, and pH buffer substances. The electrolyte of aluminum electrolyte capacitors contains GBL and other main solvents. The electrolyte of supercapacitors contains propylene carbonate or acetonitrile as the main solvent. The liquid contains main solv...
