This article will analyze the composition, working principle, and causes of electrolyte drying.

1、 The working principle of electrolytic capacitor is that it is a capacitor composed of two electrodes immersed in electrolyte. When a voltage is applied, the electrolyte will ionize, forming positive and negative ions. These ions will move between the electrodes under the action of an electric field, forming an electric current. The generation and storage of this current enable electrolytic capacitors to have the ability to store charges.

2、 The composition of electrolyte is an important component of electrolytic capacitors, and its composition determines the performance of electrolytic capacitors. Electrolyte is mainly composed of solvents and solutes. Common solvents include water, organic solvents, etc., while solutes can be electrolytes or non electrolytes. Electrolytes are substances that can ionize in solvents to produce positive and negative ions, such as acids, bases, and salts. Non electrolytes are substances that cannot be ionized, such as organic compounds.

3、 The reason for electrolyte dryness refers to the evaporation or removal of solvents in the electrolyte by other means, resulting in an increase in solute concentration in the electrolyte and affecting the performance of electrolytic capacitors.

Here are several possible reasons that may cause electrolyte to dry up:

1. High temperature: High temperature can enhance the thermal motion of solvent molecules, thereby accelerating the evaporation rate of the solvent. When electrolytic capacitors are exposed to high temperatures for a long time, the evaporation rate of solvents will accelerate, causing the electrolyte in the electrolytic capacitor to dry up.

2.  Electrolyte leakage: During the use of electrolytic capacitors, if they are subjected to external force collisions or mechanical damage, it is easy to cause electrolyte leakage. Once the electrolyte leaks, the solvent will be lost, causing the electrolyte to dry up.

3. Long storage time: During long-term storage of electrolytic capacitors, the solvent in the electrolyte will gradually evaporate, causing the electrolyte to dry up.

4. Improper use conditions: If electrolytic capacitors are used in high humidity environments, the evaporation rate of solvents will slow down, thereby reducing the risk of electrolyte drying up. But if electrolytic capacitors are used in low humidity environments, the evaporation rate of solvents will increase, which can easily cause the electrolyte to dry up.

5. Inappropriate electrolyte composition: Some solvents in electrolytes have high volatility, which can easily cause the electrolyte to dry up. Therefore, when selecting electrolytes, suitable solvents should be chosen based on specific usage conditions and requirements.

4、 How to avoid electrolyte drying up? To prevent electrolyte drying up, the following measures can be taken:

1. Control the usage environment: Avoid exposing electrolytic capacitors to excessively high temperatures, especially in enclosed spaces or places directly exposed to sunlight.

2. Pay attention to electrolyte leakage: When using electrolytic capacitors, care should be taken to avoid collisions or mechanical damage to prevent electrolyte leakage.

3. Reasonable storage and use: Electrolytic capacitors that have not been used for a long time should be stored in a low temperature and low humidity environment to reduce solvent evaporation. During use, prolonged high-temperature operation should be avoided.

4. Choose the appropriate electrolyte: Select the appropriate electrolyte based on specific usage conditions and requirements. For some special application scenarios, solvents with lower volatility can be chosen. The dry electrolyte is caused by solvent evaporation or leakage in electrolytic capacitors, mainly related to factors such as temperature, storage time, usage conditions, and electrolyte composition. In order to prevent the electrolyte from drying up, it is necessary to control the usage environment reasonably, pay attention to electrolyte leakage, store and use it reasonably, and choose a suitable electrolyte. This is the only way to ensure the normal operation and performance of electrolytic capacitors.
