What are the main factors affecting electrode paste sintering?
The main factors affecting electrode paste sintering include:
The height of electrode paste column: The height of electrode paste column will affect the volatilization rate of electrode paste volatiles. The higher the paste column, the slower the volatilization rate of volatile matter, and the slower the electrode sintering speed. Therefore, it is necessary to control the height of the electrode paste column appropriately to ensure the appropriate sintering speed.
Electrode current: The electrode current has a decisive impact on the sintering speed of the electrode. The higher the current, the faster the sintering speed. This is because the resistance heat generated by the electrode current is directly proportional to the square of the electrode current. The larger the current, the greater the resistance heat, thereby accelerating the sintering process of the electrode paste.
In addition to the above two main factors, there are also other factors that may affect the sintering of electrode paste, such as the composition, quality, kneading uniformity, pressing process, etc. These factors will have a certain impact on the sintering process of electrode paste, thereby affecting the conductivity, oxidation resistance, sintering density, and consumption rate of the electrode.
