The coating surface density of electrode sheets is typically adjusted using a ‘trial-and-error’ method. This method involves coating a sheet, drying it, and testing to confirm whether the desired surface density has been achieved. If not, the coating blade is adjusted, and the process is repeated multiple times until the target surface density is met. During the multiple adjustments to achieve the desired surface density, the following issues may arise:
- The slurry may dry prematurely, forming particles that cause scratches on the coating;
- Prolonged drying time increases operation time.
In response to this, our company has developed a rapid drying oven for electrode sheets.
The following example compares the drying times between a conventional forced-air drying oven and the rapid electrode drying oven developed by our company (cathode coating surface density: 21.2 mg/cm², anode coating surface density: 9.8 mg/cm²). As shown, the drying time required by the latter is an order of magnitude lower than the former, achieving the effect of drying the electrode sheet in just 2 minutes.
The specific features and parameters of the rapid electrode drying oven are as follows:
The advantages of our rapid electrode drying oven are as follows:
- It enables rapid drying of electrode sheets, significantly improving experimental efficiency;
- It incorporates a segmented drying rate design, inspired by production-scale coating machine ovens: the initial stage has a slow drying rate to prevent adhesive floating and slurry flow that could lead to uneven surface density, the middle stage has a fast drying rate to enhance drying efficiency, and the final stage has a moderate drying rate to prevent over-drying at the edges of the electrode sheets;
- The compact design makes it suitable for use in space-limited laboratories or work areas;
- Its small size means that heat can be concentrated more easily, allowing it to reach the set temperature faster, thereby achieving more efficient drying;
- The relatively low power consumption helps reduce energy use and minimize environmental impact.
Finally, Kolod is committed to ensuring your success in the journey of scientific research. Our company focuses on:
- Experimental equipment sales and research as our main business;
- Pilot testing services as our technical driving force;
- Careful selection of experimental materials as our market foundation.
