A quantitative formula linking the roller diameter to the percentage elongation of the battery electrode was proposed considering the effect of the roller diameter. Additionally, through electrode cleaning experiments, the study identified the coordination relationship between the extension of the electrode coating and the current collector.
Excessive elongation not only compromises the flexibility of the battery electrodes but also leads to quality issues, such as coating edge wrinkles and electrode ear fractures. In practice, it is necessary to minimize the percentage elongation of the electrode, typically ensuring that it remains below 5 % .
Any deviation can lead to poor fitment and performance issues in the final application, be it in batteries, capacitors, or other energy storage devices. Material Handling: Electrode materials can be delicate and prone to damage during the slitting process.
During the calendering process of battery electrodes, different roller diameters correspond to different biting angles under the same compression rate. Smaller roller diameters yield shorter deformation zones and larger biting angles.
To determine the effect of the roller surface temperature on the percentage elongation of the battery electrodes, a calendering experiment was conducted using roller 4 (calender 3). The roller surface temperature was heated to 50 °C and 80 °C for calendering, and the results were compared with the data obtained at room temperature.
