4. Conclusions
- (1)
- This sintering method can be easily applied to large-scale production.
- (2)
- The CFSCC is technically suitable for Si-based paste electrodes, which are inexpensive, and the paste-like electrode is commonly used in industrial production.
- (3)
- Through the electrochemical test and SEM images, the CFSCC shows the ability to constrain the Si volume change and had better electric performance. The CFSCC with a powder size of 75–100 μm performed best in this study. Compared with the flat current collector, the capacitance of the electrodes with CFSCC remained as high as 92.2% of its second cycle after 40 cycles, whereas that of electrodes with the flat current collector only remained at 51.1%.
