effect of temperature on electrical efficiency coconut shell

Introduction

The effect of temperature on the electrical efficiency of coconut shell-derived char is a critical area of research, particularly for applications in energy storage and electrode fabrication. This synthesis aims to consolidate findings from multiple studies to provide a clear understanding of how varying carbonization temperatures impact the electrical properties of coconut shell char.

Key Insights

Improvement in Electrical Conductivity with Increased Temperature:
- The electrical properties of coconut shell char significantly improve as the carbonization temperature increases. Specifically, the electrical conductivity of the char increases from 3.52 x10^-8 S/cm at 600°C to 6.78 x10^-2 S/cm at 1150°C.
Changes in Physical and Chemical Properties:
- Higher carbonization temperatures lead to a decrease in moisture content and percentage yield, while the volatile matter and fixed carbon percentage change significantly. These changes contribute to the improved electrical properties.
Morphological and Structural Enhancements:
- The morphological characterization shows that higher temperatures result in the development of pores in the char, which are suitable for adsorption and movement of electrolyte ions, thereby reducing diffusion resistance. Additionally, X-ray diffractometer analysis indicates improved graphitic properties at higher temperatures, which are beneficial for electrode fabrication.

Conclusion

Increasing the carbonization temperature of coconut shell char enhances its electrical efficiency. This improvement is attributed to changes in the physical and chemical properties, as well as the development of a more porous structure and improved graphitic properties. These findings suggest that higher carbonization temperatures are favorable for applications requiring high electrical conductivity, such as in electrode materials.
