| description | Lithium iron phosphate (LiFePO4) batteries represent a critical energy storage solution in various applications, necessitating advancements in their performance. In this investigation, we employ an innovative hydrothermal method to introduce an organic carbon coating onto LiFePO4 particles. Our study harnesses glucose as the carbon source, a readily available and cost-effective material. Through a controlled synthesis process, a uniform carbon layer is formed on LiFePO4particles, enhancing both their electrical conductivity and stability. This novel approach effectively curbs undesirable side reactions and facilitates improved electrochemical performance. Our comprehensive characterization utilizing SEM, XRD, and electrochemical tests underscores the significant enhancements achieved. Specifically, SEM analysis reveals smaller and more uniform particle sizes, correlating with increased contact area and improved electrochemical interfaces. XRD patterns validate the maintenance of the desired crystal structure even with the incorporation of carbon. The specific capacity results underscore the positive influence of our approach, as the sample with 10 wt% glucose exhibits remarkable enhancements, suggesting optimized electronic conductivity and Li+ diffusion kinetics. Moreover, our investigation into rate capability illuminates the sample's robust performance under varying current densities. Crucially, our study introduces a noteworthy advancement in LiFePO4 battery technology. By combining the hydrothermal method with glucose as a carbon source, we achieve a refined balance between conductivity and stability. This approach not only offers a more coherent synthesis process but also emphasizes the novel contribution of our work to the field of energy storage. Overall, our findings signify a substantial step towards enhancing LiFePO4-based batteries for emerging energy demands. |
