            Pineapple leaf fiber (PALF) holds promise as an affordable carbon source for producing high-quality graphitic carbon material due to its abundance and rich content of crystalline cellulose. In this study, PALF was utilized to create activated porous carbon material for lithium batteries. By employing a practical hydrothermal process followed by carbonization with a chemical activation method, a three-dimensional porous carbon structure with interconnected open channels and a high specific surface area was achieved.

            The resulting activated porous carbon material demonstrated excellent electrochemical performance when employed as an electrode in lithium batteries. It exhibited a high initial charge-discharge capacity and maintained stability during cycling. Moreover, the carbon material displayed high coulombic efficiency, indicating efficient charge transfer during battery operation. These findings highlight the potential of PALF as a carbon precursor for producing activated porous carbon materials with desirable characteristics for lithium battery applications. This study contributes to the exploration of sustainable and cost-effective materials for energy storage systems.
