Bio-derived porous carbon has been synthesized from the seeds of Litchi chinensis (lychee) by a simple,economic and environment-friendly approach. The material is characterized by different physical characterization techniques, the XRD and Raman spectra revealed the mixed amorphous and graphitic nature of the carbon whereas FE-SEM, HRTEM, and BET analysis proved its highly porous nature. While testing its application in battery against sodium metal it provided a superficial storage and transport path for sodium-ions. The sodium-ion adsorption mechanism has been well studied by ex-situ experimental techniques. The biocarbon anode further showed an excellent rate capability and a superior electrochemical reversible specific capacity of ~146 mAh g

The construction and demonstration of SIB coin cell with NVP cathode and biocarbon anode open up the possibility of its applications in future.
