Most of the carbon materials derived from biomass exhibit specific capacity in the range of 200–300 mA·h·g −1 at a current density of 50 mA·g −1 in sodium-ion batteries [214,215,216]. In particular, a coir pith waste derived carbon (CPC) electrode demonstrated a capacity of 220 mA·h·g −1 up to 300 cycles with negligible capacity …
