Abstract: Porous carbon has received great attention for electrochemical energy storage devices. In this study, we proposed a novel and scalable method to fabricate porous carbon, which contained macro and mesopores, from sustainable biomass raw material of cotton cellulose. A MgO template, which acted as a pore creator, was incorporated into the cellulose-derived carbon by absorbing a Mg(NO3)(2) solution into cellulose fibers with subsequent drying and carbonization processes. After removing the MgO template by acid leaching, porous carbon was produced with a specific surface area as high as 1260 m(2) g(-1). The sample showed attractive electrochemical performances as the anode material for Li ion batteries (LIBs). The carbon anode delivered a high reversible capacity of 793 mA h g(-1) at a current density of 0.5 A g(-1) after 500 cycles. The carbon anode also showed a high-rate capability and a capacity of 355 mA h g(-1) can be obtained at a current density of 4 A g(-1). A widespread comparison with the literature also showed that the cotton-derived porous carbon was among the most promising carbon-based anodes for LIBs.
