The future development of large-scale energy store systems requires Li-ion batteries (LIBs) with not only an outstanding electrochemical performance but also sustainability and cost-effectiveness. Herein, unique carbon-sheets (CSs) with rich porosity and high graphitization have been synthesized from sugarcane-stalk for LIBs application. These derived CSs exhibit a superior electrochemical behavior to commercial graphite. Moreover, the performance of CSs can be further upgraded by growing MnO nanoparticles to form a synergetic MnO-C hybrid. As a result, the MnO-C hybrid shows a high capacity, excellent rate capability (354mA h g(-1) at 3 A g(-1)), and superior cycling performance (814 mA h g(-1) at 0.2 A g(-1) after 400 cycles).
