Na-ion batteries (NIBs) have attracted much attention as a next generation power source for a large scale energy storage system, because of bio-abundant Na resource and its chemistry similar to Li-ion batteries (LIBs). Electrochemical performances of NIBs are highly dependent on their active electrode materials; therefore, development of advanced active electrode materials is indispensable for developing high performance NIBs. In this study, nanoporous pyropolymers (N-PPs) were fabricated from pine cones by simple heating at 800 ℃ in the presence of potassium hydroxide and used as an anode material for Na ion storage. N-PPs showed significantly high specific capacity, rate capabilities and long-term cycle lives as an anode for NIBs. |
