Lithium-ion batteries (LIBs) are in great demand as energy storage systems applied in wide range of electronic devices. However, currently used commercial anodes have a limited capacity of 372 mAh g -1. Therefore, development of novel carbon materials for high performance electrodes is of high interest. Recently, biomasses have attracted much attention as electrode materials for LIBs due to their low cost and environmental sustainability. In this research, a nitrogen-doped porous biomass graphene material was prepared from date seeds as an organic matter through carbonization and chemical activation.
