“…In addition, their high electrical conductivity and large electrolyte/electrode contact area are favorable to the reversible insertion and extraction of Na + , resulting in excellent and stable electrochemical performance [23]. Many types of biomass such as bamboo [24], water hyacinths [25], waste tea [26], corn stalk [27], wood [28,29], lotus [30], kelp [31], and human hair [32] have been investigated as a precursor for producing porous carbon materials for various energy storage devices; however, it is still a challenge to prepare high-performance porous carbon from a cost-efficient resource.…”
