Abstract
Abstract Porous carbon spheres (PCSs) with high surface area were fabricated by the reaction of D-Glucose monohydrate precursor with sodium molybdate dihydrate (Na 2 MoO 4 ·2H 2 O) via a facile hydrothermal method followed by carbonization and aqueous ammonia solution (NH 3 ·H 2 O) treatment. The as-prepared PCSs exhibit a highly developed porous structure with a large specific surface area and show an excellent electrochemical performance as anode material of sodium-ion batteries (SIBs). A reversible capacity of 249.9 mA h g −1 after 50 cycles at a current density of 50 mA g −1 and a long cycling life at a high current density of 500 mA g −1 are achieved. The excellent cycling performance and high capacity make the PCSs a promising candidate for long cycling SIBs.
