摘      要：Four types of sustainable sodium carboxylate- derived materials are investigated as novel electrodes with high performance for lithium-ion batteries. Benefiting from the porous morphology provided by their intermolecular in- teractions, increasing capacity, excellent cycle stability and superior rate performance are observed for the sodium car- boxylate-derived materials. The sodium oxalate （SO） electro- des displayed an increasing discharging capacity at a current density of 50 mA g-1 with maximum values of 242.9 mA h g-1 for SO-631 and 373.9 mA h g-1 for SO-541 during the 100th cycle. In addition, the SO-541, SC-541 （sodium citrate）, ST- 541 （sodium tartrate） and SP-541 （sodium pyromellitate） electrode materials displayed high initial capacities of 619.6-392.3, 403.7 and 278.1 mA h g-1, respectively, with capacity retentions of 179%, 148%, 173% and 108%, respectively, after 200 cycles at 50 mA g-1. Even at a high current density of 2,000 mA g-1, the capacities remain 157.6, 131.3, 146.6 and 137.0mAhg-1, respectively. With these superior electro- chemical properties, the sodium carboxylate-derived materials could be considered as promising organic electrode materials for large-scale sustainable lithium-ion batteries.
