Article Description

Organic tetralithium salts of 2,5-dihydroxyterephthalic acid (Li CHO) with the morphologies of bulk, nanoparticles, and nanosheets have been investigated as the active materials of either positive or negative electrode of rechargeable lithium-ion batteries. It is demonstrated that, in the electrolyte of LiPF dissolved in ethylene carbonate (EC) and dimethyl carbonate (DMC), reversible two-Li-ion electrochemical reactions are taking place with redox Li CHO/LiC HO at ∼2.6 V for a positive electrode and LiCHO/LiC HO at ∼0.8 V for a negative electrode, respectively. In the observed system, the electrochemical performance of high to low order is nanosheets > nanoparticles > bulk. Remarkably, Li CHO nanosheets show the discharge capacities of 223 and 145 mAh g at 0.1 and 5 C rates, respectively. A capacity retention of 95% is sustained after 50 cycles at 0.1 C rate charge/discharge and room temperature. Moreover, charging the symmetrical cells with LiCHO nanosheets as the initial active materials of both positive and negative electrodes produces all-organic LIBs with an average operation voltage of 1.8 V and an energy density of about 130 Wh kg, enlightening the design and application of organic Li-reservoir compounds with nanostructures for all organic LIBs. © 2013 American Chemical Society.
