Organic sodium terephthalate@graphene hybrid anode materials for sodium-ion batteries?
RSC Advances Pub Date: 2016-06-08 DOI: 10.1039/C6RA11809G
Abstract
In the search for high-performance electrodes for sodium-ion battery applications, there is a high demand for organic materials with satisfactory electrochemical performances, especially high rate capabilities. Herein, we report an organic based composite, sodium terephthalate@graphene (Na2TP@GE) hybrid synthesized via freeze-drying technique. This material shows an interconnected, multi-channelled monolith structure, which resulted in outstanding rate capability for sodium storage. This hybrid material demonstrated a high reversible capacity of 268.9 mA h g?1 and prolonged cyclability with capacity retention of 77.3% over 500 cycles.
