Bithiophene dicarboxylate as an efficient organic anode material for sodium-ion batteries

In this study, new carboxylates are synthesized for sodium-ion batteries. The bithiophene-based anode material BT demonstrates a high reversible capacity of 201 mA h g and excellent durability. BT retains 99.1% capacity after 400 cycles at 0.2C and 90.1% capacity after 1500 cycles at 2C, showing sup...

Zusammenfassung:	In this study, new carboxylates are synthesized for sodium-ion batteries. The bithiophene-based anode material BT demonstrates a high reversible capacity of 201 mA h g and excellent durability. BT retains 99.1% capacity after 400 cycles at 0.2C and 90.1% capacity after 1500 cycles at 2C, showing superior conductivity and stability.
