Boosting the Lithium Storage of Tin Dioxide Nanotubes by MXene Inks as Conductive Binder

Ti3C2Tx MXene inks (MIK) with highly concentrated and viscoelastic skeleton were developed as conductive binder to fabricate a SnO2 nanotube (NT) electrode. Thus, the unique design renders SnO2 [email protected] electrode a great capacity of 704.3 mAh g−1 at 50 mA g−1 and long-term cyclability. These results support that MIK can be used as an excellent conductive binder to improve the electrochemical performance of SnO2 NT. Highly concentrated Ti3C2Tx MXene inks were developed as conductive binder to improve the cyclability and rate performance of the SnO2 nanotube electrodes.
