Abstract

A Na-ion battery with high rate capability and long cycling life consists of high mass loading self-standing NaTi2(PO4)3 anode and Na3V2(PO4)3 cathode.

Highlights

  • Portable and wearable electronic devices with high exibility have achieved increasing popularity and a booming market in recent years for a wide range of applications such as roll-up displays, implantable biomedical devices and comfortable electronic skins for health monitoring.[1,2,3] To meet the energy demands of these advanced electronic devices, considerable efforts have been dedicated to the development of exible energy storage systems with high electrochemical performance

  • On the basis of the TGA results (Fig. S1†), about 23.5 and 27.4 wt% carbon phases were present in NTP/carbon nanotube fabrics (CNFs) and NVP/CNFs, respectively, including CNFs and amorphous carbon created by carbonization of the starting materials

  • The analyses showed that the charge transfer resistance (Rct) of NTP/CNFs and NVP/CNFs decreased slightly from 145 and 120 U before the formation cycles to 104 and 82 U a er the formation cycles, respectively
