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
