Ni 2 P Nanosheets on Carbon Cloth: An Efficient Flexible Electrode for Sodium-Ion Batteries

Transition-metal phosphides have been increasingly investigated because of their high theoretical specific capacity and low potential for sodium storage. Herein, we describe the development of Ni P nanosheets on carbon cloth (Ni P Ns/CC), which behaves as a flexible 3D anode for sodium-ion batteries...

Description
Summary:Transition-metal phosphides have been increasingly investigated because of their high theoretical specific capacity and low potential for sodium storage. Herein, we describe the development of Ni P nanosheets on carbon cloth (Ni P Ns/CC), which behaves as a flexible 3D anode for sodium-ion batteries. Such a Ni P Ns/CC delivers a high capacity of 399 mA h g at 0.2 A g . At 2 A g , it still delivers 72 mA h g even after 1000 cycles. The impressive performance is attributed to such a self-supported structure. Moreover, a possible conversion reaction mechanism is also carefully revealed.
