Abstract

Designing an anode with a low-cost and simple preparation method is the key to developing the lithium ion battery. Here, ZnNCN nanoparticles are synthesized by one-step calcination of the mixture of melamine and zinc nitrate. By adjusting the reaction temperature, the pure ZnNCN with good crystalline character is obtained. The conversion-type mechanism of ZnNCN is proved by ex situ X-ray diffraction and electrochemical curves. More importantly, ZnNCN exhibits a high discharging capacity (405 mAh g–1 at 0.1 A g–1), an excellent rate property (140 mAh g–1 at 3 A g–1), and a long cyclic life (capacity fading per cycle of 0.025% during 700 cycles at 1.0 A g–1). Also, this work provides a new approach to prepare metal carbodiimides.
