Paper Title:
Net-Like ZnO/Carbon–Aerogel Composite as Anode Material for Ni-Zn Secondary Battery
  Abstract

Nanosized ZnO particles were prepared by a facile homogeneous precipitation method. Resorcinol-formaldehyde sol with addition of the ZnO particles was carbonized at 700 °C for 1.5 h to prepare ZnO/carbon-aerogel composite. TEM investigation shows that ZnO particles were em-bedded in 3-dimensional net-like carbon and covered uniformly by amorphous carbon coating. Compared with ZnO, the ZnO/carbon-aerogel composite showed better cycling stability, higher discharge capacity and lower charge-transfer resistance. The discharge capacity delivered by the ZnO/carbon-aerogel composite remained above 550 mAh g-1 during 40 cycles with little capacity loss. The enhanced electrochemical performances were mainly ascribed to the effects of the net-like structure of amorphous carbon, which uniformly surrounded the ZnO particles to guarantee good contact and acted as a skeleton to alleviate the shape change and dendrite growth of zinc electrode.
