To enhance the electrochemical performance of nickel oxide as anode materials for lithium ion batteries, NiO/carbon aerogel microspheres with a plum-pudding structure were designed and prepared by a sol-gel technique followed by two calcination processes under different atmospheres. Carbon aerogel microspheres (pudding) can act as a buffering and conductive matrix to enhance the structural stability and conductivity of the embedded NiO particles (plums), which are quite advantageous to the cycling performance and rate capability. Consequently, NiO/carbon aerogel microspheres with a plum-pudding structure deliver an initial charge capacity of 808 mAh g−1 and a reversible capacity retention of 85% after 100 cycles. The enhancement in electrochemical performance relative to pure NiO microspheres suggests that the design of a plum-pudding structure is quite effective.

ABSTRACTAn efficient microwave-assisted polyol (MP) approach is report to prepare SnO2/graphene hybrid as an anode material for lithium ion batteries. The key factor to this MP method is to start with uniform graphene oxide (GO) suspension, in which a large amount of surface oxygenate groups ensures homogeneous distribution of the SnO2 nanoparticles onto the GO sheets under the microwave irradiation. The period for the microwave heating only takes 10 min. The obtained SnO2/graphene hybrid anode possesses a reversible capacity of 967 mAh g-1 at 0.1 C and a high Coulombic efficiency of 80.5% at the first cycle. The cycling performance and the rate capability of the hybrid anode are enhanced in comparison with that of the bare graphene anode. This improvement of electrochemical performance can be attributed to the formation of a 3-dimensional framework. Accordingly, this study provides an economical MP route for the fabrication of SnO2/graphene hybrid as an anode material for high-performance Li-ion batteries.
