A composite anode material of SnO2/graphite(GT)/carbon nanotube(CNT) for lithium-ion batteries was prepared by ball milling. It was observed that SnO2 particles were homogeneously embedded into the buffering matrix of graphite particles. This composite anode material showed an increased initial coulombic efficiencies of 56% in the first cycle, and after 25 charge–discharge cycles, a reversible capacity of 431 mAh/g was obtained, much higher than 282 mAh/g of SnO2/GT composite and 177 mAh/g of pure SnO2. The improvement in the electrochemical properties of the composite anode materials was mainly attributed to good electric conductivity of the CNT network and the excellent resiliency.

Silicon/carbon (Si/C) composite anode materials are successfully synthesized by mechanical ball milling followed by pyrolysis method. The structure and morphology of the composite are characterized by X-ray diffraction and scanning electron microscopy and transmission electron microscope, respectively. The results show that the composite is composed of Si, flake graphite, and phenolic resin-pyrolyzed carbon, and Si and flake graphite are enwrapped by phenolic resin-pyrolyzed carbon, which can provide not only a good buffering matrix but also a conductive network. The Si/C composite also shows good electrochemical stability, in which the composite anode material exhibits a high initial charge capacity of 805.3 mAh g−1at 100 mA g−1and it can still deliver a high charge capacity of 791.7 mAh g−1when the current density increases to 500 mA g−1. The results indicate that it could be used as a promising anode material for lithium ion batteries.

Lithium ion (Li-ion) batteries have been widely applied to portable electronic devices and hybrid vehicles. In order to further enhance performance, the search for advanced anode materials to meet the growing demand for high-performance Li-ion batteries is significant. Fe3C as an anode material can contribute more capacity than its theoretical one due to the pseudocapacity on the interface. However, the traditional synthetic methods need harsh conditions, such as high temperature and hazardous and expensive chemical precursors. In this study, a graphitic carbon encapsulated Fe/Fe3C (denoted as Fe/Fe3C@GC) composite was synthesized as an anode active material for high-performance lithium ion batteries by a simple and cost-effective approach through co-pyrolysis of biomass and iron precursor. The graphitic carbon shell formed by the carbonization of sawdust can improve the electrical conductivity and accommodate volume expansion during discharging. The porous microstructure of the shell can also provide increased active sites for the redox reactions. The in-situ-formed Fe/Fe3C nanoparticles show pseudocapacitive behavior that increases the capacity. The composite exhibits a high reversible capacity and excellent rate performance. The composite delivered a high initial discharge capacity of 1027 mAh g−1 at 45 mA g−1 and maintained a reversible capacity of 302 mAh g−1 at 200 mA g−1 after 200 cycles. Even at the high current density of 5000 mA g−1, the Fe/Fe3C@GC cell also shows a stable cycling performance. Therefore, Fe/Fe3C@GC composite is considered as one of the potential anode materials for lithium ion batteries.

Abstract Porous structures in anode materials are of importance to accommodate volume dilation of active matters. In the present case, a carbon nanoporous framework is hydrothermally synthesized from glucose in the presence of graphene oxide (GO), together with in situ active Fe3O4 nanoparticles within it. The composite anode material has outstanding electrochemical performance, including high specific capacity, excellent cyclic stability and superior rate capability. The specific capacity stays at 830.8 mAhg−1 after 200 cycles at 1 A/g, equivalent to a high capacity retention of 88.7%. The findings provide valuable clues to tailor morphology of hydrothermally carbonized glucose for advanced composite anode materials of lithium-ion batteries.
