Synthesis of Fe3O4/C composite microspheres for a high performance lithium-ion battery anode

Graphene/acid assisted facile synthesis of structure-tuned Fe3O4 and graphene composites as anode materials for lithium ion batteries

“…based conducting matrixes to form hybrid composites resulting in the potential multiple advantages including: shortened Li + ions diffusion path lengths; enlarged contact area between electrode and electrolyte; improved electronic conductivity; and alleviated mechanical stress during Li + ion insertion/ extraction [11][12][13][14][15].…”

Carbothermal Synthesis of Nitrogen-Doped Graphene Composites for Energy Conversion and Storage Devices

“…In order to maintain the electrode integrity, some strategies including coating with carbonaceous materials (He C. et al, 2013 ) and fabricating nanostructure (Behera, 2011 ; Lim et al, 2012 ; Zeng et al, 2014 ) have been widely reported. Nevertheless, to realize these improvements, many in situ synthetic methods, such as sol-gel polymerization (Jung et al, 2013 ), solvothermal or hydrothermal method (Yuan et al, 2011 ; Zhu et al, 2011a ), electrospinning (Wang et al, 2008 ) and chemical vapor deposition (Zhu et al, 2013 ) have been utilized, but they are short for large-scale application. What' more, carbonaceous materials especially graphene, which received worldwide attention owing to its outstanding properties, shows superior performances in high-performance lithium-ion batteries due to their good conductivity and large surface areas (Behera, 2011 ; Yan et al, 2014 ).…”

Chemical vapor deposition prepared bi-morphological carbon-coated Fe3O4 composites as anode materials for lithium-ion batteries

“…Carbon coating can not only increase the electrical conductivity and accommodate the volume change of iron oxides during cycling [17e20], but also acts as barrier to prevent the aggregation of the metallic clusters during the repeated conversion reaction between the iron oxide and the metallic grains. Carbon coating can be prepared by in situ pyrolysis of organic components [21,22]. However, longtime thermal treatment (2e12 h) for carbon pyrolysis at temperature range of 360e700 C is reported [10,22e25].…”
