Iron and silicon oxide doped/PAN-based carbon nanofibers as free-standing anode material for Li-ion batteries.

The advanced rechargeable batteries have been upgraded by the production of free-standing electrodes through electrospinning technology. This study aimed to introduce a novel hybrid composition to design a free-standing carbon nanofiber (CNF) based anode by the addition of iron acetylacetonate Fe(AcAc) as active material and TEOS(tetraethoxysilane)/APTES(aminopropyl triethoxysilane) as an additive for Li-ion batteries. Polyacrylonitrile(PAN) was used as the polymer matrix in the spin dope, and the inclusion of Fe(AcAc) and TEOS/APTES resulted in compositional change, producing iron oxide and silica nanoparticles throughout the matrix.

Surface modification of tin oxide through reduced graphene oxide as a highly efficient cathode material for magnesium-ion batteries.

Among post-lithium ion technologies, magnesium-ion batteries (MIBs) are receiving great concern in recent years. However, MIBs are mainly restrained by the lack of cathode materials, which may accommodate the fast diffusion kinetics of Mg ions. To overcome this problem, herein we attempt to synthesize a reduced graphene oxide (rGO) encapsulated tin oxide (SnO) nanoparticles composites through an electrostatic-interaction-induced-self-assembly approach at low temperature.
