Loading Fe3O4 nanoparticles on paper-derived carbon scaffold toward advanced lithium–sulfur batteries

Fe3O4@ZIF-8: magnetically recoverable catalysts by loading Fe3O4 nanoparticles inside a zinc imidazolate framework.

A simple methodology for encapsulating ca. 10 nm-sized superparamagnetic Fe3O4 nanoparticles in zeolitic imidazolate frameworks (ZIF-8) crystals was developed. The corresponding Fe3O4@ZIF-8 heterostructured material exhibits bifunctional properties with both high magnetization (Fe3O4) and high thermal stability, large specific surface, and catalytic properties (ZIF-8). The Fe3O4@ZIF-8 catalyst ...

Carbon scaffold structured silicon anodes for lithium-ion batteries

A unique methodology of fabricating Si anodes for lithium-ion batteries with porous carbon scaffold structure is reported. Such carbon scaffold Si anodes are fabricated via carbonization of porous Si-PVdF precursors which are directly deposited on the current collector. Unlike the conventional slurry casting method, binder and conductive additives are not used in the preparation of the carbon s...

Three-Dimensional Carbon Nanostructures for Advanced Lithium-Ion Batteries

Carbon nanostructural materials have gained the spotlight as promising anode materials for energy storage; they exhibit unique physico-chemical properties such as large surface area, short Li+ ion diffusion length, and high electrical conductivity, in addition to their long-term stability. However, carbon-nanostructured materials have issues with low areal and volumetric densities for the pract...

SU8 Derived Glassy Carbon for Lithium Ion Batteries

Glassy carbon (GC) is an amorphous yet sp rich allotrope of carbon that has received a lot of attention as an electrode material in Li ion batteries. In this contribution we explore the microstructural, thermal and mechanical properties of GC derived from the pyrolysis of lithographically patterned SU8, which is the most common precursor polymer in CMEMS (carbon microelectromechanical systems)....
