Hollow carbon nanospheres/silicon/alumina core-shell film as an anode for lithium-ion batteries
Hollow carbon nanospheres/silicon/alumina (CNS/Si/Al₂O₃) core-shell films obtained by the deposition of Si and Al₂O₃ on hollow CNS interconnected films are used as the anode materials for lithium-ion batteries. The hollow CNS film acts as a three dimensional conductive substrate and provides void space for silicon volume expansion during electrochemical cycling. The Al2O3 thin layer is benefici...
متن کاملThe Anode Challenge for Lithium‐Ion Batteries: A Mechanochemically Synthesized Sn–Fe–C Composite Anode Surpasses Graphitic Carbon
Carbon-based anodes are the key limiting factor in increasing the volumetric capacity of lithium-ion batteries. Tin-based composites are one alternative approach. Nanosized Sn-Fe-C anode materials are mechanochemically synthesized by reducing SnO with Ti in the presence of carbon. The optimum synthesis conditions are found to be 1:0.25:10 for initial ratio of SnO, Ti, and graphite with a total ...
متن کاملSynthesis of tin-encapsulated spherical hollow carbon for anode material in lithium secondary batteries.
The tributylphenyltin (TBPT)-encapsulated resorcinol (R)-formaldehyde (F) sol was prepared inside the micelles of cetyltrimethylammonium bromide (CTAB). This core-shell-type sol was polymerized and further carbonized to obtain nanosized Sn-encapsulated spherical hollow carbon. The size of spherical hollow carbon and Sn metal particles was controllable by changing the R/CTAB or TBPT/CTAB mole ra...
متن کاملSynthesis of Hard Carbon- Silicon Nanocomposite as Anode Active Material for Lithium-Ion Batteries
In this research, using phenolic resin as the precursor of carbon and various amounts of ethylene glycol as a pore former, porous samples of hard carbon were synthesized. Samples were characterized by x-ray diffraction (XRD) and N2 adsorption-desorption methods. Broad diffraction peaks represent the amorphous structure of samples. Moreover, the gas adsorption-desorption curves showed that the a...
متن کاملOne-pot galvanic formation of ultrathin-shell Sn/CoO(x) nanohollows as high performance anode materials in lithium ion batteries.
The thermolysis of a heterobimetallic Sn-Co organometallic precursor resulted in the formation of hollow Sn/CoOx nanomaterials through galvanic reaction between metal species. The Sn/CoOx nanohollows with 6.1 nm diameter and ~1.5 nm shell thickness showed excellent lithium storage capacity of up to 857 mA h g(-1) after 30 cycles.
