We report a facile chemical vapor deposition (CVD) method to grow silicon/carbon (Si/C) microrods on the surface of commercial graphite microspheres (GMs) prepare Si/C/GM composite materials as Li-ion battery anodes. Dimethyldichlorosilane and toluene were used Si C precursors, respectively. The CVD temperature time, well mechanism growth investigated. samples characterized by using X-ray diffraction, thermogravimetric analysis, photoelectron spectroscopy, Raman scanning electron microscopy,...
In the field of solid-state lithium metal batteries (SSLMBs), constructing vertically heterostructured poly(ethylene oxide) (PEO)-based solid electrolytes is an effective method to realize their tight contact with cathodes and Li anodes at same time. Succinonitrile (SN) has been widely used in PEO-based improve interface cathodes, enhance ionic conductivities, obtain a high electrochemical stability window PEO, but its application still hindered by intrinsic instability anodes, which results...
The yolk–shell hollow structure of transition metal oxides has many applications in lithium-ion batteries and catalysis. However, it is still a big challenge to fabricate uniform microspheres with the yolk bishell for mixed their supported or embedded forms carbon superior lithium storage properties. Here we report new approach synthesis manganese cobalt iron oxides/carbon (MnxCo1–xFe2O4 (0 ≤ x 1)) through carbonization Mn2+Co2+Fe3+/carbonaceous N2, which can be directly applied as...
We report the preparation and characterization of amorphous silicon–carbon (Si–C) nanospheres as anode materials in Li-ion batteries. These were synthesized by a chemical vapor deposition at 900 °C using methyltrichlorosilane (CH3SiCl3) both Si C precursor, which is cheap byproduct organosilane industry. The samples characterized X-ray diffraction, transmission electron microscopy, scanning nitrogen adsorption, thermal gravimetric analysis, Raman spectroscopy, photoelectron spectroscopy. It...
To mitigate the massive volume expansion of Si-based anode during charge/discharge cycles, we synthesized a superstructure [email protected]–NC composite via carbonization zeolite imidazolate frameworks incorporated with Si nanoparticles. The is comprised Si-nanoparticle core and N-doped/Co-incorporated carbon shell, there void space between shell. When using as material for LIBs, displayed super performance capacity 191.6/191.4 mA h g−1 coulombic efficiency 100.1% at 1000 after 3000 loss...
To improve the initial Coulombic efficiency, cycling stability, and rate performance of Li-rich Mn-based Li1.2Mn0.54Ni0.13Co0.13O2 cathode, combination LiMn1.4Ni0.5Mo0.1O4 coating with Mo doping has been successfully carried out by sol–gel method subsequent dip-dry process. This strategy buffers electrodes from corrosion electrolyte enhances lattice parameter, which could inhibit oxygen release maintain structural thus improving cycle stability capability. After modification, discharge...
We report the growth of linked silicon/carbon (Si/C) nanospheres on Cu substrate as an integrated anode for Li-ion batteries. The Si/C were synthesized by a catalytic chemical vapor deposition (CCVD) current collector using methyltrichlorosilane precursor, cheap by-product organosilane industry. samples characterized X-ray diffraction, transmission electron microscopy, scanning thermal gravimetry, Raman spectroscopy, nitrogen adsorption, inductively coupled plasma optical emission...
With the increasing demand for high energy density and rapid charging performance, Li-rich materials have been up coming cathodes next-generation lithium-ion batteries. However, because of oxygen evolution structural instability, commercialization is extremely retarded by their poor electrochemical performances. In this work, Li-deficient Li0.3NbO2 (Nb0.62Li0.15)TiO3 are applied to functionalize surface Li1.2Mn0.54Ni0.13Co0.13O2, aiming suppress increase stability in LIBs. addition, a fast...
A novel low-cost synthesis route of porous Si materials is developed via ferrite-assisted chemical etching instead noble metal-assisted etching. The obtained Si/C and Si/C/ferrite used as anodes in Li-ion batteries exhibit good electrochemical performance.
