Manufacture of Cnt Reinforced Polymer Composites Using Nanofibers Containing Cnt
Carbon nanotubes (CNTs), discovered by Japanese scientist Sumio Iijima, have outstanding material properties such as mechanical, thermal, electrical, and magnetic properties. For example, CNTs are not only lighter than common irons, but also 100 times stronger than the irons. However, CNTs are so tiny, that is, surface area per volume is relatively large. Consequently, they tend to agglomerate....
متن کاملCore-shell CNT-Ni-Si nanowires as high performance anode material in lithium ion battery
Core-shell carbon nanotube (CNT)-Si heterogeneous nanowires have been identified as one of the most promising candidates for future anode materials in lithium ion batteries. However, stress in these nanostructures, is the long-existing bottleneck, rendering severe fading of the capacities and even failure of the batteries. We prove that the interfaces between CNT cores and Si shells play a crit...
متن کاملElectrochemical Properties of Chemically Processed SiOx as Coating Material in Lithium-Ion Batteries with Si Anode
A SiO x coating material for Si anode in lithium-ion battery was processed by using SiCl4 and ethylene glycol. The produced SiO x particles after heat treatment at 725°C for 1 h were porous and irregularly shaped with amorphous structure. Pitch carbon added to SiO x was found to strongly affect solid electrolyte interphase stabilization and cyclic stability. When mixed with an optimal amount of...
متن کاملElectrochemical Properties of Si-Ge Heterostructures as an Anode Material for Lithium Ion Batteries
Among them, Si is the most promising candidate due to its high theoretical specifi c capacity (4200 mAh g −1 ). [ 5 ] However, its practical use in commercial application is limited by both poor cycle retention, caused by high volume change during cycling, and poor rate capabilities, due to its inherent low electron conductivity and ion diffusivity. There are two general approaches to overcome ...
متن کاملFacile synthesis and electrochemical performances of hollow graphene spheres as anode material for lithium-ion batteries
UNLABELLED The hollow graphene oxide spheres have been successfully fabricated from graphene oxide nanosheets utilizing a water-in-oil emulsion technique, which were prepared from natural flake graphite by oxidation and ultrasonic treatment. The hollow graphene oxide spheres were reduced to hollow graphene spheres at 500°C for 3 h under an atmosphere of Ar(95%)/H2(5%). The first reversible spec...
