3-dimensional carbon nanotube for Li-ion battery anode

摘要: Abstract Carbon nanotubes, in different forms and architectures, have demonstrated good promise as electrode material for Li-ion batteries, owing to large surface area, shorter Li-conduction distance high electrical conductivity. However, practical application of such batteries demands higher volumetric capacity, which is otherwise low most nanomaterials, used electrodes. In order address this urgent issue, we developed a novel 3-dimensional (3D) anode, based on multiwall carbon nanotubes (MWCNTs), batteries. The unique 3D design the allowed much solid loading active anode material, MWCNTs case resulted more amount Li + ion intake comparison those conventional 2D Cu current collector. Though one was offer 50% compared its counterpart, ability deliver by geometrical modification, presented. Furthermore, deposition amorphous Si (a-Si) layer (a-Si/MWCNTs hybrid structure) offered enhancement electrochemical response. Correlation between performances structural properties anodes highlights possible charge transfer mechanism.
