We have developed a method which is adaptable and straightforward for the production of a negative electrode material based on Si/carbon nanotube (Si/CNTs) composite for Li-ion batteries.
Besides, when serving as negative electrode materials for LIBs, Si nanotubes exhibit better Li storage performance than Si nanoparticles and Si nanowires, showing a capacity of 3044 mAh g –1 at 0.20 A g –1 and 1033 mAh g –1 after 1000 cycles at 1 A g –1. This work provides a controllable approach for the synthesis of Si nanomaterials for LIBs.
Silicon (Si) is a promising negative electrode material for lithium-ion batteries (LIBs), but the poor cycling stability hinders their practical application. Developing favorable Si nanomaterials i...
Pitch-based carbon/nano-silicon composites are proposed as a high performance and realistic electrode material of Li-ion battery anodes. Composites are prepared in a simple way by the pyrolysis under argon atmosphere of silicon nanoparticles, obtained by a laser pyrolysis technique, and a low cost carbon source: petroleum pitch.
However, ASSBs are detrimentally affected by a limited rate capability and inadequate performance at high currents. To circumvent these issues, here we propose the use of Nb 1.60 Ti 0.32 W 0.08 O 5-δ (NTWO) as negative electrode active material.
The performance of the synthesized composite as an active negative electrode material in Li ion battery has been studied. It has been shown through SEM as well as impedance analyses that the enhancement of charge transfer resistance, after 100 cycles, becomes limited due to the presence of CNT network in the Si-decorated CNT composite.
