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.
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.
The silicon-based negative electrode materials prepared through alloying exhibit significantly enhanced electrode conductivity and rate performance, demonstrating excellent electrochemical lithium storage capability. Ren employed the magnesium thermal reduction method to prepare mesoporous Si-based nanoparticles doped with Zn .
Si/CNT nano-network coated on a copper substrate served as the negative electrode in the Li-ion battery. Li foil was used as the counter electrode, and polypropylene served as the separator between the negative and positive electrodes. The electrolyte was 1 M LiPF6 in ethylene carbonate (EC)/dimethyl carbonate (DMC) (1:1 by volume).
Analysis of the electrochemical properties of the synthesized Cu-Si nanocomposite reveals great promise for use as a lithium-ion battery anode. Table 3 summarizes recent advancements in the preparation of nano-silicon and its composites using molten salt electrolysis and various established technologies.
For Si@C anode materials of lithium-ion batteries, high performance anode materials can be prepared by in-situ electrochemical synthesis using alloying products during charging and discharging, and solid-phase in-situ synthesis can also be carried out on the basis of raw material monomers.
