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 limitations in potential for the electroactive material of the negative electrode are less important than in the past thanks to the advent of 5 V electrode materials for the cathode in lithium-cell batteries. However, to maintain cell voltage, a deep study of new electrolyte–solvent combinations is required.
Lithium (Li) metal is widely recognized as a highly promising negative electrode material for next-generation high-energy-density rechargeable batteries due to its exceptional specific capacity (3860 mAh g −1), low electrochemical potential (−3.04 V vs. standard hydrogen electrode), and low density (0.534 g cm −3).
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.
Two lines of research can be distinguished: (i) improvement of LiCoO 2 and carbon-based materials, and (ii) replacement of the electrode materials by others with different composition and structure. Concerning the positive electrode, the replacement of lithium cobaltate has been shown to be a difficult task.
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).
