Can a negative electrode material be used for Li-ion batteries?
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.
What are negative electrode materials?
Various negative electrode materials were reported to date, such as LiV 3 O 8, TiP 2 O 7, LiTi 2 (PO 4) 3, polyaniline, polyimide, MoO 3 coated with polypyrrole, and poly (naphthalene four formyl ethylenediamine). Nevertheless, they demonstrated specific energy density lower than 100 Wh ⋅ kg −1 and very poor cycling stabilities ( 7, 9 – 15 ).
How was the electrochemical test performed in a lithium ion battery?
The electrochemical test was performed in the split cell that was kept inside the glove box that is filled with argon and has low oxygen and moisture levels (less than 0.1 ppm). Si/CNT nano-network coated on a copper substrate served as the negative electrode in the Li-ion battery.
