In an attempt to upgrade the performance of lithium (Li)-ion batteries, carbon nanotubes (CNTs) have been suggested as a high-energy anode material. However, CNTs induce high irreversible capacity loss during the first cycle of the battery, which still poses a scientific challenge. This study explores CNT tissue as a flexible light-weight alternative to the copper (Cu) foil as an anode current collector in Li-ion batteries, employing graphite active material. The study demonstrates the impact of the graphite mass loaded on the anode performance and suggests that with the increase in the graphite mass, the irreversible capacity loss is considerably decreased. At sufficiently high graphite loadings, the performance during the first cycle becomes comparable to that of an anode utilizing the Cu current collector. This research also presents several distinct chemical pretreatments to the tissue, aiming to fur- ther decrease the irreversible capacity loss. It is suggested that this goal may be accomplished by washing the CNT with sulfuric acid prior to anode preparation, prompting better performance. (C) 2018 Author(s).
