Transparent conducting films have a wide range of applications in the fields of flat panel displays, solar cells, and touch panels for their both good conductivity and light transmittance. Carbon nanotubes (CNTs) transparent conducting film has become a potential alternative for next-generation transparent conducting film systems owing to high conductivity, light transmittance and flexibility. The multiwalled carbon nanotubes (MWCNTs) conductive liquid was prepared by dispersing MWCNTs in alcohol through ultrasonic and high-speed shearing process with an addition of carbon nanotube alcohol dispersant (TNADIS) as the dispersant. The transparent conducting film was fabricated on polyethylene terephthalate (PET) transparent film by spin-coating process. The film was used as interlayer between the electrode and the separator to improve electrochemical performance of lithium-sulfur (Li-S) batteries.

Lithium-ion capacitors (LICs) have a wide range of applications in the fields of hybrid electric vehicles (HEVs) and electric vehicles (EVs) for their both high energy density and high power density. Lithium-ion capacitors have become a potential alternative for next-generation chemical energy storage equipment owing to high energy density, high power density, and excellent cycle performance. The prelithiated multiwalled carbon nanotubes (MWCNTs) electrode was prepared by internal short circuit (ISC) and doping to intercalate lithium into MWCNTs. SLMP and lithium metal were used as lithium resources, respectively. The prelithiated carbon nanotubes were used as anode and activated carbon electrode as cathode. The capacitors were assembled in a glove box filled with argon. The prelithiated MWCNTs electrode eliminated irreversible capacity and improved substantially electrochemical performance of lithium-ion capacitors.
