SWCNTs are an ideal conducting agent for both cathode and anode of EV batteries, because a small amount as low as 0.16 wt.% (owing to their high aspect ratio) is sufficient to achieve good electrical conductivity of the electrode.
The inclusion of conductive carbon materials into lithium-ion batteries (LIBs) is essential for constructing an electrical network of electrodes. Considering the demand for cells in electric vehicles (e.g., higher energy density and lower cell cost), the replacement of the currently used carbon black with carbon nanotubes (CNTs) seems inevitable.
Battery electrodes need to be fabricated from the individual constituents. The best hypothetical conductive network is therefore of little use if it cannot be processed into a working electrode. Commercial batteries consist of thin electrode films of about 50 to 100 µm thickness.
Rechargeable metal batteries are an attractive class of next-generation batteries thanks to the high abundance of most of the metals involved, and to their high capacity and energy density compared to insertion-type anodes.
Conductive networks are integral components in Li-ion battery electrodes, serving the dual function of providing electrons to the active material while its porosity ensures Li-ion electrolyte accessibility to deliver and release Li-ions, thereby ultimately determining the electrochemical performance of the battery.
The driving distance of EVs should be over 500 km on a single charge when compared with a combustion engine. To increase the energy density of EV batteries, the replacement of carbon black with CNTs is an inevitable choice, because the smaller the amount of conducting agent, the higher the energy density of LIBs.
