Carbon nanotubes-based electrode for Zn ion batteries

Zn ion batteries (ZIBs) have drawn increasing attentions due to the low cost, high theoretical capacity and excellent safety. Carbon nanotubes (CNTs) as a representative carbon material are widely applied in the design of advanced cathodes and anodes. This review provides a summary of latest developments of CNTs-based electrodes, such as Mn-based and V-based CNTs-containing cathodes and CNTs-modified Zn anodes. Both the preparation and design strategy of the electrodes and the structure-performance relationships are discussed in detail. Finally, a summary of the current progress and future prospects are introduced.
