An interwoven network of MnO₂ nanowires and carbon nanotubes as the anode for bendable lithium-ion batteries.

A porous interwoven network is synthesized, consisting of ultralong MnO2 nanowires and multi-walled carbon nanotubes (MWCNTs). Serving as the anode for a lithium-ion battery, this nanocomposite demonstrates excellent performance due to the synergistic integration of these two 1D materials. Taking advantage of the excellent flexibility and strength of this MnO2-MWCNT network, a full, bendable battery is made that offers high capacity, cycling stability, and low cost.
