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 MnO ₂-MWCNT network, a full, bendable battery is made that offers high capacity, cycling stability, and low cost. Bending the rules: An anode comprising interwoven ultralong MnO₂ nanowires and multi-walled carbon nanotubes (MWCNTs) is made. By taking advantage of the synergy between these materials, and their strength and flexibility, a low-cost, bendable lithium-ion battery is constructed, demonstrating high capacity and cycling stability.
