A layer‐by‐layer nano‐architecture is successfully fabricated for use as a cathode, via electrostatic interaction and vacuum filtration of positively charged V 2 O 5 nanospheres and negative‐charge‐terminated multiwalled carbon nanotube (MWCNT). As shown by K. Huang, J. X. Zhong, and co‐workers on page 5633, the V 2 O 5 nanospheres are closely intercalated between the MWCNT layers, minimizing the disadvantageous voids, and enhancing the overall conductivity of the composite electrode.
