High Voltage Electrophoretic Deposition of Aligned Nanoforests for Scalable Nanomanufacturing of Electrochemical Energy Storage Devices
Abstract: High voltage electrophoretic deposition (HVEPD) has been used to obtain forests of
aligned multi-walled carbon nanotubes (MWCNTs) on long strips of flexible, conductive substrates.
Successful design and integration of a continuous HVEPD setup has enabled scalable fabrication of
electrodes for electrochemical energy storage. The mechanism of continuous HVEPD has been
investigated to ensure appropriate alignment. Well-aligned forests of MWCNTs were obtained
using a conductive holding layer which helped reduce internal resistance and enhance the
electrochemical performance of the electrodes.
