abstract = {Three dimensionally (3D) structured indium tin oxide (ITO)
thin films are synthesized and characterized as a 3D
electrode material for current collection applications.
Using metal citrate chemistry in combination with ultrasonic
spray deposition, a low cost wet-chemical method has been
developed to achieve conformal ITO coatings on non-planar
scaffolds. Although there is room for improvement with
respect to the resistivity (9.9·10−3 Ω∙cm, 220 nm
thick planar films), high quality 3D structured coatings
were shown to exhibit conductive properties based on
ferrocene reactivity. In view of applications in Li-ion
batteries, the electrochemical stability of the current
collector was investigated, indicating that stability is
guaranteed for voltages of 1.5 V and up (vs. Li+/Li). In
addition, subsequent 3D coating of the ITO with WO3 as a
negative electrode (battery) material confirmed the 3D ITO
layer functions as a proper current collector. Using this
approach, an over 4-fold capacity increase was booked for 3D
structured WO3 in comparison to planar samples, confirming
the current collecting capabilities of the 3D ITO coating.
Therefore, the 3D ITO presented is considered as a highly
interesting material for 3D battery applications and
beyond.},
