A Group of Cyclic Siloxane and Silazane Polymer Films as Nanoscale Electrolytes for Microbattery Architectures
Nanoscale (10–50 nm) thin
films of cyclic siloxane and silazane
polymers were synthesized by initiated chemical vapor deposition (iCVD).
We have previously demonstrated that the non-line-of-sight iCVD synthesis
process can create uniform conformal coverage of these films over
complex nonplanar surfaces. This work will introduce the protocols
used to convert these dielectric polymer films into ionic conductors
at room temperature. The excellent thickness and morphological stability
of these films will be demonstrated along with experiments that determine
the ion content in the films. Finally, computational calculations
will be used to elucidate the chemical nature of the ion doping and
transport processes. These nanoscale, conformal, ionically conducting
polymer thin films are attractive as a novel class of nanoscale electrolytes
for emerging miniaturized or microbattery architectures such as three-dimensional
(3D) batteries which combine high energy (due to high surface area)
and power density (due to short ionic transport lengths) within small
areal footprints
