Inkjet Printed Ultra-Thin Conformal Zinc-Silver Battery

Abstract

Flexible printed electronics and photonics technologies are in demand because they are cost-effective and quickly reconfigurable. Zinc-silver battery can help towards development of body conformal wearable electronics. The study evaluate planar sec-ondary Ag2O-Zn battery fabricated using the inkjet printing technology. Polyethylene naphthalate (PEN) is used as polymer substrate and carbon nanotubes material is used as current collectors. The demonstrated battery achieves an capacity of 4 mAh with active electrode area of 14 cm2 and thickness of 0.2 mm.
