Elaboration of a microstructured inkjet-printed carbon electrochemical capacitor

---

a b s t r a c t
Carbon-based micro-supercapacitors dedicated to energy storage in self-powered modules were fabricated
with inkjet printing technology on silicon substrate.Aninkwasfirst prepared by mixing an activated
carbon powder with a PTFE polymer binder in ethylene glycol stabilized with a surfactant then deposited
by inkjet on patterned gold current collectors with the substrate heated at 140 ◦C in order to assure a
good homogeneity. Electrochemical micro-capacitors with electrodes in an interdigital configuration were fabricated, and characterized using electrochemical techniques in 1M Et4NBF4 propylene carbonate electrolyte. These micro-devices show an excellent capacitive behavior over a wide potential range of 2.5V for a cell capacitance of 2.1mFcm−2. The newly developed technology will allow the integration of the storage device as close as possible to the MEMS-based energy harvesting device, minimizing power losses through connections
