Abstract

Our development facilitates the manufacturing of inexpensive supercapacitors by printing technology. The components are designed to be used in high-volume applications such as RFID or packaging. We have applied activated carbon ink electrodes with various electrolytes including aqueous sodium nitrate and TEABF4 in propylene carbonate. The electrode structures have been fabricated using either pilot scale rotary screen printing or laboratory scale bar coater. Coated aluminium laminates have been used as substrates and encapsulation. The geometric area of the printed supercapacitors has been 2-100 cm2 resulting to 0.2 - 20 F capacitance. The cycle life exceeds 50000 cycles.
