| Abstract |
|
1.5 V and 3.0 V-class film-type primary batteries were designed for radio frequency identification (RFID) tag. Efficient fabrication processes such as screen-printings of conducting layer ($25{mu}m$), active material layer ($40{mu}m$ for anode and $80{mu}m$ for cathode), and electrolyte/separator/electrolyte layer ($100{mu}m$), were adopted to give better performances of the 1.5 V-class film-type Leclanch$acute{e}$ primary battery for battery-assisted passive (BAP) RFID tag. Lithium (Li) metal is used as an anode material in a 3.0 V-class film-type $MnO_2||$Li primary battery to increase the operating voltage and discharge capacity for application to active sensor tags of a radio frequency identification system. The fabricated 3.0 V-class film-type Li primary battery passes several safety tests and achieves a discharge capacity of more than 9 mAh $cm^{-2}$. |
