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 µm), active material layer (40 µm for anode and 80 µm for cathode), and electrolyte/separator/electrolyte layer (100 µm), were adopted to give better performances of the 1.5 V-class film-type Leclanché 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 .
