Abstract
This paper reports the manufacturing and testing via pulsed discharging of printed secondary Zn-MnO2 batteries with ionic liquid gel polymer electrolyte (GPE) for IoT and wearable devices. Printed cells under constant current discharge conditions demonstrated average DC internal resistances of 175-225 Ω/cm2. Printed cells under pulsed discharge current demonstrated decreasing internal resistances with increasing cycle number, reaching an average plateau of 125 Ω/cm2 after 50 cycles and remaining beyond 650 cycles. This work improves upon manufacturing methods reported at PowerMEMS 2015 and investigates system-level compatibility with IoT and wearable devices.
