Ion conductive inks and solutions for additive manufacturing of lithium microbatteries
A separator made of ion conductive ink is produced by additive manufacturing. A micro-battery is produced with the separator made of ion conductive ink located between the battery's anode and cathode. The separator functions to keep the anode and cathode apart and to facilitate the transport of ions to produce an operative micro-battery.
