Micro-Battery Development for Fish Tracking System Applications

Specifically designed micro-batteries have been developed for injectable fish tags. Through appropriate lamination and fabrication process, cylindrical CFx-based micro-batteries have been prepared in the lab readily for mass production. High pulse current and required service life have both been achieved as well as doubling the gravimetric energy density of the battery. The newly designed micro-batteries have intrinsically low impedance, leading to significantly improved electrochemical performances at low temperatures. Successful field trial by using the micro-battery powered transmitters injected into fish has been demonstrated, providing an exemplary model of transferring fundamental research into practical devices with controlled qualities.
