Abstract
Yarn- or fiber-structured batteries have been studied steadily due to their huge advantages such as light weight, small size and flexibility. Although some fiber structured batteries were reported, large size and complicated fabrication process still remain to be major challenges in developing practical battery systems. In order to address these problems, we fabricated a micro-sized and continuous Ag-Zn fiber battery using wet spinning and electrodeposition. This simple and easy process enables to obtain MWNT fiber electrodes with a length of more than 30 cm and a diameter of about 80 mu m. Silver and zinc were deposited and formed nano-porous structures on the as-prepared wet spun fiber electrodes. Consequently, the Ag-Zn aqueous fiber battery showed an areal capacity of 0.063 mAh/cm(2). Our fiber structured battery could be applicable as energy source of portable, wearable, and micro-sized electronics.
