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 μm. 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/cm². Our fiber structured battery could be applicable as energy source of portable, wearable, and micro‐sized electronics.

制造具有微型直径的连续纤维银锌电池

纱线或纤维结构电池由于具有重量轻，体积小和柔韧性大等优点，因此一直在进行稳定的研究。尽管已经报道了一些纤维结构的电池，但是大尺寸和复杂的制造过程仍然是开发实际电池系统的主要挑战。为了解决这些问题，我们使用湿法纺丝和电沉积工艺制造了微型连续的Ag-Zn纤维电池。该简单且容易的方法使得能够获得长度大于30cm且直径为约80μm的MWNT纤维电极。在准备好的湿纺纤维电极上沉积了银和锌，并形成了纳米孔结构。因此，Ag-Zn水性纤维电池的单位面积容量为0.063mAh / cm ^2。。我们的纤维结构电池可以用作便携式，可穿戴和微型电子设备的能源。
