Textile-Based Battery Using a Biodegradable Gel-Electrolyte

Lightweight and flexible batteries with natural gel-electrolyte between textile-based electrodes are presented, demonstrating a discharge capacity of 100 mAh g-1 at 14 mA g-1 with respect to the anode. Aging processes of the gel-matrix are investigated, showing that the device can be refreshed by re-wetting the gel-electrolyte. Due to the textile-based architecture, the batteries can be bent up to 180° with minor influence on the battery voltage.
