Description

technical field [0001] The invention relates to a fabric-shaped polymer battery and a preparation method thereof, belonging to the technical field of batteries. technical background [0002] Wearable electronic smart textiles are considered to be an important development direction for the high-end and intelligent textile industry in the future. Soft, lightweight energy storage devices are key components of smart textiles. The non-flexible structure of traditional energy storage devices such as batteries is difficult to meet the application requirements of smart textiles. Therefore, the development of fabric-based flexible energy conversion / energy storage devices has become an important task for the development of smart textiles. [0003] In recent years, the study of paper-based flexible batteries has received extensive attention. Finland's ENFUCELL company has developed a low-cost ultra-thin paper battery, which is assembled from a thin layer of paper that is galvanized ...
