Fiber‐Shaped Batteries Towards High Performance and Perspectives of Corresponding Integrated Battery Textiles.

Recently, due to its flexibility and ease of integration into wearable electronics, interest in fiber‐shaped batteries (FSBs) is burgeoning. While there is much research focused on improving the electrochemical performance of FSBs, little work is done to evaluate the safety and comfort of integrated FSBs for wearable electronics, which will significantly hinder the further development of high‐performance FSBs and their commercialization. In this review, the design, integration, and evaluation of FSBs incorporated in common textiles are fully discussed. Traditional textile characterization techniques and modern methods to evaluate its durability are also summarized. Finally, in view of developing commercial wearable battery textiles, a perspective toward improving the design of high‐performance FSB is presented. [ABSTRACT FROM AUTHOR]
