Textile-enable Flexible and Foldable Lithium-ion Batteries


Keywords: , , ,

Wearable electronic technology is emerging as the next huge market opportunity after smartphones. Its market revenue is growing at a rate of ~ 25% to reach ~ USD 80 billion by 2025. Flexible lithium-ion (Li-ion) batteries with high electrochemical performance and high mechanical durability, which can be integrated into wearable forms, are highly desired to power up the various wearable electronics. However, current technology fails to achieve simultaneous high flexibility and high energy density. Recently, our laboratory developed patented technology to fabricate highly conductive textiles, and lithium-ion batteries based on these conductive textiles. The metallic textiles are fabricated through a Polymer-assisted Metal Deposition (PAMD) process, in which metal thin films are deposited on functional polymer modified textiles such as cotton and carbon fibers. These metallic textiles show very low resistance (< 0.2 mm) for more than 1000 times without affecting the capacity of the device. This presentation will discuss the principle and development of these metallic textiles and textile-based lithium-ion batteries in detail.
