Abstract

Lithium ion batteries with high electrochemical performance and high flexibility are regarded as promising energy storage devices for portable and wearable electronics. Here, we report a flexible and foldable lithium-ion battery based on highly conductive three dimensional (3-D) metallic textiles. The 3-D metallic textile current collectors are fabricated through a polymer-assisted metal deposition (PAMD) process. After deposition, these textiles possess a sheet resistance less than 1 ohm/sq., and exhibit great flexibility and good washing ability (30 commercial washes). Benefiting from the large surface area and high conductivity of the textile current collectors, the as-fabricated lithium-ion pouch cells achieve a highest energy density of 45 Wh/L and highest power density of 600 W/L. Moreover, the 3-D architecture of metallic textiles further enhances the mechanical stability of the device, thus the device can be folded for more than 1000 times without obvious change in the electrochemical performance.
