Surface-Stabilized and Lightweight Metallic PET Fabrics for Flexible and Energy-Dense Li-Ion Batteries.

ABSTRACT: Current collectors are indispensable components in flexible lithium batteries. However, commercially used current collectors are heavy and rigid, severely limiting the energy density and flexibility of the batteries. Metallic polyethylene terephthalate fabrics (MPETs) have emerged as promising alternatives due to their lightweight nature, low cost, and excellent flexibility. Despite these advantages, the chemical and electrochemical stability of MPETs under battery operating conditions remains largely unexplored. Herein, the rapid degradation mechanism of MPETs in working batteries and propose effective surface-stabilization strategies to enhance their long-term stability is systematically investigated. An electroplating-repair method is developed to fabricate etching-proof MPETs for anode
