Interface-reinforced high-capacity fiber cathode for wearable Li-S batteries.

ABSTRACT: Fiber-shaped Li-S batteries are attractive for constructing smart textiles as flexible power solutions due to their high theoretical specific capacity, flexibility and wearability. However, severe interfacial issues, such as the shuttle effect of polysulfides on the cathode side, lead to capacity decay and poor lifespan of the batteries. Herein, we report a fiber-shaped composite cathode with collaborative interface interactions to maintain electrode integrity and boost electrochemical performance. In this architecture, nanosulfur-polyvinylpyrrolidone (nanoS-PVP) particles are uniformly implanted into the few-layer Ti₃C₂T _x with outstanding electrical conductivity and then coated on aluminum (Al) fiber current collectors. Impressively, nanoS and solu
