Major Contributions
 

1. A Janus composite electrolyte is constructed by integrating catalytic yolk-shell MnO@C nanorods with a polyimide (PI) framework, creating an asymmetric structure that simultaneously suppresses polysulfide shuttle via catalytic conversion and provides mechanical robustness.

2. The MnO@C yolk-shell nanorods accelerate polysulfide redox kinetics through strong adsorption and catalytic activity, while the PI matrix offers thermal stability and electrolyte wettability for durable Li–S battery operation.

3. Li–S batteries incorporating the Janus composite electrolyte demonstrate significantly improved cycling stability and capacity retention, validating the multifunctional design strategy for addressing combined challenges of shuttle effect, kinetics, and mechanical integrity.
