The research aims to address challenges in lithium metal batteries due to electrode-specific degradation pathways.
Proposed a Janus separator with distinct layers for the anode and cathode.
Fabricated a conducting hybrid polypyrrole-silicon oxide layer to manage lithium ion flux at the anode.
Developed a polydopamine-coated boehmite layer to capture transition metals at the cathode.
Achieved over 96% mitigation of transition metal ion migration at the cathode.
Demonstrated improved interfacial stability and long-term cycling performance in lithium metal batteries.
Showed effective suppression of lithium dendrite formation, enhancing overall safety.
