Construction of Multifunctional Conductive Carbon-Based Cathode Additives for Boosting Li6PS5Cl-Based All-Solid-State Lithium Batteries

This work provides a brand-new approach to the “conversion-protection” strategy to overcome the drawbacks of composite cathode interfaces. The Mo 3 Ni 3 N not only makes it difficult for hydroxide groups (-OH) to survive on the surface but also allows the in situ surface reconstruction to generate the ultra-stable MoS 2 -Mo 3 Ni 3 N heterostructures after the initial cycling stage. The Mo-Ni@NPCs/LCO/LPSC-based ASSLBs achieve high-capacity retention (90.62%) and excellent cycle life (1000 cycles).
