Abstract The electrochemical performance of all-solid-state lithium batteries (ASSLBs) can be prominently enhanced by minimizing the detrimental degradation solid electrolytes through their undesirable side reactions with conductive carbon additives (CCAs) inside composite cathodes. Herein, well-defined Mo 3 Ni N nanosheets embedded onto N-doped porous carbons (NPCs) substrate are successfully synthesized (Mo-Ni@NPCs) as CCAs LiCoO 2 for Li 6 PSC 5 Cl (LPSCl)-based ASSLBs. This nano-composite not only makes it difficult hydroxide groups (–OH) to survive on surface but also allows in situ reconstruction generate ultra-stable MoS -Mo heterostructures after initial cycling stage. These effectively prevent occurrence OH-induced LPSC decomposition reaction from producing harmful insulating sulfates, well simultaneously constructing highly-efficient electrons/ions dual-migration pathways at cathode interfaces facilitate improvement both electrons and + ions conductivities With this approach, fine-tuned Mo-Ni@NPCs deliver extremely outstanding performance, including an ultra-high first discharge-specific capacity 148.61 mAh g −1 (0.1C), a high Coulombic efficiency (94.01%), retention rate 1000 cycles still attain 90.62%. work provides brand-new approach “conversion-protection” strategy overcome drawbacks cathodes instability further promotes commercialization
