Understanding and Designing Lithiophilic Alloyed Metal Anodes for Practical Metal Batteries

Lithiophilic alloyed metal anodes (LAMAs) are emerging as a transformative platform for enabling practical Li metal batteries. By harnessing alloy chemistry, LAMAs combine favorable Li nucleation and growth behavior, robust interfacial chemistry, and mechanical integrity, thereby mitigating the long-standing challenges of manufacturability and cycling stability that have hindered large-scale deployment of Li metal anodes. Nevertheless, a unifying framework that quantitatively defines lithiophilicity, the central design parameter of LAMAs, remains underdeveloped. This review establishes a descriptor-based paradigm to systematically elucidate lithiophilicity, bridging empirical observations with thermodynamic,…
