Li-ion battery materials: present and future. Issues and challenges facing rechargeable lithium batteries. The successful operation of metal fluorides at elevated temperatures opens a new avenue for their practical applications and future successful commercialization. Our findings suggest that the formation of an elastic, thin and homogeneous cathode electrolyte interphase layer on active particles is a key for stable performance. The absence of liquid solvents reduced electrolyte decomposition, while mechanical properties of the solid polymer electrolyte enhanced cathode structural stability. We demonstrate long-cycle stability for over 300 cycles at 50 ☌ attained in high-capacity (>450 mAh g −1) FeF 2 cathodes. Here we report that replacing commonly used organic electrolytes with solid polymer electrolytes may overcome this hurdle. Unfortunately, such cathodes suffer from extremely poor performance at elevated temperatures, which may prevent their use in large-scale energy storage applications. Metal fluoride conversion cathodes offer a pathway towards developing lower-cost Li-ion batteries.
