摘要
Abstract
Lithium fluoride carbon(Li/CFx)batteries are known for their exceptionally high specific energy among lithium primary batteries.However,they face challenges such as low voltage plateau,low actual specific energy,and poor rate performance during discharge.This article uses commercial Keqin black as a carbon source and uses a solid-phase direct fluorination method to prepare fluorinated Keqin black(FKB).To enhance material properties,the FKB/RGO composite is prepared via a solution thermal reduction method.This approach improves material conductivity,increases the active contact area between the electrode material and the electrolyte,and shortens the lithium-ion diffusion pathway.The resulting FKB/RGO material achieves a discharge specific capacity of 858.4 mAh/g at 0.1 C and a discharge capacity of 550.6 mAh/g at 10 C,demonstrating excellent energy density and rate performance.This work contributes to promoting the engineering application of FKB/RGO materials in high-performance battery systems.关键词
