▎ 摘  要

NOVELTY - Synthesizing carbon monofluoride (CFx)/manganese oxide (Mn5O8) composite anode material comprises using CFxand manganese source as raw materials, obtaining precursor material with rod-shaped manganese oxyhydroxide on the surface of CFxby hydrothermal synthesis, and calcining in oxygen atmosphere to obtain CFx/Mn5O8composite material. USE - The material is useful for lithium-carbon fluoride primary battery (claimed). ADVANTAGE - This material: has excellent high-current discharge performance when used as the anode of lithium carbon fluoride primary battery, and specific capacity of reaching 505 mAh g-1when the current density is 3000 mAg-1; utilizes rod-shaped manganese oxide to form a network structure on surface of CFx; improves the electron conduction and ion transport process; and provides more electrochemically active sites. The method: is simple, efficient and low in cost; and has excellent application prospects in field of lithium-ion primary batteries.
