چکیده انگلیسی
Practical, high-yield mesoporous organic polymer (MOP) spheres were successfully synthesized by a novel self-template method, which can be used as fillers to prepare poly (ethylene oxide) (PEO)-based polymer electrolytes membranes. The result shows that both the electrical conductivity and lithium-ion conductivity of PEO-based electrolytes can be improved effectively by adding the MOP filler. The electrolyte membranes are mechanically robust, thermally stable to over 270â¯Â°C, and can effectively block dendrites penetrating from metallic-lithium anode to cathode. The Li+ transfer conductivity of composite electrolyte membrane increases to 4.4â¯Ãâ¯10â4â¯Sâ¯cmâ1 at 63â¯Â°C. All-solid-state LiFePO4/MOP-PEO-LiTFSI/Li cell shows excellent cycling (144â¯mAhâ¯gâ1 after 300â¯cycles) and rate (167â¯mAhâ¯gâ1 at 0.2â¯C, 170â¯mAhâ¯gâ1 at 0.5â¯C, 160â¯mAhâ¯gâ1 at 1â¯C and 145â¯mAhâ¯gâ1 at 2â¯C) performance.
