Self-assembled core-shell structured S-doped LiMn0.5Fe0.5PO4@N/S-doped C composites were prepared by solvothermal process, which exhibited high discharge capacity.
A self-assembled core-shell structured S-doped LiMn0.5Fe0.5PO4@N/S-doped C composites were prepared by a convenient one-step solvothermal process. The glucose-derived carbon microspheres are coated with LiMn0.5Fe0.5PO4 particles and form secondary particles of core-shell structure. Thioacetamide (TAA) and cetyl-trimethylammonium bromide (CTAB) regulate the growth of LiMn0.5Fe0.5PO4 particles and provide N and S atoms for doping the composites. Electrochemical tests show that appropriate additions of TAA and CTAB can improve the discharge capacity of LiMn0.5Fe0.5PO4 cathodes. The LMFP@G-0.5TC delivers high specific discharge capacities of 166.83 mAh.g(-1) (0.1 C) and 96.47 mAh.g(-1) (10 C).
