Abstract
Lithium manganese iron phosphate (LMFP) is increasingly attracting attention in the industry due to its excellent performance advantages. However, its limited electrical conductivity and lithium-ion diffusivity still hinder its practical application. In this paper, we introduced a method for the synthesis of LiMn0.8Fe0.2PO4/C nano spherical composites by using cetyltrimethylammonium bromide (CTAB)-assisted hydrothermal method. The material doped with 1 mmol of CTAB(LMFP/C-1) significantly prevented particle agglomeration and reduced the particle size, which improved the electrical conductivity of the material and exhibited excellent multiplicative and cycling properties. The results showed that LMFP-1can release the initial specific capacity around 152.4 mAh·g−1 at 0.1C, and the capacity retention rate was 94.35 % after 500 cycles at 1C. This research provides a method to improve the cathode materials for lithium-ion batteries.
