Abstract
LiMnPO4 nanosheets for use in lithium-ion battery cathode materials were synthesized using a solvothermal method under a water and ethylene glycol mixed solvent system. Well-dispersed rectangular sheet particles oriented by two different facets, {100} or {010}, were obtained by changing the source mixing sequence, and the lateral size of each nanosheet could be controlled by adding appropriate amounts of surfactants. Both LiMnPO4/C nanosheets with different oriented facets had large discharge capacities and excellent cycle stabilities. Additionally, the LiMnPO4/C nanosheets of size (50-100) × 200 nm, with the {010} facet exposed, had an outstanding rate capability at 55 °C, which discharge capacities of 147, 135, 123, and 112 mA h g-1 at 1, 2, 5, and 10C, respectively.
