Hierarchical LiFePO(4) with a controllable growth of the (010) facet for lithium-ion batteries

Hierarchically structured LiFePO(4) was successfully synthesized by ionic liquid solvothermal method. These hierarchically structured LiFePO(4) samples were constructed from nanostructured platelets with their (010) facets mainly exposed. To the best of our knowledge, facet control of a hierarchical...

description Hierarchically structured LiFePO(4) was successfully synthesized by ionic liquid solvothermal method. These hierarchically structured LiFePO(4) samples were constructed from nanostructured platelets with their (010) facets mainly exposed. To the best of our knowledge, facet control of a hierarchical LiFePO(4) crystal has not been reported yet. Based on a series of experimental results, a tentative mechanism for the formation of these hierarchical structures was proposed. After these hierarchically structured LiFePO(4) samples were coated with a thin carbon layer and used as cathode materials for lithium-ion batteries, they exhibited excellent high-rate discharge capability and cycling stability. For instance, a capacity of 95% can be maintained for the LiFePO(4) sample at a rate as high as 20 C, even after 1000 cycles.
