Self‐Templated Formation of Uniform F‐CuO Hollow Octahedra for Lithium Ion Batteries

Novel F-CuO and FeOOH hollow octahedra are developed through a facile structure-evolution reaction. The formation of interior voids within the hierarchical octahedra is motivated by the Cl− ions based etching, under a precise control over reaction agents and conditions. Owing to the synergistic effect of unique structural features and favorable composition, the hollow octahedra exhibit superior lithium-storage properties.
