Reversible formation of networked porous Sb nanoparticles during cycling: Sb nanoparticles encapsulated in a nitrogen-doped carbon matrix with nanorod structures for high-performance Li-ion batteries

Due to networked porous formation of Sb nanoparticles after delithiation, the Sb@N-CM nanorods anode exhibits a high reversible capacity, high coulombic efficiency, and excellent rate capability.
