A method is reported for the first time for the selected‐control, large‐scale synthesis of monodispersed Fe 3 O 4 @C core–shell spheres, chains, and rings with tunable magnetic properties based on structural evolution from eccentric Fe 2 O 3 @poly(acrylic acid) core–shell nanoparticles. The Fe 3 O 4 @C core–shell spheres, chains, and rings were investigated as anode materials for lithium‐ion batteries. Furthermore, a possible formation mechanism of Fe 3 O 4 @C core–shell chains and rings has also been proposed.
