More than just an empty shell : Multishelled Co 3 O 4 microspheres were synthesized as anode materials for lithium‐ion batteries in high yield and purity. As their porous hollow multishell structure guarantees a shorter Li + diffusion length and sufficient void space to buffer the volume expansion, their rate capacity, cycling performance, and specific capacity were excellent (1615.8 mA h g −1 in the 30th cycle for triple‐shelled Co 3 O 4 ; see graph).
