Pomegranate-like multicore–shell Mn₃O₄ encapsulated mesoporous N-doped carbon nanospheres with an internal void space for high-performance lithium-ion batteries

A new class of pomegranate-like multicore-shell Mn3O4 encapsulated mesoporous N-doped carbon nanospheres (m-N-C@Mn3O4) with an internal void space has been developed. The novel nanostructure of m-N-C@Mn3O4 nanopomegranates has been proven to significantly alleviate the volume change and improve the electronic conductivity, which endows lithium-ion batteries with superior rate performance and cycling stability.
