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

Abstract

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.
