In situ synthesis of ultrasmall MnO nanoparticles encapsulated by a nitrogen-doped carbon matrix for high-performance lithium-ion batteries

Herein, ultrasmall MnO nanoparticles encapsulated by nitrogen-rich doped carbon matrix hybrids are synthesized by annealing ethylenediaminetetraacetic manganese [Mn-2(EDTA)] precursors for the first time. The resulting MnO@NDC composite exhibits excellent rate capability and outstanding cycling stability as an advanced anode material for lithium-ion batteries.
