Fabrication of NiMn2O4/C hollow spheres with a trilaminar shell structure as an anode material for sodium-ion batteries

NiMn2O4/C hollow spheres with sandwich-structured shells were fabricated by a hydrothermal method. Leveraging the mesoporous design of the carbon hollow spheres, NiMn2O4 nanosheets were evenly dispersed on both the inner and outer surfaces of the carbon shells. NiMn2O4/C demonstrated excellent rate capability and prolonged cycling durability for sodium ion storage.

Automated summary

NiMn2O4/C hollow spheres with sandwich-structured shells were synthesized by hydrothermal method. The mesoporous carbon hollow spheres facilitated the uniform dispersion of NiMn2O4 nanosheets on both inner and outer surfaces of the carbon shells. NiMn2O4/C exhibited excellent rate capability and prolonged cycling durability for sodium ion storage.
