文摘

•: Mesocrystal MnO cubes with percolated nanopores (~10.5 nm) and a porosity of 45% were synthesized.
•: Cationic vacancies enhanced Li ion diffusion coefficient of MnO from 6.96×10⁻¹⁴ cm²/s to 3.33×10⁻¹³ cm²/s.
•: Porous carbon coating improved the electrical conductivity of active materials.
•: The maximum energy density of 227 Wh W h kg⁻¹ was delivered in a full capacitor.
