Hydrothermal synthesis of nanostructured $ MnO_{2} $ under magnetic field for rechargeable lithium batteries
Abstract Nanocrystalline $ MnO_{2} $ was synthesized by the hydrothermal method with or without pulsed magnetic fields. It was found that the morphology of the $ MnO_{2} $ prepared without magnetic field has an urchin-like structure, while the $ MnO_{2} $ prepared with magnetic fields has a rambutan-like structure. A pronounced increase in the Brunauer–Emmett–Teller specific surface area was obtained when the intensities of the pulsed magnetic fields increased. The battery performances were improved for the samples prepared with magnetic fields. The $ MnO_{2} $ prepared under a magnetic field of 4 T shows a capacity of 121.8 mAh $ g^{−1} $, while the $ MnO_{2} $ prepared without magnetic field only shows 103.0 mAh $ g^{−1} $ after 30 cycles..
