摘要	A magnetic field induced hydrothermal method is applied to synthesize precursors, followed by annealing to prepare mesoporous MnO microchains. Different morphologies of the ultimate products can be domi-nated by changing the magnetic field strength to acquire good electrochemical performances. The initial high reversible capacity of MnO microchains is 948 mA h g-1. After 250 cycles, the reversible capacity retains about 769 mA h g-1 at 2 C, even after 2000 cycles, the reversible capacity maintains around 198 mA h g-1 at 8 C. The superb electrochemical properties could originate from the mesoporosity of aggregated nanoparticles of the MnO 1D-microchain structure induced by applied magnetic field of 8 T, which is beneficial for the fast transport of Li+ and electron, and can adapt to the dramatic volume change during the Li+ deintercalation.(c) 2022 Elsevier B.V.
