Facile solvothermal preparation of nanostructured MnF2 as outstanding anode materials for lithium-ion batteries

Abstract MnF 2 particles with the average size of around 26 nm have been prepared successfully with NH 4 HF 2 as a fluorine source by a simple solvothermal method. Compared with previous reports, as-prepared MnF 2 shows evidently improved cycle performance with a high reversible capability 481.9 mAh g −1 at 0.1 C for the first cycle and stable discharge capability 530.5 mAh g −1 and 359.2 mAh g −1 at 0.1 C and 1 C for 250 cycles respectively, which indicates its promising application as anode for lithium-ion batteries.
