                      tosylate ([BMIm][Tos]) or in propylene carbonate (PC) gives
                      transition-metal nanoparticles (M-NPs) in non-fluorous media
                      (e.g. [BMIm][Tos] and PC) or metal fluoride nanoparticles
                      (MF2-NPs) for M=Mn, Fe, and Co in [BMIm][BF4]. FeF2-NPs can
                      be prepared upon Fe(AMD)2 decomposition in [BMIm][BF4],
                      [BMIm][PF6], and [BMIm][TfO]. The nanoparticles are stable
                      in the absence of capping ligands (surfactants) for more
                      than 6 weeks. The crystalline phases of the metal or metal
                      fluoride synthesized in [BMIm][BF4] were identified by
                      powder X-ray diffraction (PXRD) to exclusively Ni- and
                      Cu-NPs or to solely MF2-NPs for M=Mn, Fe, and Co. The size
                      and size dispersion of the nanoparticles were determined by
                      transmission electron microscopy (TEM) to an average
                      diameter of 2(±2) to 14(±4) nm for the M-NPs, except for
                      the Cu-NPs in PC, which were 51(±8) nm. The MF2-NPs from
                      [BMIm][BF4] were 15(±4) to 65(±18) nm. The average
                      diameter from TEM is in fair agreement with the size
                      evaluated from PXRD with the Scherrer equation. The
                      characterization was complemented by energy-dispersive X-ray
                      spectroscopy (EDX). Electrochemical investigations of the
                      CoF2-NPs as cathode materials for lithium-ion batteries were
                      simply evaluated by galvanostatic charge/discharge profiles,
                      and the results indicated that the reversible capacity of
                      the CoF2-NPs was much lower than the theoretical value,
                      which may have originated from the complex conversion
                      reaction mechanism and residue on the surface of the
                      nanoparticles.},
