Liquid-feed flame spray pyrolysis as alternative synthesis for electrochemically active nano-sized Li2MnSiO4

摘要: A novel liquid-feed flame spray pyrolysis synthesis with reducing post-heat treatment yielding highly phase pure nano-sized and carbon-coated Li2MnSiO4 is reported. In contrast to most reported routes, aerosol combustion methods are scalable not as time consuming wet chemical syntheses. Flame was performed using solutions varying ratios of H2O, EtOH p-Xylene. The importance solution combustibility form loosely agglomerated nanoparticles highlighted. Particles from the p-Xylene-aided showed a mean particle size 20 nm Pmn2 1 structure after annealing carbon coating. electrochemical performance cathode material assessed by galvanostatic cycling in situ XRD half cells. highest discharge capacity observed 190 mAh g−1 at room temperature rate C/50.
