摘要：

Pursuing eco-efficient sustainable synthesis, we have designed a two-step 'splash combustion synthesis (CS)' method to obtain Fe(II)-based positive-electrodes starting with cheap Fe(III) precursors. As a proof-of-concept test, we can produce phase-pure nanoscale, carbon-coated Li2FeP2O7 in just 1 minute, delivering excellent electrochemical performance. CS forms a novel economical and energy-savvy route to form excellent Fe-based polyanionic positive-electrode compounds.
