Facile synthesis and electrochemical performance of the nanoscaled FePy anode

The electrochemical performance of nanoscaled FePy, synthesized through a facile mechanochemical method with a high phosphorous content, has been evaluated by different techniques. This alloy has higher capacity and better cyclability at various rates than the reported results to date. Particle size and electrode loading density are important for the charge/discharge behavior; solid electrolyte interphase film is beneficial for the cycling performance.179
