摘要:P4Se3 microparticles are successfully synthesized by simple heating of selenium and amorphous red phosphorus at low temperature. These orthorhombic-phase microparticles exhibit a high reversible capacity of 654 mA h g(-1) at 200 mA g(-1) after 70 cycles and an excellent rate capability with a reversible capacity of 486 mA h g(-1) at 3 A g(-1) as an anode material in sodium-ion batteries. This superior electrochemical performance is attributed to the formation of Na2Se and Se during cycling with better conductivities ( approximate to 10(-6) and approximate to 10(-5) S cm(-1)) and the dominant position of capacitance behavior, which all accelerate kinetic behavior.
