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 (≈10−6 and ≈10−5 S cm−1) and the dominant position of capacitance behavior, which all accelerate kinetic behavior.
