摘要：

Sn4P3 thin films have been successfully fabricated by reactive pulsed laser deposition for the first time and were investigated for their electrochemistry with lithium. The reversible discharge capacity of Sn4P3/Li cells cycled between 0 and 3.0 V was found to be about 906.2 mAh g(-1). By using ex situ X-ray diffraction, transmission electron microscopy, and selected-area electron diffraction measurements, both the classical alloying process and the phosphorization/reduction of nanosized Sn were revealed in the lithium electrochemical reaction of Sn4P3 film electrode. Large reversible capacity of Sn4P3 made it a potential anode material for future lithium-ion batteries.
