Pulsed-Laser-Deposited Sn[sub 4]P[sub 3] Electrodes for Lithium-Ion Batteries

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 cells cycled between 0 and was found to be about . 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 film electrode. Large reversible capacity of made it a potential anode material for future lithium-ion batteries.
