采用原位和频振动光谱法研究了碳酸丙烯酯（PC）在锂离子电池正极材料LiCoO2薄膜表面的吸附行为。PC分子在LiCoO2表面的两种吸附模式具有相反的取向几何结构已被观察到。PC的吸附结构受Li+的溶剂化过程的影响。
The adsorption of propylene carbonate (PC) on the surface of the LiCoO2 thin-film, one of the important cathode materials used in the lithium-ion (Li-ion) battery, has been investigated by in situ sum frequency generation vibrational spectroscopy. Two adsorption modes of PC molecules with opposite orientation geometries on the LiCoO2 surface have been observed. The adsorption structures of PC are affected by the solvation process of the Li+ ion.
