电化学嵌锂尖晶石型Li_xFe_(3-ω)O_4的电子结构

Electronic Structure of Spinel Type Li_xFe_(3-ω)-O_4 Inserted Lithium Electrochemistry

Mossbauer谱学研究了Li|LiClO_4-PC|Fe_(3-ω)O_4电池放电过程中阳极反应电子在阴极Fe_(3-ω)O_4中的分布得出,一小部分电子进入氧化铁八面体FeO_6的t_(2g)非键轨道成为跳变电子,大部分电子则进入较高能量的反键轨道.

A distribution of electrons came from anode reaction at cathode Fe_(3-ω)O_4 during the discharge of cell Li/LiClO_4-PC/Fe_(3-ω)O_4 were studied by Mossbauer Spectroscopy. It shows that only a small part of electrons enter into t_(2g) non-bonded orbit of octahedral FeO_6 of Fe_(3-ω)O_4, a large amount of electrons get into anti-bonded orbit holded higher energy.
