记录了锂充电电池中不同充电/放电状态下纳米 SnO 阳极的傅里叶变换红外 (FTIR) 光谱。通常发生在碳或碱金属表面的溶剂分解反应在SnO阳极上也发生。表面膜由Li2CO3和ROCO2Li组成。此外，FTIR数据表明ROCO2Li的吸收带变化低于0.7 V，这被认为与第一次放电过程中SnO阳极表面层相对于Li/Li+在0.7 V左右的变化有关。 (C) 2002 年，Elsevier Science B.V. 出版
Fourier-transform infrared (FTIR) spectra of nanometer SnO anodes at different charge/discharge states in lithium rechargeable batteries were recorded. Solvent decomposition reaction that generally presents on the surface of carbon or alkali metal is also presented on SnO anode. The surface film is composed of Li2CO3 and ROCO2Li. In addition, FTIR data indicates that absorption bands of ROCO2Li are changed below 0.7 V, which is believed to be related to the change of the surface layer of SnO anode around 0.7 V versus Li/Li+ during the first discharge process.
