通过对烧结后含锂盐炭阳极糊的红外光谱、Ｘ 射线衍射和热分析研究表明， 在铝电解的温度和条件下， 炭阳极中的Ｌｉ２ＣＯ３ 仅少量分解且仍是其主要存在形式。由于碳的存在使Ｌｉ２ＣＯ３ 的分解率大大降低， 使其分解温度大大高于文献报道的Ｌｉ２ＣＯ３ 的热分解温度。
The infrared spectra, X-ray diffraction and thermal analysis of the anode paste containing lithium salt after sintering showed that only a small amount of Li2CO3 was decomposed in the carbon anode at the temperature and conditions of aluminum electrolysis and it is still the main existing form. Due to the presence of carbon, the decomposition rate of Li2CO3 is greatly reduced, and the decomposition temperature is much higher than the thermal decomposition temperature of Li2CO3 reported in the literature.
