由于缺少NCM811的热力学数据，采用Li，Ni，Mn和Co的金属氧化

由于缺少NCM811的热力学数据，采用Li，Ni，Mn和Co的金属氧化物的氯化反应来代替计算焙烧过程的热力学。可能发生的氯化反应分为两部分：低温时金属氧化物直接与NH4Cl的反应，高温时金属氧化物与NH4Cl分解产出的HCl气体的反应。反应如式(2)-(13)所示。

Due to the lack of thermodynamic data of ncm811, the chlorination of metal oxides of Li, Ni, Mn and CO is used instead of calculating the thermodynamics of roasting process. The possible chlorination reaction is divided into two parts: the direct reaction of metal oxide with NH4Cl at low temperature and the reaction of metal oxide with HCl gas produced by NH4Cl decomposition at high temperature. The reaction is shown in formulas (2) - (13).
