Here we show that the Onsager cross terms for ion-electron interactions are not an artifact, but the necessity to phenomenologically and completely describe the mass/charge transport of a mixed ionic-electronic conductor in terms of mobile charged components which are the only experimentally operable species. The use of an appropriate comprehensive defect model may help to reduce the cross terms (which depend on the choice of formal charge of the mobile defects), but it cannot obviate them if long-range Coulombic interactions are in action among the defects.
在此我们表明，离子 - 电子相互作用的昂萨格交叉项并非人为产物，而是根据移动带电成分从唯象学角度完整描述混合离子 - 电子导体的质量/电荷传输的必要条件，这些移动带电成分是仅有的可通过实验操作的物种。使用合适的综合缺陷模型可能有助于减少交叉项（其取决于移动缺陷形式电荷的选择），但如果缺陷之间存在长程库仑相互作用，就无法消除这些交叉项。
