In this work, the behavior of the anode overhang effect in lithium-ion cells is experimentally investigated and simulated for experimental three electrode cells. An empirical method is presented to transfer the simple 0D-model from the experimental cell level to pouch cells. An anode overhang model will help to correctly interpret cyclic and calendaric aging experiments e.g. in terms of a more reliable and detailed separation of reversible and irreversible capacity losses as well as evaluating the actual state of health of a lithium-ion battery. For the three electrode cells different cathode diameters are used to modulate different sized anode overhang areas. Moreover, the influence of different state of charges on the reversible capacity effect is investigated. To examine the influence of the separator on the evolution of usable cell capacity different separator thicknesses are applied. It is found that the properties of the separator significantly influence the rate at which balancing processes between overhang and active region take place. The results show good accordance of the experimental results to the simulation.

在这项工作中，对锂离子电池中阳极悬垂效应的行为进行了实验研究，并针对实验性的三电极电池进行了模拟。提出了一种将简单的0D模型从实验细胞水平转移到袋状细胞的经验方法。阳极悬垂模型将有助于正确地解释循环和日历老化实验，例如在更可靠，更详细地分离可逆和不可逆容量损失方面，以及评估锂离子电池的实际健康状况。对于三个电极单元，使用不同的阴极直径来调制不同大小的阳极悬垂区域。此外，研究了不同电荷状态对可逆容量效应的影响。为了检查隔板对可用电池容量的演变的影响，应用了不同的隔板厚度。发现隔板的性质显着影响悬伸和活性区之间的平衡过程发生的速率。结果表明，实验结果与仿真结果吻合良好。
