标题： Effect of thickness on the maximum potential drop of current collectors

摘要： 实现电化学储能单元高功率能力的基本原理是尽可能降低整体电阻。 电流收集系统的电阻在过去没有受到足够的关注，可能是因为它被认为对低功率电池和超级电容器不重要。 然而，高功率电池的必要性使得其他内部电阻源被减少，电流收集器的电位降变得更为重要。 此外，储能设备的微型化可能会增加电流收集器中的欧姆损耗。 在本研究中，我们开发了一个电气模型来评估电流收集器厚度对最大电位降的影响。 我们发现，电流收集器的厚度是一个关键参数，可以显著增加最大电位降。 事实上，当厚度大于500 lm时，电流收集器的最大电位降几乎保持不变，但低于此值时，最大电位降与厚度之间存在反比关系。 我们还分析了材料和汇流排位置对最大电位降的影响。 显示英文摘要

摘要： The basic principle for achieving high-power capability on an electrochemical energy storage cell is minimizing the overall resistance. The resistance due to current collecting systems has not received sufficient attention in the past, presumably because it was not considered of significance for low-power batteries and supercapacitors. However, the necessity of high-power cells has reduced other sources of the inner resistance, and the current collector potential drop has become more important. Moreover, the miniaturization of energy storage devices could increase the ohmic loses in current collectors. In this work, we have developed an electrical model to assess the effect of the current collector thickness on the maximum potential drop. We have found that the thickness of current collectors is a critical parameter that can increase the maximum potential drop drastically. Indeed, the maximum potential drop of current collectors remains almost constant for thicknesses greater than 500 lm, but below this value, there is an inverse relationship between the maximum potential drop and the thickness. We have also analyzed the effect of the material and tab position in the maximum potential drop.
