[求助] 关于EIS阻抗谱~求科普:PEIS和GEIS的区别 已有2人参与

如题,在很多电化学工作站中存在着这两种测试,在文献上也看到过这样的解释,但是还是不太理解,还求科普
For example, in corrosion applications, the polarization resistance is often determined under
potential control around the open circuit voltage (OCV). This is an appropriate approach if
the corrosion potential does not change during
the measurement. However, if the corrosion
potential drifts, a potentio controlled experiment defined to run at OCV could result in a
measurement being performed at an anodic or
cathodic potential with respect to the true OCV.
Under galvano control, drift is not a problem
as the desired zero-current condition is maintained throughout the recording, ensuring the
measurement is performed at the true corrosion potential [1]. In battery applications, it is
often of interest to determine the variation of
internal resistance during discharge/charge. In
this case it may also be appropriate to use the
galvano control in EIS measurements

不要为了那些你控制不了的事情而难过

PEIS:施加的激励信号是电势,测量电流,P代表potential
GEIS:施加的激励信号是电流,测量电势,G代表galvano
要做就做最好

没有什么区别 对于较大电阻的体系 建议用GEIRS  那样得到的信号会强一些
