      Abstract
      Electrochemical Impedance Spectroscopy(EIS) is a standard technique for analyzing batteries in detail. It is immensely powerful as it can yield separate information about various components and interfaces inside while the battery is intact and operational. One drawback of the EIS measurement is the relatively large time it requires.One potential way to improve this issue is the use of the multisine, a technique akin to Fourier Transform techniques in various spectroscopies. In this manuscript, it will be shown that through judicious preparation of excitation signal, proper parameter choice and tweaking, the measurement can be sped up. Under the best conditions, the measurement can be completed within the shortest possible time that transforms to the lowest desired frequency.
