Electrochemical Impedance Imaging via the Distribution of Diffusion Times [PDF]

open access: yes, 2017
We develop a mathematical framework to analyze electrochemical impedance spectra in terms of a distribution of diffusion times (DDT) for a parallel array of random finite-length Warburg (diffusion) or Gerischer (reaction-diffusion) circuit elements.

A One-Dimensional Stack Model for Redox Flow Battery Analysis and Operation

open access: yesBatteries, 2019
Current redox flow battery (RFB) stack models are not particularly conducive to accurate yet high-throughput studies of stack operation and design. To facilitate system-level analysis, we have developed a one-dimensional RFB stack model through the ...
