NOVONIX – Performing DCIR Measurements with a NOVONIX UHPC System

Direct current internal resistance (DCIR) measurements provide kinetic information that can complement conventional UHPC metrics used to rank lifetime capabilities like capacity fade and charge endpoint capacity slippage. This document details a simple procedure for obtaining internal resistance values as a function of state-of-charge, utilizing the user defined variables and expressions functionality available in UHPC Protocol v2.6.0 and newer. Analysis of results is briefly discussed.
