Fast Impedance Tortuosity 

Fast Impedance Tortuosity (FIPT) testing is a measurement technique that allows for a fast determination of the ionic resistance of battery electrodes. This technique has been optimized by Battrion in regard to execution speed and reliability to help shorten Battrion's internal development cycle. We believe that others working on improving battery performance can benefit from our FIPT kit which is why we made it available open-source and for purchase.

 

A fast way to measure ionic resistance!

The ionic resistance (or the MacMullin number) is a key performance metric for any battery electrode. It describes how easily ions can move through the electrode during fast charging or heavy use. This is why it can be useful for  manufacturers that are working on improving their to know the ionic resistance of their battery electrodes.

Battrion's Aligned Graphite Technology is a powerful way to reduce the ionic resistance by up to 50% through aligning graphite particles in an electrode. 

Our FIPT kit 

In the following you find more details about why it is important to measure the ionic resistance of your battery electrode and how it can easily be achieved using Battrion's FIPT kit. In addition, you will find info on how to analyze and interpret the resulting FIPT data and how to identify and eliminate possible error modes.
