Revolutionize Your Battery Innovations

Explore the Possibilities with NEI’s Electrochemical Testing Services

How is NEI Different?

We take a Whole of Cell, Holistic Approach to Testing New Materials

This means we take into account all parts of a cell, so the results are more meaningful, relevant, and applicable to real world applications. For example, if you have a new anode material, we will fabricate cells where the anode powder has been processed to mimic commercial anode electrodes and then subject it to meaningful test protocols.

We have an Extensive Materials Background

Our staff’s extensive materials background allows us to shed light on the interactions within the cell at the atomic/molecular level, which is immensely helpful in optimizing new materials and making them commercially relevant.

We Bridge the Commercialization Gap

Our material-centric approach to electrochemistry bridges the commercialization gap faster, better, and at lower cost than our competition.
