At NOVONIX, we are lucky to work with the best, and most motivated battery experts in the world. Learning from others is the oldest trick in the book and sometimes it’s too quickly overlooked. Our hope is this blog provides wind at your back.

Let’s accelerate the battery supply chain evolution!

UHPC 101 Part 5 – Coulombic Efficiency: the Breakdown

Introduction The UHPC 101 series has thus far been all about Coulombic Efficiency (CE); how it relates to cell cycle life, how the CE of cells can be normalized to account for different cycle times due to either different cycling rates or different states of charge (CIE/hr) and the two degradation metrics that make up…

UHPC 101 Part 4 – Charge End-point Capacity Slippage

Introduction Thus far, the UHPC 101 series has focused on Coulombic Efficiency (CE); what CE measurements mean and how they can be used to quantify cell performance, how to fairly compare cells cycled at different rates or within different voltage intervals by normalizing for cycle time – giving the Coulombic Inefficiency per hour (CIE/hr), and…

UHPC 101 Part 3 – Capacity Fade

Introduction The first two posts of the UHPC 101 series introduced Coulombic Efficiency (CE); the key metric used to compare and rank cells, and Coulombic Inefficiency per hour (CIE/hr); an extension of CE that allows comparison of cells cycled at both different rates and within different voltage intervals.  For NOVONIX, CE and CIE/hr are invaluable…

UHPC 101 Part 2 – Coulombic Inefficiency Per Hour (CIE/hr)

Introduction In Part 1 of UHPC 101 we discussed Coulombic Efficiency (CE) and introduced it as a critical metric for quantifying cell performance. In general, the closer the CE is to 1, the longer that cell will last. Despite the importance and usefulness of CE, some important considerations are needed to enable fair comparisons of…

UHPC 101 Part 1 – Coulombic Efficiency

Introduction The first battery was developed in 1800, and the first fleet of electric taxis wasn’t made up of Teslas, nor were they yellow, because in 1900 Tesla didn’t exist and taxis weren’t yellow. Since 1800 immense efforts and resources have been dedicated to understanding and developing better batteries. Much has been learned, but above…
