Why UHPC over traditional cyclers?
Existing Test Equipment Excels At
- Test cells to end of life
- Rate capability
- DCIR, GITT
- Application/ drive cycle simulation
Common Theme
Bulk metrics which small uncertainty in raw data or metrics do not matter.
Gaps in Existing Test Equipment
- Understanding impacts on lifetime early (weeks instead of years)
- Material and technology development
- High-throughput studies
- Identifying tiny issues in cells before they become big issues
- Early QC/QA issue detection
Common Theme
Bulk metrics which even small uncertainty can matter a LOT.
NOVONIX® UHPC can do almost anything a normal cycler can do. However, it is designed to measure voltage and current as accurately as possible to detect and elucidate small differences that matter.

The Role of Precision and Accuracy in Cycle Metrics and Data Interpretation
Part 1 of 3 – Introduction to UHPC Terminology and Cell Degradation
In all aspects of battery development – from raw material synthesis and electrolyte formulation to production optimization and warranty estimations, coulomb counting is used to understand the quality, consistency, and performance of batteries and battery cells. From here forward, the term “cell” will be used to refer to a single electrochemical battery cell, and for simplicity, only single-cell testing will be discussed.
The term “coulometry” does not imply one specific test type, but a myriad of applications including: charge discharge cycling, rate testing, impedance testing, etc. In all cases, these types of tests rely on sourcing and sensing the current and voltage applied to a cell with specially designed electronic equipment. The equipment’s ability to accurately and precisely source and sense the applied currents and voltages limits its ability to detect minor differences in performance, leading to varying testing times being needed to obtain enough confidence to make critical, informed decisions.
The data collected from cell testing are then processed and analyzed into time-series and cycle metric data to understand underlying cell performance and degradation. This document will primarily focus on cycle metrics, and discuss in detail the importance of coulomb counting and why NOVONIX Ultra-High Precision Coulometry (UHPC) equipment is needed to obtain critical insights from these data that no other cell testing systems can achieve.
