Benefits of UHPC technology

Accurate Measurements

Allows accurate measurements of electrochemical processes within a cell. This enables non-destructive understanding of how battery chemistry is changing from cycle-to-cycle

Measure Coulombic Efficiency, up to five significant figures, to enable reliable comparisons of cells in a fraction of the time that it would take on other cyclers

Unique Observations

Observe cycle metrics unique to ultra-high precision, such as end-point capacity slippage

Precise Evaluation

Evaluate active material loss, lithium inventory loss, electrolyte oxidation and more

UHPC 101

NOVONIX’s Ultra-High Precision Coulometry systems provide industry leading low noise and high-accuracy electronics to make precise measurements that are reliable and repeatable.

Relied on by industry leaders

Leading battery makers, researchers, and equipment manufacturers including Panasonic, CATL, LG Energy Solutions, Samsung SDI, SK Innovation, and numerous consumer electronics and automotive OEMs rely on UHPC’s accuracy, reliability, and precision.


NOVONIX UHPC systems are fully capable battery cyclers that deliver data in ultra-high precision. This equipment enables creative scientists and engineers to understand their cells in parts per million level of precision.

NOVONIX UHPC systems can be used in a number of applications, including:

Materials Evaluation

Customers working on new materials can utilize UHPC testing to understand how changes to physical properties such as morphology, particle size distribution, surface area, etc. impact the battery performance.

Cell Selection

When conducting cell selection between vendors or cell models, the ability to gather cell performance data at high accuracy in a short time is critical, especially when experiments have many dimensions (temperature, current, voltage windows, cells, etc.).

Environmental Performance Evaluation

Environmental conditions matter when testing cell performance. Learn how cells perform in extreme conditions and minimize failure mechanisms through accurate analysis of metrics such as charge endpoint capacity slippage (caused by electrolyte oxidation, transition metal dissolution, self discharge, and more).

Manufacturing Process Development

Tune process parameters on new or existing production lines – for new or existing recipes – and guarantee the repeatability of a manufacturing process to quickly gain confidence in the process.

Battery Management Optimization

Clearly understand the electrochemical response of a cell and develop charge strategies under different environmental or use conditions.
