High Precision Battery Cyclers

Novonix specializes in developing battery testing equipment with a strong focus on the use of High Precision Coulometry for reliable lifetime evaluation of lithium-ion cells.

Life time prediction, lithium plating or impact of electrolyte additives. Novonix High Precision Coulometry equipment allows long-term performance prediction in short-term experiments. Coulombic efficiency with a precision of 20 ppm and accuracy of 50 ppm make this equipment the market leader in High Precision Coulometry.

Novonix has expertise in materials and cell testing, focusing strongly on the use of High Precision Coulometry for lifetime evaluation of lithium-ion cells.

Recent developments include high precision chargers, which are able to measure the coulombic efficiency of cells to less than 20 ppm noise and to 50 ppm accuracy.

Novonix’s High Precision Charger provides industry-leading low noise and high accuracy source and measurement electronics, catered to making precision measurements of coulombic efficiency. 

Precise measurements of the coulombic efficiency of a cell using the proper equipment has been shown to have enormous benefits to battery R&D projects, allowing researchers to characterize lifetime and evaluate the impact of small changes to battery design on long-term performance in short-term experiments.

The High Precision Charger can be used with a temperature controlled cell to measure coulombic efficiency with a precision of 20ppm and accuracy of 50ppm. Novonix also supplies Thermal Control Chambers which can be used to control the temperature of a cell.

During charge and discharge over the full load voltage range of 0-5V, the system functions in constant current or constant voltage mode.

Coulombic Efficiency vs Time
This image demonstrates how the precise measurements of coulombic efficiency can predict cell lifetime, which have little capacity loss until complete failure.

Colombic Efficiency vs Cycle No.
This image demonstrates how the coulombic efficiency can also predict the long term performance of cells that show gradual capacity loss with cycling.
