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. With this expertise, Novonix was established to develop battery testing systems specifically catered to precision measurements of coulombic efficiency. Novonix’s high precision charger systems have been shown to measure the coulombic efficiency of cells to typically less than 10 ppm precision and 50 ppm accuracy. Novonix offers both testing services and equipment sales to help customers get the most out of their use of high precision coulometry techniques.
Many recent journal publications from Dr. Dahn’s and other’s research groups have been centered around the use of High Precision Coulometry as a tool in evaluating lifetime performance of Li-ion cells and evaluating the impact of electrolyte additives in short-term experiments that accurately represent the long-term performance.
