Battery Cell Fabrication and Testing

RISE Battery lab is equipped with facilities to produce full-cell battery prototypes using the same processes used in the battery industry. In this facility, we can assist in evaluating and qualifying new battery materials, electrolytes, binders, and other components at two stages of scale-up: lab-scale coin cell and small pouch cell prototypes (0.3-1 Ah).

Our teams of material chemists, electrochemists, and engineers have robust experience in all aspects of the battery cell fabrication process. Commercially accepted methods and protocols are used during cell fabrication for benchmarking the newly developed materials with the standard battery components.

Materials performance parameters such as specific capacity, voltage stability, long-term durability, and impedance are tested at coin cell level. The parameters such as electrode mass loading, electrode density, porosity, and other cell engineering parameters are evaluated at pouch cell level to predict the commercial viability.

RISE has state-of-the-art battery cell characterization facilities with multiple battery cyclers covering various current ranges up to 60 A. We can test all kinds of performance metrics such as specific capacity, voltage window, maximum charge and discharge current, state of health, specific energy and power, cell impedance, and so on. Cycle-life testing determines the cell's lifespan by subjecting it to repetitive charge and discharge cycles.

Our testing facility is adapted for all cell formats, including coin/Swagelok^TM cells and commercial cylindrical and pouch cells. We also have precision potentiostats for advanced-level cell evaluation in three-electrode configuration (Swagelok and pouch cell), in operando analysis such as RAMAN and electrochemical impedance spectroscopy. We also have atmospheric chambers to do the environmental test at different temperatures and humidity conditions. These tests help ensure that batteries can operate reliably in different environments.
