In addition to the upcoming battery manufacturing facility, multiple UT research labs have capabilities to produce and test full-cell batteries with capacities up to 200 mAh. Commercially relevant electrode mass loadings and cycling protocols are employed along with detailed cell performance and electrochemical property assessment.
Standard Cell Prototype Capabilities
- Centrifugal, High-Shear and Ultrasonic Mixers/Processors
- Temperature-controlled Coaters
- Hot Rolling Presses and Vacuum Ovens
- Automated Electrode Punchers
- Coin Cell and Single-Layer Pouch Cells (up to 200 mAh)
- Gloveboxes
- Crimpers
Cell Performance Evaluation
- Over 1,500 battery cycler channels with various current ranges up to 30A
- Specialized cells for advanced evaluation
- Three-electrode cells for inclusion of a reference electrode
- Optical cells for in operando visual analysis during charge/discharge, e.g. probing dendrite formation or lithium plating
- Electrochemical Impedance Spectroscopy (EIS)
- Environmental Chambers for controlled temperature evaluation at temperature extremes
