Waters Corporation has launched the TA Instruments™ Coin Cell Differential Scanning Calorimeter (DSC), a new tool built to change how battery safety testing is done. Designed specifically for battery scientists, the Coin Cell DSC lets researchers test fully assembled coin cells directly, cutting out the long, labor-intensive prep steps while delivering faster and more detailed insights into battery safety and performance.
This is the only DSC on the market that captures multidimensional data, allowing researchers to collect thermal data from the entire cell while simultaneously measuring evolved gas and electrochemical performance.
By adding voltage monitoring and charge/discharge capability, the system helps scientists directly link thermal behavior with electrochemical activity. This makes it easier to spot early signs of thermal runaway and battery failure. The system can also be connected to MS, FTIR, or GC-MS for direct analysis of off-gas composition.
A key innovation is the unique capsule design that removes the need for tedious cell teardown. This reduces average sample preparation time by more than 90 percent while keeping the sample intact and preserving its integrity. The result is significantly faster data generation without sacrificing accuracy.
The Coin Cell DSC brings together advanced temperature performance, streamlined workflows, and multidimensional data capture in one platform.
With an industry-leading temperature range of –80 °C to 600 °C, it supports comprehensive analysis of both low- and high-temperature behavior, opening up new possibilities for development and QA/QC applications.
Traditional battery safety testing methods like accelerating rate calorimetry (ARC) are typically used late in the research process, require large cells, need specialized facilities, and take a long time to run.
The Coin Cell DSC, by contrast, lets researchers evaluate intact coin cells earlier and faster, making development more efficient and helping reduce risk.
Leadership Comments
“The Coin Cell DSC represents a significant advancement in battery thermal analysis,” said Yu Cheng, Vice President, Research and Development and Product Solutions, Materials Sciences, Waters Corporation. “Simultaneously capturing thermal, evolved gas, and electrochemical data is not only faster, but also correlates data from the same sample for more exacting insights earlier in development. With its broad temperature range and streamlined workflows, the system is designed to reduce experimental complexity while outperforming current approaches.”
“The battery industry has long needed a solution that bridges the gap between materials thermal analysis and full-cell DSC testing. This technology enables the evaluation of full-cell thermal stability by incorporating gas analysis and electrochemical data—capabilities that are essential for advancing early-stage battery safety research,” said Shirley Meng, Professor, Pritzker School of Molecular Engineering, University of Chicago and Director, Energy Storage Research Alliance (ESRA).
The Waters TA Instruments Coin Cell DSC is available for order now, with shipments expected to begin in August 2026.
