Overview
The Coin Cell Differential Scanning Calorimeter (Coin Cell DSC) performs direct thermal analysis of fully assembled 2032-format coin cells without teardown. It identifies onset temperature, energy release and heat of reaction, and supports combined thermal and electrochemical evaluation for battery safety and performance testing.

Key capabilities

• Direct testing of fully assembled 2032 coin cells without disassembly
• Rapid detection of onset temperature, reaction mechanisms, heat of reaction and off‑gas indications
• Simultaneous capture of thermal and electrochemical signals for safety and performance analysis
• Complete characterization across −80 °C to 600 °C (depending on cooling system)

Features

• Highly sensitive sensor for precise onset temperature and heat flow measurement
• Wide temperature range: −80 °C to 600 °C (system dependent)
• Coin cell capsule maintains sensor contact through cell failure
• Evolved Gas Analysis (EGA) compatibility with MS, FTIR or GC‑MS
• Voltage monitoring for state‑of‑charge and short‑circuit analysis
• Color app‑style touch screen for instrument control

Coin cell capsule

• Compatible with 2032 and any 20 mm diameter coin cell
• Standard capsules preserve thermal signal across the sample range
• Cycling capsules optimize heat flow during isothermal cycling
• 20 mm aluminum pans available for material samples

Dual testing modes

• Scanning mode: assesses thermal abuse, degradation, onset temperature, heat of reaction and material cross‑reactions
• Isothermal mode: evaluates heat flow during SEI formation, charge/discharge, overcharge and overdischarge

Evolved Gas Analysis (EGA)

• Compatible techniques: Mass Spectrometry (MS), Fourier Transform Infrared Spectroscopy (FTIR), Gas Chromatography–Mass Spectrometry (GC‑MS)

Electrochemical connection

• Supports connection to voltage monitoring devices to capture electrical signals
