Differential scanning calorimeter Coin Cell DSC

high-temperatureisothermalhigh-sensitivity

Overview
The Coin Cell Differential Scanning Calorimeter (Coin Cell DSC) performs direct thermal analysis of fully assembled coin cells (e.g. 2032 format) without disassembly, identifying onset temperature, heat of reaction and energy release to support battery safety and performance assessments.

Key capabilities

• Direct testing of fully assembled 2032 coin cells without teardown
• Rapid detection of onset temperature, reaction mechanisms and heat of reaction
• Simultaneous thermal and electrochemical signal capture (temperature, heat flow, voltage monitoring)
• Wide operational range enabling safety characterization from −80 °C to 600 °C (dependent on cooling system)
• Compatible with Evolved Gas Analysis (EGA) for off‑gas identification

Advanced features

• High‑sensitivity sensor for precise onset and heat flow measurement
• Coin cell capsule design maintaining sensor contact up to cell failure
• Voltage monitoring interface for state‑of‑charge and internal short analysis
• EGA compatibility with MS, FTIR or GC‑MS
• App‑style color touchscreen for local control

Testing modes & applications

• Scanning mode — assess thermal abuse, degradation, onset temperature and cross‑reactions
• Isothermal mode — monitor heat flow during SEI formation, charge/discharge, overcharge and overdischarge
• Early‑stage formulation safety screening with minimal material and faster turnaround

Coin cell capsules & pan options

• Standard coin cell capsules — preserve thermal signal across sample range
• Cycling capsules — optimized for isothermal cycling (ECA‑enabled cycling capsule limited in temperature with ECA)
• 20 mm aluminum pans — for material samples and supporting measurements

Data & software

• Controlled and analyzed with TRIOS software with built‑in coin cell templates
• Intuitive visualization, automated analysis and report generation
• Data export in JSON for LIMS integration and networked access

Resources and outputs

• Compatible with EGA instrumentation for off‑gas characterization and mechanistic studies
• Interfaces to external electrochemical equipment: voltage monitors, battery cyclers, potentiostats
