Description

Our battery calorimeter (LINSEIS IBC L91 – Isothermal Battery Calorimeter) is a device for measuring the heat generated by a battery during charging and discharging.

This released heat is an important indicator of the performance and current operating status of a cell or battery pack. Depending on the chemical composition, design and size of the cell, but also depending on the current state of charge and the ambient conditions, the amount of heat generated can vary.

• Why battery calorimetry matters
  Battery calorimeters precisely measure the heat generated during electrochemical reactions – a key parameter for evaluating thermal behavior, safety and efficiency of battery cells and modules.
   
• Targeted applications
  These systems are essential for the development and qualification of advanced battery technologies such as lithium-ion, solid-state and next-generation chemistries. They are also widely used in quality assurance, abuse testing and safety validation for commercial and automotive batteries.
   
• Thermal Analysis for safety
  By analyzing heat generation under defined charge/discharge conditions or extreme scenarios, battery calorimeters enable the detection of early-stage thermal risks, including thermal runaway, cell venting or reaction onset temperatures – all critical for regulatory compliance and end-user safety.
   
• Optimizing battery performance
  Accurate thermal data provides deep insight into internal cell chemistry and design parameters. This allows for the optimization of energy density, fast-charging behavior, cycle life and overall system stability.
   
• Enabling Innovation in R&D
  Battery calorimeters are indispensable tools in research and development – from evaluating new materials and binders to testing full-cell assemblies under realistic thermal profiles. The insights gained drive innovation across the energy storage industry.
