Description
To the point
A battery calorimeter (LINSEIS IBC – 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.
The importance of the battery calorimeter: The battery calorimeter measures the amount of heat generated during electrochemical reactions in the battery.
These measurements are crucial for understanding and improving the thermal behavior and efficiency of batteries.
Areas of application: These devices are particularly important for the development of new battery types, such as lithium-ion batteries, where thermal stability and safety are of paramount importance.
They are also used for quality control and performance testing of batteries.
Thermal analysis and safety: By analyzing heat development under different operating conditions, battery calorimeters help to identify and prevent potential safety risks such as thermal runaway.
This is crucial for the safety of end-user products.
Optimizing battery performance: By accurately measuring heat generation, the internal chemistry and design of the battery can be optimized, resulting in higher energy density, better charging capacity and a longer service life.
Research and development: Battery calorimeters are used in research and development laboratories to test and evaluate new materials and technologies.
The knowledge gained is essential for progress in battery technology.

Making values visible and comparable
The IBC L91 works with two measurement plates as a calorimeter with eight Heat Flux sensors and ten temperature sensors in the smallest configuration (80 mm x 80 mm).
The layout gives the ability to realize stable ambient conditions and minimum losses for each sample type. The measurement cell is avaiable in 80 mm x 80 mm, 300 mm x 300 mm, 600 mm x 600 mm as well as customzed layout to our customers needs.
Furthermore the open access design gives the ability to run the charging and discharging process with every charger, Load or power supply. Measurement data and protocolls can be imported to Linseis Platinum Software for combined evaluation and correlation of electrical and thermal behavior of batteries.
Besides the Plate design also adapters for round cells (18650, 14500 …) as well as coin cells are avaiable.
Applications
Linseis IBC gives the ability to deeply investigate batteries
- Under different temperature conditions
- For aging behavior
- For efficiency level of cell and electronics
- For various battery types
- For various cell formats (pouch, coin, round, boxed …)
- For phase changes during usage
Application example:
Heat flow across the capacity of a 1-cell Li-ion standard battery at different charge and discharge currents. This allows conclusions to be drawn about the stress on a battery during charging or discharging. For example, the cell voltage, charge and discharge current, and the correlating heat flow from the sample can be displayed. In addition, other relevant information such as the transferred charging and discharging power and temperature of the battery can be displayed, analyzed and documented.
Application example:
Heat flow over the capacity of a 1-cell Li-ion standard battery at different charge and discharge currents. This allows differences in the efficiency of various charging parameters to be displayed depending on the capacity of a battery. What is striking here, for example, is the different residual capacity depending on the different discharge parameters. A significant increase in heat flow at higher charging and discharging currents is also evident.
