IBC - Isothermal Battery Calorimeter

Battery calorimeters measure heat development in batteries. LINSEIS offers modular IBCs for research and quality control.

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 measurement is referred to as “heat of reaction” and is an important indicator of a battery’s performance.

The heat of reaction is the difference between the enthalpy (heat content) of the reactants and the products of a chemical reaction.

Battery calorimeters are used in research and development to evaluate new battery chemistries and optimize the design of existing batteries.

They are also used in the manufacturing process to ensure that the batteries meet performance and safety standards.

LINSEIS offers a modular Isothermal Battery Calorimeter (IBC) for the thermal monitoring of batteries.

It consists of a variable number of almost identical components and enables the investigation of a wide range of battery cell sizes.
The geometry of the modules is also easily scalable.

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.

Software

Making values visible and comparable

The IBC works with two measuring plates as a calorimeter with eight heat flow sensors and ten temperature sensors in the smallest configuration (80mm x 80mm).

The layout enables stable measuring conditions and minimal losses for each sample type.
The measuring cell is available in the sizes 80 mm x 80 mm, 250 mm x 250 mm, 400 mm x 250 mm as well as in customized versions.

In addition, the open design allows the charging and discharging process to be carried out with any charger, charge or power supply.
Measurement data and logs can be imported into the Linseis Platinum software for combined evaluation and correlation of the electrical and thermal behavior of batteries.

In addition to the plate design, adapters for round cells (18650, 14500 …) and button cells are also available.
