Adhesion test in batteries

Adhesion tests are crucial to ensure that the electrode coating material does not crack or detach from the current collector during use. These tests help evaluate the adhesion strength and lifespan of electrodes, which is important to prevent battery failures. Common tests include 90° peel tests and 180° peel tests.

Purpose

One of the most common causes of battery failures is the cracking or detachment of the electrode coating material from the current collector.

This problem is usually caused by mechanical stress during use and the constant charging and discharging of the battery. It is crucial to evaluate the adhesion strength of electrodes before and after accelerated aging to ensure that a battery does not fail prematurely.

For new designs, it is important to understand how electrode adhesion is affected by different binders and elements. The two most common tests to characterize adhesive properties and monitor production materials for electrodes are 90° peel tests and 180° peel tests.

Method

Adhesion peeling tests based on the standards ISO 8510-1, ISO 8510-2, ASTM D3359-23, ASTM D6862 and ASTM D903, F88/F88M

Free fall-testing involves dropping the battery from a certain height onto a hardened surface.

Climate testing of batteries – Battery testing

Climate testing of batteries is performed to evaluate or determine that a battery can operate in and handle different climates. These tests are essential to ensure battery performance and to fulfil specific requirements for the battery's intended use.

Vibration testing of batteries – Battery testing

Vibration testing of batteries is carried out to ensure that batteries can withstand the vibrations they may be subjected to in different applications. This is important to guarantee the safety and functionality of the battery. In some cases, it is necessary to fulfil national and international requirements.

Immersion test of batteries – battery testing

To immersion test batteries means immersing a battery in a liquid, and then evaluating how it is affected. After test, any damage to the battery is examined. This is important to ensure that batteries have sufficient protection against external impact.

Fire testing of batteries - battery testing

The purpose of fire testing of batteries is to investigate the safety and performance of a battery under various conditions. This is a kind of safety-critical testing that often leads to severe fire and, in some cases, explosion.
