In this article, we will take a look at the solutions ideal for tension, puncture, and peel testing of those batteries. A test solution for the lithium-ion battery industry would typically consist of material testing machine, fitted with a high accuracy load cell, analytical software and grips suitable for securing the battery during the test.
In this article, we will go through the grip recommendations to the most common tests types within lithium-ion battery testing. These are tension, puncture, and peel.
Various battery test methods exist, including crush and puncture, but the two that manufacturers prioritize are the short circuit and temperature cycling tests. The purpose of the short circuit test is to assess how the battery responds to internal short circuits. If the battery’s safety mechanisms prevent thermal runaway, it will pass.
Using a footswitch for actuation of the pneumatic grips frees the hands of the operator so securing of the battery separator is fast and efficient. To ensure stability and efficiency in the puncture test of the battery separator, the materials tester combined with a pneumatic puncture test fixture is the ideal solution.
Due to the potentially hazardous nature of lithium batteries, these lithium-ion battery testing standards assure carriers that relevant products are safe to transport. Central to these standards is temperature cycling. These tests expose lithium batteries from -40C to 75C using 30-minute transitions.
During the thermal test, batteries are placed in a testing chamber, and the temperature is raised at 5C per minute to a maximum of 130C. These tests reveal how the battery responds to different temperatures. During the temperature cycling test, the battery is placed in a chamber where the temperature is decreased from 85C to -40C at 1C per minute.
