NEWARE Battery Puncture and Crush Tester 6012C

What is crushing cells test？

Crushing cells test is a test method used to evaluate the safety and structural integrity of batteries when subjected to mechanical squeezing or compression. This test simulates the squeezing conditions that batteries may experience during actual use, such as vehicle collisions, drops, or other forms of mechanical impact. The purpose of the extrusion test is to ensure that the battery does not experience short circuits, fires, or explosions when subjected to such mechanical stress, thus ensuring user safety.

Crushing cells test typically involves applying a specific force to the battery using specialized equipment to induce deformation. During the test, parameters such as voltage, current, and temperature of the battery are monitored to evaluate its performance changes during the extrusion process. Based on the battery's response, it can be determined whether the battery's safety performance meets the required standards.

In battery testing standards, Crushing cells test is an important aspect as it reveals the thermal runaway characteristics and mechanisms of batteries under mechanical squeezing, as well as the influence of separator materials on triggering thermal runaway during extrusion. Through these tests, researchers and manufacturers can better understand the safety performance of batteries and take appropriate measures to improve their safety.

How to use NEWARE battery puncture and crush tester for Crushing cells test?

The battery extrusion and puncture integrated machine is suitable for simulating situations where various types of batteries undergo squeezing and puncturing during use, transportation, storage, or handling of household waste.

The rules for the extrusion test direction are as follows.

1.For cylindrical batteries, the longitudinal axis of the battery should be parallel to the two plates of the extrusion device during the battery extrusion.

2.For square and pouch batteries, only the width surface of the battery should be subjected to squeezing.

3.For coin or button-shaped batteries, the battery should be squeezed with its upper and lower surfaces parallel to the plates.

Please ensure that each battery is only subjected to one extrusion, and it is considered qualified if the battery does not explode or catch fire.

What issues should be taken into account during crushing cells test?

When conducting Crushing cells test, several important considerations should be taken into account. Here are the key points to keep in mind.

Safety precautions: Ensure that proper safety measures are in place, including personal protective equipment (PPE) for the testing personnel. This may include safety glasses, gloves, lab coats, and other necessary gear to protect against potential hazards.

Test environment: Conduct the Crushing cells test in a controlled environment, such as a testing laboratory or a designated area with proper ventilation. This helps mitigate any potential risks associated with gas emissions or thermal events during the test.

Equipment calibration: Before conducting the test, calibrate and verify the accuracy of the testing equipment, including the force sensors, displacement measurement devices, and temperature sensors. This ensures reliable and accurate test results.

Test parameters: Define and adhere to the specific test parameters, such as the applied force or pressure, deformation rate, and temperature conditions. These parameters should be based on relevant standards or specifications, ensuring consistency and comparability of the test results.

Sample preparation: Prepare the battery samples following the recommended guidelines, including the size, shape, and orientation of the battery during testing. Ensure that the samples are representative of the actual batteries used in practical applications.

Data monitoring: Continuously monitor and record key parameters during the extrusion test, such as voltage, current, temperature, and deformation. This allows for a comprehensive analysis of the battery's behavior and performance under mechanical stress.

Failure analysis: In the event of a battery failure or thermal event during the extrusion test, conduct a thorough analysis to understand the cause and mechanisms involved. This analysis helps identify potential vulnerabilities or design flaws that may compromise the safety of the battery.

Reporting and documentation: Document all test procedures, observations, and results accurately and comprehensively. This documentation serves as a reference for future analyses, comparisons, and improvements in battery design and safety.

By addressing these considerations, researchers and manufacturers can conduct Crushing cells test effectively and obtain valuable insights into the safety and structural integrity of batteries under mechanical stress.
