Compression Test for Structural Materials of Lithium-Ion Batteries

 

 

Since lithium-ion batteries are light and small, they are used in a wide variety of products, from mobile electronic devices such as cellular phones and notebook PCs to electric cars and hybrid cars. Their inner structural materials are subjected to external force during production processes and to pressure during use. Therefore, evaluation of strength of each structural material is important to maintain consistent quality

Evaluation of Temperature-Dependent Strength Properties of Lithium-Ion battery separator by piercing and Tensile Testing

Because Lithium-ion batteries can sometimes become unstable due to short-circuit, over charging and discharging, impact, etc., a variety of protection mechanisms are incorporated at the battery component level to ensure safety. 

Of these components parts, the lithium-ion battery separator prevents contact between the positive and negative electrodes, therefore high mechanical strength is required.
