What Causes Delamination in Cross-Laminated Timber (CLT) …
What Causes Delamination in Cross-Laminated Timber (CLT)? Basically, any force applied to the bonding area can cause delamination if the adhesive is not strong enough. Delamination can be caused by service loads, residual loads, self-weight loads, or (most commonly) the load induced due to the shrinkage of the wood.

1. Introduction. More than 40 years after production of the first commercial lithium cell by Sanyo in 1970s, [1] the lithium-ion battery (LIB) technology has become a main contributor for the storage devices in the field of rechargeable batteries.LIB technology needs further improvement in terms of fast charging capability which can reduce the …
Overcome the Challenges in Winding Flexible Packaging Film
Tightly wound rolls cause problems of their own. They can create blocking-defect issues where the layers fuse or adhere. When winding extensible film on thin-wall cores, winding hard rolls can cause the cores to collapse. This can cause problems with shaft removal or with inserting the shaft or chucks on the subsequent unwinding operation.
Nondestructive Defect Detection in Battery Pouch Cells: A …
In battery cell production, especially when electrode rolls are transported between production sites, such defects are a real possibility. The position of the defects is different on each sheet, so the depth of the respective sheet can be clearly identified by subsequent examinations with the nondestructive methods.

Detection of Manufacturing Defects in Lithium-Ion Batteries …
Realising an ideal lithium-ion battery (LIB) cell characterised by entirely homogeneous physical properties poses a significant, if not an impossible, challenge in LIB production. Even the slightest deviation in a process parameter in its production leads to inhomogeneities and causes a deviation in performance parameters of LIBs within the …
Laser Welding in Battery Production | VITRONIC
Frequent shutdowns to analyze and eliminate the causes of defects are expensive, as mentioned above. This is not how to run a highly automated production line. The VIRO WSM inspection system therefore tackles the problem at an earlier stage: It monitors the welding process in real time and immediately detects and signals deviations.
