Electrochemical Corrosion Kinetics across Dissimilar Conductor Interfaces
Electrochemical corrosion kinetics across dissimilar conductor interfaces accelerate through moisture condensation, demanding perimeter sealing and barrier plating.
Non-Destructive CT Scanning
Meaning
Imaging techniques use x-rays to create three dimensional representations of the internal structure of an object without causing any physical damage. Non-destructive ct scanning allows engineers to inspect the layers of a battery cell for defects such as electrode misalignment or the presence of foreign particles. This process provides a clear view of the interior of a finished cell that would be impossible to see with any other method.
Quality Control
Production lines use this technology to identify manufacturing errors before the cells are assembled into packs. By employing non-destructive ct scanning, a factory can catch issues like tab folding or electrolyte dry spots that might lead to early failure. This high resolution inspection ensures that only perfect cells reach the customer.
Failure Investigation
Forensic analysis of batteries that have degraded prematurely often starts with a digital look inside the casing. Because non-destructive ct scanning does not require cutting the cell open, it preserves the evidence of internal shorts or lithium plating. This allows researchers to see the exact state of the materials as they were during the failure.
R and D Tool
Development of new chemistries and cell designs is accelerated by the ability to see how they change over time. Scientists use non-destructive ct scanning to observe the mechanical effects of cycle aging, such as the cracking of particles or the delamination of the active material. These insights lead to more durable designs and a better understanding of the physical limits of the technology.
The data helps in refining the mathematical models of cell behavior by providing real world measurements of the internal geometry after hundreds of cycles.
