Diagnosis of Electrochemical Degradation in a Large-Format NCM Pouch Cell under Over-Discharge Using EIS and Acoustic Emission

Over-discharge of large-format lithium-ion cells can cause electrochemical and mechanical degradation, leading to safety concerns. This study investigated a 67 Ah NCM pouch cell using electrochemical impedance spectroscopy (EIS), acoustic emission (AE), and X-ray computed tomogra...

Development of a Safety Assessment Framework for Fixed-Type Offshore Wind Power Facilities Using AHP-FMEA Methodology

Fixed-type offshore wind power facilities operate under harsh marine conditions—salinity, corrosion, combined wave and current loading, and severe access restrictions—that increase the likelihood of component failure while making periodic inspection and maintenance difficult and...

A Terrain-Structured Dual-Pareto Framework for Saemangeum Wind-Farm Re-Planning Under Measured Wind, Wake-Loss, and Cost-Chain Constraints

Wind-farm re-planning must reconcile wind resources, wake interactions, cable routing, foundation and installation requirements, grid access, land/water-use cost, and operation and maintenance. This study develops a terrain-structured dual-Pareto framework for the Saemangeum comp...
