How the Skin Effect Quietly Shapes Lithium Battery Performance?

Leave a Comment / Lithium Ion Batteries / adminbackups

In the realm of electrical engineering, the “skin effect” describes a peculiar phenomenon where high frequency alternating current (AC) tends to flow predominantly along the surface of a conductor, rather than distributing evenly across its entire cross-section. Imagine a crowded highway where, at high speeds, traffic jams up the inner lanes, forcing cars to the
