Title:
APPARATUS, SYSTEM AND METHOD FOR DENDRITE AND ROUGHNESS SUPPRESSION IN ELECTROCHEMICAL STRUCTURES
Document Type and Number:
WIPO Patent Application WO/2019/140401
Kind Code:
A1
Abstract:
A method, and associated batteries and battery charging units, that involve inducing electric and/or magnetic fields (field-induced current) across an electrode of an electrochemical cell, such as an anode of a battery. The field and current across the electrode may be referred to herein as a transverse current as this current is typically transverse to the ionic charge current that may be applied when charging a battery. The field and current may be induced from connecting AC energy, e.g., AC current, across the electrode or at a discrete point or points of the electrode. The induced field and current may suppress dendrite growth, experienced in conventional batteries without AC energy, among other advantages.
