What changed

The United States Patent and Trademark Office (USPTO) has granted patent US12586873B2 for a "Conductive power rod for electrochemical cell" to South 8 Technologies, Inc. The patent describes a novel design for an electrochemical energy-storage device featuring a conductive power rod positioned within a central void formed by coiled electrodes. This rod serves a dual purpose: providing structural integrity to prevent void collapse and acting as a low-resistance current path to either the positive or negative terminal, thereby enhancing the cell's performance and stability.

While this is a patent grant and not a regulatory rule, it signifies a new technological development in the energy storage sector. Companies involved in battery manufacturing or research and development should be aware of this patented technology, as it may influence future product designs and intellectual property considerations in the field of electrochemical energy storage. No immediate compliance actions are required for regulated entities, but awareness of this patent is recommended for R&D and legal departments.

Abstract

Disclosed herein is a design for an electrochemical energy-storage device. The device includes an electrode assembly with a separator that separates a positive electrode and a negative electrode. These electrodes and separator are radially coiled about a central axis to form a central void. A positive electrode current collector is in electrical contact with the positive electrode, while a negative electrode current collector is in electrical contact with the negative electrode. A conductive power rod is positioned in the central void and provides structural support to prevent the collapse of the central void. The rod is either: (a) in electrical contact with the positive electrode current collector and provides a low-resistance current path with a positive terminal; or (b) in electrical contact with the negative electrode current collector and provides a low-resistance current path with a negative terminal. Both terminals are electrically isolated from each other.
