What changed

The United States Patent and Trademark Office (USPTO) has granted patent US12586876B2 for a novel method of manufacturing secondary battery terminals. The patent, assigned to PRIME PLANET ENERGY & SOLUTIONS, INC., describes a process that enhances injunction strength by joining two different metal members using ultrasonic pressure contact. This method involves fitting a second member's flange into a concave part of a first member and applying ultrasonic vibrations under pressure to create a secure bond.

This patent grant is primarily an intellectual property event and does not impose new regulatory obligations on manufacturers. However, it signifies an advancement in battery component technology. Companies involved in battery manufacturing, particularly those seeking to improve terminal strength and assembly efficiency, may find this patent relevant for competitive analysis or potential licensing discussions. No immediate compliance actions are required for regulated entities based on this patent grant.

Abstract

Provided is a method for manufacturing an electrode terminal formed of different kinds of metals excellent injunction strength. The manufacturing method of a terminal herein disclosed includes the following steps of: preparing a first member and a second member each made of a metal and forming the terminal, with the first member being formed in a sheet shape and having at one surface thereof a concave part for allowing a part of the second member to be fitted therein, and with the second member having a flange part to be accommodated in the concave part; and fixing the first member and the second member to each other by ultrasonic pressure contact, with the ultrasonic pressure contact being performed by applying an ultrasonic wave vibration while applying a pressure in a direction of stacking of the first member and the second member in a state where the flange part of the second member is arranged in the concave part of the first member, thereby extending the flange part, and bringing a part of the extended flange part into pressure contact with an inner wall surface of the concave part.
