METHOD FOR MANUFACTURING ELECTRICAL STORAGE DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18510653 titled 'METHOD FOR MANUFACTURING ELECTRICAL STORAGE DEVICE

The manufacture method disclosed herein is a method for manufacturing an electrical storage device, including a step of preparing an outer case in which a peripheral part of an opening is a flat surface, and a lid assembly obtained by integral molding of a lid, a terminal member, and an insulating member, a step of attaching the lid assembly to the opening of the outer case, and a step of irradiating the boundary of the peripheral part and an outer edge part with laser light. The lid assembly is placed so that an inclined part will become thinner from the outer surface toward the boundary with the outer case, and the outer surface of the lid is placed at a higher place than the peripheral part of the opening, and the inner surface of the lid is placed at a lower place than the peripheral part of the opening.

• Lid assembly obtained by integral molding of a lid, a terminal member, and an insulating member
• Laser light irradiation of the boundary of the peripheral part and an outer edge part
• Outer case with a flat surface peripheral part of an opening
• Lid assembly designed with a thinner inclined part towards the outer case boundary
• Outer surface of the lid placed higher than the peripheral part of the opening

Potential Applications: - Manufacturing of electrical storage devices - Battery production industry - Electronics manufacturing sector

Problems Solved: - Efficient assembly of lid assembly to outer case - Ensuring proper sealing of the electrical storage device - Enhancing the structural integrity of the device

Benefits: - Improved manufacturing process - Enhanced product quality and durability - Cost-effective production method

Commercial Applications: Title: Innovative Method for Electrical Storage Device Manufacturing This technology can revolutionize the battery production industry by streamlining the manufacturing process and improving product quality. It can also have significant implications in the electronics manufacturing sector, leading to more efficient and reliable electrical storage devices.

Questions about Electrical Storage Device Manufacturing: 1. How does the lid assembly contribute to the overall structural integrity of the electrical storage device? 2. What are the advantages of using laser light irradiation in the manufacturing process of these devices?
