METHOD FOR PRODUCING POWER STORAGE DEVICE AND POWER STORAGE DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18464265 titled 'METHOD FOR PRODUCING POWER STORAGE DEVICE AND POWER STORAGE DEVICE

Simplified Explanation

The patent application describes a method for producing a power storage device by laser-welding the opening portion of a case body and a peripheral portion of a lid over their entire circumference, with the lid assembly closing the opening portion of the case body. The resin member used in the device has an outer surface with a scattered light-reached surface that allows scattered light of a laser beam to directly reach it. Additionally, at least a part of the scattered light-reached surface includes a smoothed region with a surface roughness of 0.6 μm or less.

• Laser-welding method for producing a power storage device

Original Abstract Submitted

A method for producing a power storage device includes closing an opening portion of a case body with a lid of a lid assembly, and laser-welding the opening portion of the case body and a peripheral portion of the lid over their entire circumference. A resin member has an outer surface including a scattered light-reached surface to which scattered light of a laser beam directly reaches, at least a part of the scattered light-reached surface including a smoothed region having a surface roughness of 0.6 μm or less.
