What changed

This document is a published patent application (US20260088469A1) filed by FARASIS ENERGY (GANZHOU) CO., LTD. It describes a novel riveting structure for cell posts designed to improve battery performance. The invention aims to eliminate weld protrusions by fixing the post to the inner surface of an external terminal, allowing it to penetrate through the lower shell and be riveted to the current collector. This method is intended to create a smoother outer surface on the external terminal, facilitating a tighter fit with the busbar and thereby improving current stability.

As this is a patent application, it does not impose direct regulatory obligations or compliance deadlines on entities. However, companies involved in battery manufacturing, particularly those focused on energy storage solutions, may find the disclosed technology relevant for their research and development or intellectual property strategies. The filing date was November 29, 2024, with a publication date of March 26, 2026.

Abstract

Disclosed is a riveting structure for cell posts. A cell comprises a lower shell, an external terminal and a current collector, the external terminal is arranged on an outer side of the lower shell, and the current collector is arranged on an inner side of the lower shell; and the external terminal has an inner surface facing the lower shell and an outer surface backing on to the lower shell. In the invention, the post is fixed to the inner surface of the external terminal and then penetrates through the first through-hole in the lower shell to be riveted to the current collector. In this way, a weld protrusion generated by welding the post to the outer surface of the external terminal is avoided, and the outer surface of the external terminal is smoother and can be in tighter fit with the busbar, thus improving the current stability.
