Proposed are a system and a method for pressurizing an all-solid-state secondary battery at high temperature. More particularly, proposed are a system and a method for pressurizing an all-solid-state secondary battery at high temperature, in which a pre-process of high-temperature pressurization for maximizing a contact interface between a solid electrolyte and an active material and minimizing interfacial resistance is automated in such a manner that the fed secondary battery is automatically packed through a vacuum sealing unit and then pressurized at high temperature, thereby shortening a tact time and thus increasing process efficiency.

Various arrangements for compressing a cylindrical battery cell are presented herein. The cylindrical battery cell may be wrapped in a buffer material. The buffer material may then be compressed using a compression mechanism. The buffer material may uniformly distribute pressure applied to the buffer material to a curved sidewall of the cylindrical battery cell.

The present invention relates to an apparatus and a method of folding a pouch case of a battery cell, and more particularly, to an apparatus and a method of folding a pouch case of a battery cell capable of preventing a meandering in a folding process and reducing non-uniformity of a folding amount by forming a pre-folding line on a pouch wing and folding the pouch wing on the basis of the pre-folding line.

Systems and methods for the roll-to-roll deposition of electrochemical cell components and other articles are described.

To solve the above problem, a method for manufacturing an electrode lead according to an embodiment of the present invention includes: a step of manufacturing each of a first electrode lead and a second electrode lead by cutting a metal plate; a step of applying an adhesive to at least one of one end of the first electrode lead or the other end of the second electrode lead; a step of forming a lead stack by bonding the one end of the first electrode lead and the other end of the second electrode lead to each other; a step of placing the lead stack on a die; and a step of applying heat and pressure to a connection portion of the lead stack, in which the first electrode lead and the second electrode lead are connected to each other, by using a pressing device.

Discussed is a a process automation system including: a cell transferor configured to transfer battery cells; a cell inspector configured to measure an open circuit voltage of each battery cell in units of a preset number of battery cells and to sort out qualified battery cells and defective battery cells; a frame transferor configured to transfer module frames of a battery module to insert the qualified battery cells; a cell discharger configured to load and discharge the defective battery cells; and a gripper configured to pick up one or more battery cells from any one device among the cell transferor, the cell inspector, the frame transferor, and the cell discharger, and transport the one or more battery cells to another device.

The application provides a battery cell, a manufacturing method and a manufacturing system therefor, a battery and an electric device. The battery cell in one embodiment of the application includes a casing having an opening and provided with a pressure relief mechanism which is actuated to relieve an internal pressure or temperature of the battery cell when the internal pressure or temperature reaches a threshold value; an electrode assembly accommodated in the casing, and including a body portion and a tab portion protruding therefrom; and a cover assembly for covering the opening. A first recessed portion is formed on one side, abutting against the body portion and facing the electrode assembly, of the cover assembly. The cover assembly is provided with at least one first channel. The first channel can reduce the gas accumulated between the electrode assembly and the cover assembly, thereby reducing the safety risk.
