A lead tab for a secondary battery is an electrode terminal connected to the positive and negative cells of the secondary battery. A secondary battery consists of a thin plate-shaped anode and cathode electrode plates and a separator. An electrode terminal is necessary to move the electrons of the electrode plate to the outside or inject them back into the electrode plate.

A lead tab for a secondary battery, like an electrode plate, is a component that needs to be lightweight and thin, and in particular, its surface treatment is very important. Physical defects, including dents, scratches, and presses, that occur on the surface greatly affect the sealability of secondary batteries. In addition, chemical defects such as foreign substances or stains may also have a fatal effect on the performance of the secondary battery itself.

As technology development and demand for mobile devices increase, the demand for secondary batteries as an energy source is rapidly increasing. It is widely used.

Secondary batteries, depending on the shape of the battery case, include a cylindrical battery or a prismatic battery in which a jelly-roll is embedded in a cylindrical or prismatic metal can, and a pouch-type battery in which the jelly-roll is embedded in a pouch-type case of an aluminum laminate sheet. classified as

Among these secondary batteries, the pouch-type battery has a structure in which a panel to which a lead protruding to the outside is attached is sealed in an electrolyte tube filled with electrolyte. Typically, the lead is made of a metal plate such as aluminum, which is an electrical conductor, and the electrolyte tube is made of a synthetic resin tube. there is

In order to solve this problem, a lead film having the property of adhering well to both metal and synthetic resin materials is first welded to the lead, and then the lead tab with the lead film is placed at the inlet of the electrolyte tube and the inlet is opened. A battery is manufactured by a method of welding, etc.

In addition, secondary battery parts are generally mass-produced by automated production facilities, and in the case of lead tabs, lead films are welded at regular intervals to a metal strip-shaped lead strap with a certain width. It is wound on a reel and provided to the battery production process, and is cut into pieces by an automatic battery manufacturing machine and used as a lead tab of the battery.

The secondary battery manufactured in this way inspects the external shape of the battery cell through vision inspection to detect the size and defect of the battery cell. At this time, the bubble between the metal sheet and the sealant film in the lead tab part of the manufactured battery cell expands as the temperature rises during the use of the battery, causing leakage or explosion, so it should be thoroughly inspected.

In addition, even if the above-described physical or chemical defect occurs in a very fine size, the lifespan of the secondary battery may be shortened and reliability may be adversely affected.

It is very difficult to accurately detect microscopic physical and chemical defects in surface inspection. Physical defects vary in shape and location. In addition, chemical defects have various chemical constituents that form foreign substances or stains. As such, defects occurring in size, shape, and chemical composition that cannot be specified in advance should be able to be detected by an inspection method of a specific structure.
