Description

Technical Field

[0001] The utility model relates to the technical field of battery production and processing, in particular to an airtightness detection device. Background Art

[0002] A battery is a device that converts chemical energy into electrical energy, consisting of a cup, tank, or other container, or a portion of a composite container, containing an electrolyte solution and metal electrodes to generate an electric current. Common batteries include lead-acid batteries, lithium batteries, sodium batteries, and fuel cells. Fuel cells convert the Gibbs free energy portion of a fuel's chemical energy into electrical energy through electrochemical reactions. These cells are not subject to the limitations of the Carnot cycle, resulting in high efficiency. Fuel cells use fuel and oxygen as raw materials and lack mechanical transmission components, resulting in zero noise pollution and minimal harmful emissions. Common fuel cells include hydrogen-oxygen fuel cells, solid oxide fuel cells, and methanol fuel cells. Fuel cells generally consist of electrodes, a diaphragm, and a circuit module. The diaphragm separates the oxidant and the reducing agent and conducts ions. It is a critical component of the battery, directly impacting safety and cost. Any airtightness issues with the diaphragm can severely impact battery performance and may even cause a fire. Therefore, diaphragm airtightness testing is essential during battery production. The traditional air tightness testing method relies on manual operation, which involves placing the diaphragm into the air tightness testing equipment and taking it out after testing. The overall efficiency is low and it is difficult to meet the needs of mass production. Utility Model Content
