AI Technical Summary
Technical Problem
The existing gasket structure of battery cells is prone to melting at high temperatures, which can lead to blockage of the venting channels and potentially cause battery cell explosions or further thermal runaway.
Method used
The structure employs an X-shaped connection structure and a strip plate gasket structure, using high-temperature resistant materials such as silicone rubber or aluminum alloy, and is coated with a corrosion-resistant ceramic coating to ensure structural integrity and unobstructed venting channels in the event of thermal runaway.
Benefits of technology
It maintains its supporting function at high temperatures, prevents blockage of the exhaust channel, avoids cell explosion or further thermal runaway, and improves exhaust capacity by 52.5%.

Abstract
The utility model belongs to the technical field of batteries, and provides a gasket structure, a battery cell, a battery pack and an electric car, the gasket structure comprises an X-shaped connecting structure and strip-shaped plates, the four end parts of the X-shaped connecting structure are connected with the strip-shaped plates, the two strip-shaped plates positioned on the same side are parallel to each other, and an exhaust channel is arranged between the two parallel strip-shaped plates; two flow guide faces are arranged on the inner side, close to the strip-shaped plate, of the X-shaped connecting structure, and the included angle between the two flow guide faces is a. The four ends of the X-shaped connecting structure are all connected with strip-shaped plates, the two strip-shaped plates located at the same end are parallel to each other, an exhaust channel is formed between the two parallel strip-shaped plates, the X-shaped connecting structure and the strip-shaped plates can keep structural integrity under the working condition of thermal runaway, high-temperature gas is guided to move towards the anti-explosion valve through the exhaust channel, and the anti-explosion valve can be used for sealing the anti-explosion valve. And the air is exhausted after exceeding the threshold value of the anti-explosion valve, so that the air exhaust channel is prevented from being blocked.
