According to the pressure relief device for the lithium ion storage battery power supply, heat is conducted to the cooling piece when gas passes through the cooling piece, cooling of the gas is achieved, the surface area of the cooling piece is increased through the holes of the cooling piece, the contact area of the gas and the cooling piece is increased, and the pressure relief effect is improved. Therefore, more heat in the gas can be conducted to the cooling part, the temperature of the gas is sharply reduced, the gas passing through the pressure relief channel is greatly cooled, combustion of the waterproof ventilation valve caused by contact between the high-temperature gas and the waterproof ventilation valve can be avoided, and the safety of the lithium ion storage battery power supply is greatly improved. And for flames generated by the power supply of the lithium ion storage battery due to thermal runaway, the cooling piece can also realize good cooling, so that the flames are extinguished. 本实用新型提供一
