The invention relates to the power battery technology, especially to a power battery and anti-explosion device thereof, comprising an anti-explosion disc disposed in an anti-explosion bore. The surface of the anti-explosion disc is attached with an anti-explosion ring and an anti-explosion patch, the anti-explosion ring and the anti-explosion patch are at the same side of the anti-explosion disc and the anti-explosion ring and the anti-explosion patch form an annular groove. Compared with the prior art, the anti-explosion device has a simple structure, accurate explosion pressure, high intensity and it is not easy to be damaged. When the power battery is abnormal in use and the inner side has high pressure, the anti-explosion disc will explode under certain pressure to prevent explosion of the battery. It improves the safety of the power battery.
