The invention discloses an explosion-proof structure of a miniature lithium ion battery, and aims to provide the explosion-proof structure of the miniature lithium ion battery, which is simple in structure and good in explosion-proof effect. The structure comprises a shell, a rubber ring and a cover body; an opening is formed in the upper end of the shell, the cover body seals the opening throughthe rubber ring; after the shell is sealed, an inwards-bent pressing part bent inwards is arranged at the opening, the rubber ring is connected to the outer edge of the cover body in a sleeving mode,the upper end of the inner folding pressing part is pressed on the outer side of the rubber ring and is buckled on the outer edge of the cover body through the rubber ring; the inwards-folded pressingpart is asymmetric in the full-sealed perimeter, wherein the wrapping length of the shell at one end is larger than that of the shell at the other end. The explosion-proof structure is applied to thetechnical field of explosio
