Abstract: The present application relates to the technical field of battery explosion-proof and discloses an explosion-proof sheet including a sheet body. A recess loop in a shape of an enclosed loop is formed in the sheet body, and a flip portion is formed in the sheet body within a region enclosed by the recess loop. A score in a shape of a non-enclosed loop is arranged within the recess loop, the score extends along a circumference direction of the recess loop, and a portion of the recess loop located between two ends of the score forms a connection segment configured for turning over the flip portion.
