A method of fabricating a battery explosion prevention safety device includes the steps of electroforming a first metal floor layer on a conductive substrate, coating the first metal layer with a photoresist layer, overlaying the photoresist layer with a photomask having windows that define the shape of a safety valve, irradiating the photoresist layer with ultraviolet light, developing the photoresist layer, and removing unexposed portions of the photoresist layer to expose the first metal layer at those portions, electroforming a second metal layer on the first metal layer, removing exposed portions of the photoresist layer, and separating the conductive substrate from the first metal layer. This method is used to fabricate a plurality of connected explosion prevention safety devices, which can then be readily detached one at a time when needed.
