Abstract
Se proporciona una válvula de seguridad que se puede fabricar fácilmente sin necesidad de instalaciones y técnicas de fabricación de alta precisión; una caja de la batería provista de la válvula de seguridad; y un método para formar la válvula de seguridad. Una válvula de seguridad que tiene un espesor parcialmente reducido en una caja de la batería comprende: una sección plana; y una ranura que se forma en el borde periférico de la sección plana y que está rebajada hacia el interior de la caja de la batería. Cuando la presión interna dentro de la caja de la batería alcanza o supera una presión predeterminada de prevención de explosiones, la forma cóncava de la ranura se invierte de modo que la ranura sobresalga hacia el exterior de la caja de la batería y se forme una grieta, lo que hace que la ranura se abra.
