Abstract

Una batería electroquímica que presenta un conjunto de disipación de presión que cesa de manera reversible la operación de la batería cuando la presión interna de la batería alcanza un umbral predeterminado. Si, una vez activado el conjunto de disipación de la presión, la presión interna continua aumentando a un segundo umbral, se activa un mecanismo de venteo para liberar los contenidos presurizados de la batería.
