Abstract

La presente invención proporciona una batería capaz de reducir o eliminar el deterioro de un electrodo positivo debido al calor durante la soldadura térmica de un separador, y la prevención de cortocircuitos por la sección soldada. Esta batería (10) tiene: un electrodo (40) positivo embolsado, donde en al menos una parte de la sección de extremo de un separador (60) está unido por soldadura térmica para formar una bolsa, y un electrodo (50) positivo está dispuesto dentro de la bolsa formada, y un electrodo (30) negativo que se coloca sobre el electrodo (40) positivo embolsado y es más grande que el electrodo (50) positivo. Una sección (62) soldada formada sobre el separador (60) por soldadura térmica está dispuesta, como se ve desde la dirección en capas, sobre el lado exterior del perímetro exterior del electrodo (30) negativo.
