Abstract
(EN)
The purpose of the present invention is to make it possible to prevent the leakage of an electrolyte and reduce pressure loss. According to the present invention, air batteries have an electrolyte layer holding an electrolyte between a positive electrode material and a negative electrode material and each have an air flow path formed therein for allowing air to flow to and contact the positive electrode material. In the air batteries, a leakage preventing material (S) is provided that absorbs the electrolyte leaking from the electrolyte layer and swells to fill an air flow path (20).

L'objectif de la présente invention est de permettre d'éviter la fuite d'un électrolyte et de réduire la perte de pression. Selon la présente invention, des batteries à air ont une couche d'électrolyte qui maintient un électrolyte entre un matériau d'électrode positive et un matériau d'électrode négative, et chacune ayant un trajet d'écoulement d'air formé dans celle-ci afin de permettre à l'air de circuler et d'être en contact avec le matériau d'électrode positive. Dans les batteries à air, un matériau de prévention de fuite (S) est disposé et absorbe l'électrolyte qui fuit à partir de la couche d'électrolyte, et gonfle pour remplir un trajet d'écoulement d'air (20).
