Abstract

Official abstract text for this publication.

A current collector foil for a liquid cell includes: one first electrode foil having a pinhole; a first intervening layer; another first electrode foil having a pinhole; a second intervening layer; and a second electrode foil, the one first electrode foil, the first intervening layer, the other first electrode foil, the second intervening layer, and the second electrode foil being stacked in this order. Either the one first electrode foil and the other first electrode foil or the second electrode foil is a positive electrode foil, and either the one first electrode foil and the other first electrode foil or the second electrode foil, whichever is not the positive electrode foil, is a negative electrode foil.

First claim

Opening claim text (preview).

What is claimed is: 1 . A current collector foil for a liquid cell, the current collector foil comprising: one first electrode foil having a pinhole; a first intervening layer; another first electrode foil having a pinhole; a second intervening layer; and a second electrode foil, the one first electrode foil, the first intervening layer, the other first electrode foil, the second intervening layer, and the second electrode foil being stacked in this order, wherein either the one first electrode foil and the other first electrode foil or the second electrode foil is a positive electrode foil, and either the one first electrode foil and the other first electrode foil or the second electrode foil, whichever is not the positive electrode foil, is a negative electrode foil. 2 . A liquid cell comprising: the current collector foil according to claim 1 ; a positive electrode active material layer; a negative electrode active material layer; a separator; and an electrolyte solution.
