| abstract |
The present invention relates to a stacked cell comprising: a power generation element formed of a plurality of single cell layers connected in series and stacked, each single cell layer comprising a positive electrode collector, a positive electrode active material layer, an electrolyte layer, a negative electrode active material layer, and a negative electrode collector stacked in order; and an exterior body, in which the power generation element is disposed, wherein the positive electrode collector and/or the negative electrode collector comprises a conductive resin layer, and the power generation element is further equipped with a resistance reducing layer that is next to the resin layer and on the outer surface side of the single cell layer comprising the resin layer. The present invention provides a means to increase the output performance of a stacked secondary cell using a resin collector. |
