Abstract
The battery comprises a can, a cap, and a seal. The cap fits into the can to build a housing with a closed interior volume, and the seal sealing cap and can in relation to one another. A porous membrane spills the interior volume into two subcells with each subcell containing one or multiple layers of electrolyte and one or multiple layer structures. The latter comprise a conducting film at least partially coated with active material and contain one or more through-holes. The layer structure is parallel to the porous membrane and the conducting film is connected to either can or cap. This construction allows for a large area of contact between active material and electrolyte and as between electrolyte and porous membrane which result in a high performance of the battery.
