Interface between jelly roll area of a battery cell and cell can

A cylindrical battery cell, comprising:

• a cell can;
• a jelly roll area of anode electrode foils, separator foils and cathode electrode foils arranged in a middle section of the cell can, wherein at least one of the electrode foils extend out of the jelly roll area into an electrolyte area;
• and
• a plurality of connection taps being thermally and electrically connected to a first end of the cell can,
• wherein a first subset of the at least one of the electrode foils are in direct contact with a first of the plurality of connection taps, and
• wherein a second subset of the at least one of the electrode foils are in direct contact with a second of the plurality of connection taps.

A cylindrical battery cell, comprising:

• a cell can;
• and
• a jelly roll area of anode electrode foils, separator foils and cathode electrode foils arranged in a middle section of the cell can, wherein at least one of the electrode foils comprise parts that extend out of the jelly roll area into an electrolyte area,
• wherein the extended parts of the at least one of the electrode foils are bent and stacked so as to function as a foil-integrated connection tap that is thermally and electrically connected to a first end of the cell can.
