Battery module

A battery module comprising:

• a cell that has a cathode resin current collector, a cathode active material layer, a separator, an anode active material layer, and an anode resin current collector,
• wherein the cell comprises a frame member that seals the cathode active material layer, the separator, and the anode active material layer,
• wherein the cathode resin current collector is placed on a first surface of the cell,
• wherein the anode resin current collector is placed on a second surface of the cell,
• a first assembled battery in which a predetermined number of adjacent pairs of the cells are stacked in series such that the first surface and the second surface of the adjacent pair of the cell are adjacent to each other, or a first assembled battery in which a predetermined number of cells, each of which has a cathode layer provided on one surface of a resin current collector and an anode layer provided on the other surface of the resin current collector, are stacked via an electrolyte layer;
• in a case when the inductance of the cell is Ia,
• the inductance of a wound-type cell consisting of a wound electrode group having a cathode plate that comprises a cathode metal current collector and a cathode mixture layer disposed on both sides of the cathode metal current collector, an anode plate that comprises an anode metal current collector and an anode mixture layer disposed on both sides of the anode metal current collector, and a separator that is disposed between the cathode plate and the anode plate, is Ib,
• the inductance of the first assembled battery is Ic,
• the inductance of a first wound-type cell module formed by connecting the predetermined number of the wound-type cells in series is Id,
• wherein Ic/Ia<Id/Ib.
