1. A lithium ion battery comprising a cell formed by sequentially stacking a positive current collector, a positive active material layer, a separator, a negative active material layer, and a negative current collector,
the lithium ion battery comprising a frame member disposed between the positive current collector and the negative current collector to seal the positive active material layer, the separator, and the negative active material layer,
the frame member having, disposed therein, an electronic component which detects an internal condition of the cell.
