BATTERY SYSTEM, ELECTRIC VEHICLE PROVIDED WITH BATTERY SYSTEM, AND POWER STORAGE DEVICE

摘要

In order to reduce weight while reducing component cost and to hold cells while compressing the cells with a high pressure, this battery system is provided with: a cell laminate (2) obtained by laminating a plurality of rectangular cells (1); and binding materials (3) for binding the cell laminate (2) in the direction in which the cells (1) are laminated, and fixing each of the cells (1) in a compressed state. The binding materials (3) are flexible, looped-shaped string materials (30).
