Abstract: A battery module (100) of the present invention includes a battery cell (1) and an attachment (2). The battery cell (1) has an electro-conductive battery case (7), an electrode terminal (8) that is exposed outside the battery case (7), and electrode plates (3). The attachment (2) has a first conducting section (81), a second conducting section (82), and a resistive material (83) that is disposed between the first conducting section (81) and the second conducting section (82) and that is electrically connected to the first conducting section (81) and the second conducting section (82). The attachment (2) is attached to the electrode cell (1), and the first conducting section (81) is electrically connected to the battery case (7) and the second conducting section (82) is electrically connected to the electrode terminal (8) automatically at the time of attachment.

Abstract: A battery of the invention includes an electrode plate, leads (50, 55) that are connected to the electrode plate, external terminals (86, 87) to which the leads (50, 55) are connected, a battery case (80) which stores the electrode plate and the lead (50, 55), and to which the external terminals (86, 87) are fixed through an insulating material, and heat-dissipating bodies (60, 70) that have thermal conductivity and that come into contact with the leads (50, 55) and an inner surface of the battery case (80).

Abstract: A battery includes a stacked electrode body which is formed by stacking sequentially a first electrode plate connected to a first electrode tab, a separator, and a second electrode plate connected to a second electrode tab; an electrolyte; a battery case which seals the stacked electrode body and the electrolyte; and a guidance structure which guides the electrolyte, which moves inside the battery case due to heat generated by the stacked electrode body, to a direction inclined from a direction of gravitational force and also guides the electrolyte to the first or the second electrode tab.
