摘要： On the opposite end walls (8) of a flat, primatic battery case (2) of a battery module (1) where electrode terminals (12) are attached, protruding components (26) are formed such as to protrude further than the electrode terminals. Terminal holes (10) are formed in the end walls in which the electrode terminals are fitted, and the thickness of the end walls of the integral battery case in the vicinity of the terminal holes is not the same on both sides of each of the terminal holes. Also, each of the electrode terminals has a mounting structure comprising a disk-shaped seat (12a) from one surface of which the electrode terminal protrudes, a connecting protrusion (24) protruding from an opposite surface of the electrode terminal, an annular groove (40a) formed around and coaxial with said connecting protrusion, and an annular protrusion (40) around and coaxial with said annular groove. The engagement tabs (38) are formed extending radially and centred around the connecting protrusion. The engagement grooves (37) and the circular recess are connected and coplanar. The engagement tabs (38) and the annular protrusion (40) are connected and coplanar.

摘要： A battery (1) which has undergone initial charging and discharging is placed inside a sealed vessel (3), which is evacuated by a vacuum pump (9). After this evacuated state has been maintained for a while, the density of hydrogen gas within the sealed vessel (3) is measured by a hydrogen density sensor (11), based on which the presence or absence of a gas escape from the battery is determined. The battery may be heated instead of subjecting it to charging and discharging.

摘要： The present invention discloses a method for manufacturing an electrode for a battery by filling an active material into a three-dimensional porous metal substrate sheet and cutting said sheet to a certain size, comprising the steps of: pressing the portion to be cut and the periphery thereof in the substrate sheet; coating the portion to be cut and the periphery thereof in the substrate sheet with a resin; and/or impregnating the portion to be cut and the periphery thereof in the substrate sheet with a liquid containing a resin component, in addition to the steps of: filling an active material into the substrate sheet; and cutting the substrate sheet at the portion to be cut. This method prevents the occurrence of burrs and cuttings while the sheet is being cut and the coming off of the active material, thereby suppressing internal short circuit of the battery. As a result, a battery hardly suffering from a deterioration in preservation performance and charge-discharge cycle life can be obtained.

摘要： A battery module includes a plurality of cells (6) accommodating an electrode plate group (5) and an electrolyte, and a single integrated battery case (2) for accommodating the plurality of cells (6), the cells may be connected through lead portions protruding sideways on the lateral side of the cells. The ratio of the component resistance including the connecting resistance between the cells to the reactive resistance of the electrode plate group and the electrolyte in each cell, is set in the range of 1:99 - 40:60 at a temperature of 25°C. Thereby, the internal resistance per cell is reduced, and higher power output and improved service life characteristics are achieved.
