Abstract

PURPOSE:To retard the deterioration in battery performance and make it possible to be used in any position by coating a vent hole with water repellent and acid resistant material to prevent the movement of electrolyte. CONSTITUTION:The surroundings of a vent hole 4 installed in the upper part of a partition 2 which partitions a container in plural cells is coated with water repellent and acid resistant polyester resin 5. Even when a battery falls down and free-electrolyte flows, the resin 5 repels the electrolyte and the entry of the electrolyte into the hole 4 is obstructed by a bank effect of the resin 5 to prevent the movement of electrolyte between cells. Thereby, the deterioration in battery performance is retarded and the battery can be used in any position.

った。2. Problems to be solved by the vane invention Therefore, in order to reduce costs, a system was devised in which the exhaust holes were made common to each cell and a collective exhaust safety valve was provided. However, with this structure, when the battery is turned over so that the isolation wall is horizontal, free electrolyte may flow between cells through the ventilation holes in the isolation wall, resulting in non-uniformity of the electrolyte. There was a problem that performance variations occurred due to

することができる。Effect 3=-: In this way, when a water-repellent substance is applied to the vent holes, when a sealed lead-acid battery with a low amount of free electrolyte is overturned so that the separating wall is horizontal, the electrolyte will leak between the cells. Movement can be prevented, and deterioration in battery performance due to liquid junctions and changes in liquid volume can be suppressed.

ことができる。EXAMPLES The details of this invention will be explained below using examples. In Fig. 1, 1 is a battery case, and 2 is a separation wall that partitions the battery case into a plurality of cells.A hole with a diameter of 3mm is bored in a part of each separation wall as a ventilation hole 4. A water-repellent polyester resin 6 is applied around it. FIG. 1 shows a part of the battery case with the battery turned over so that the separating wall 2 is horizontal. The resin 5 is applied uniformly around the ventilation hole 4 as shown in the figure, and also in the second area.
As shown in the figure, it can also be applied in a high heap like a layer. If the battery is configured as shown in Figure 2, even if free electrolyte flows out when the battery is tipped over, the coating material will repel the electrolyte and the effect of the raised layer will prevent the holes from leaking.
It is possible to prevent the electrolyte from moving between cells by preventing the electrolyte from entering the cell.
