Description
【発明の詳細な説明】
本発明は改良されたスペーサを備えた蓄電池に
関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a storage battery with an improved spacer.
スペーサに極板の耳の部分にまで延びる部分を
設け、ストラツプの端部に該部分を係止して、該
スペーサの浮き上がりを防止することが提案され
ている。 It has been proposed to provide the spacer with a portion extending to the ear portion of the electrode plate, and to lock this portion to the end of the strap to prevent the spacer from lifting up.
ところで蓄電池のシヨートの一因として陰極板

達するより早く、該部においてシヨートが発生し
寿命となるという問題点があつた。 Incidentally, one of the causes of shoots in storage batteries is that sponge lead is deposited on the cathode plate, eventually grows to the anode strap, and shoots upward.
In addition, the cathode plate located at the end of the electrode group (hereinafter referred to as the cathode side plate) is generally thinner than the other cathode plates (hereinafter referred to as the cathode center plate). If the side of is also extended,
Since there is less space on this cathode side plate for sponge lead to grow than on the cathode center plate, the sponge lead generated on the cathode side plate reaches the anode strap while the sponge lead generated on the cathode center plate reaches the anode strap. There was a problem in that shoots occurred at this part before reaching the end, and the service life came to an end.

するものである。 The present invention has been made in view of the above points, and includes a spacer in which the anode strap side is lower than the cathode strap side in a storage battery, and
This device is characterized in that a spacer lifting prevention protrusion, which is thinner than the thickness of the cathode strap, is provided at a position higher than the height of the spacer at the end of the cathode strap.

That is, Figures 1 and 2 are a front sectional view and a side sectional view of the main part, respectively, where 1 is a battery case, 2 is a battery case lid, 3 is an anode plate, 4a is a cathode center plate, and 4b is a cathode side plate. , 5 is a separator, 6 is a cathode strap, 7 is an anode strap, 8 is a spacer, 9 is an electrolyte, and 10 is a splash-proof plate. At both ends of the cathode strap 6, anti-lifting protrusions 1 having a thickness half the thickness of the cathode strap 6 are provided.
1 is provided. The spacer 8 has a step-like shape in which the cathode strap 6 side has the same height as the bottom surface of the cathode strap 6, and the anode strap 7 side has the same height as the upper side of the electrode plate surface of the cathode side plate 4b. have.

It has the following effects.

No reduction in capacity occurs.

している。b A spacer lifting prevention protrusion is provided at a position higher than the height of the spacer, and a gap is formed between the upper edge of the spacer and the spacer lifting prevention protrusion due to dimensional errors in the electrode plate, spacer, etc. The pole plate is not lifted up by the spacer. If the upper edge of the spacer is lower than the upper edge of the separator, the splash-proof plate will shift in the stacking direction of the electrode plates, causing shoots, so the height of the spacer should be higher than the height of the separator. There is a need. By the way, since the gap between the splash-proof plate and the cathode strap is relatively narrow, if the spacer lifting prevention protrusion has the same thickness as the cathode strap,
The top edge of the spacer is likely to be lower than the top edge of the separator. For this reason, in the present invention, the spacer lifting prevention protrusion is thinner than the thickness of the cathode strap and has a shape cut out at the bottom.

ことにより適用可能である。 Although only one embodiment of the present invention has been described in detail above, the present invention is also applicable to, for example, a storage battery in which separators are arranged in a zigzag pattern between electrode plates and cover the outer surface of a cathode side plate. Even against
This can be applied by lengthening the spacer lifting prevention protrusion accordingly.
