【従来の技術】鉛蓄電池などのように、電解液に水溶液
を用いる電池では、水素ガスや酸素ガスが特に充電の終
期に多量に発生する。これらのガスは電池の排気孔から
電池外部に放出させているが、水素ガス濃度が４％以上
では急激な燃焼反応が生じるため、排気孔の近辺に火点

工夫がされている。2. Description of the Related Art In a battery such as a lead storage battery using an aqueous solution as an electrolyte, a large amount of hydrogen gas or oxygen gas is generated particularly at the end of charging. These gases are discharged outside the battery through the exhaust hole of the battery. However, if the hydrogen gas concentration is 4% or more, a rapid combustion reaction occurs. Since the battery may be damaged, an explosion-proof filter is attached to the exhaust hole, or a structure of explosion-proof explosion-proof is adopted to prevent ignition inside the battery.

は、安価ではあるが、防爆性能が前者に比べて劣る。As shown in FIG. 1, a battery having a liquid port plug in each cell has an explosion-proof liquid port plug attached to the liquid port of each cell and a shield for preventing the electrolyte from splashing inside the liquid port plug. In some cases, an explosion-proof liquid spigot with a maze structure, which is provided with a plate, is not explosion-proof, but the explosion-proof liquid spigot is more expensive than a normal liquid spigot and expensive as a battery. It becomes something. On the other hand, a battery provided with a normal type liquid stopper is inexpensive, but inferior in explosion-proof performance to the former.

In the battery of this structure, a space for connecting the cells is provided between the upper lid and the lid, and one filter having an explosion-proof function is contained in the exhaust hole. In this battery, it is necessary to join the upper lid and the lid after the injection in the manufacturing process, and the number of manufacturing processes is increased, so that the battery becomes expensive.

点からできるだけ少ない方がよい。FIG. 4 is a perspective view of the back of the lid according to an embodiment of the present invention. The through hole between cells on the back of the lid can be easily formed by setting up a pin at the time of molding. The hole formed in the side wall surface is kept airtight by fitting a sealing plug, and the sealing plugs of the five cells are kept airtight by packing. With this lid, the cells are connected via the inter-cell through hole, and the gas generated inside the battery can move freely to all the cells. Therefore, by attaching an explosion-proof liquid port plug with enhanced explosion-proof performance to one of these cells and attaching a sealing plug to the other 5 cells, the generated gas is exhausted only from the cells of the explosion-proof liquid port plug. Batteries with excellent explosion-proof performance. The number of explosion-proof liquid stoppers to be attached to the battery may be determined in consideration of the explosion-proof characteristics of the explosion-proof liquid stopper, but it is preferable that the explosion-proof liquid stopper be as small as possible in terms of battery cost.
