Abstract
Description
【発明の詳細な説明】 産業上の利用分野 本発明は蓄電池の電解液攪拌に関するものである。[Detailed description of the invention] Industrial applications The present invention relates to electrolyte stirring for storage batteries.
従来技術とその問題点
蓄電池を浅い充放電で使用するか小さい電流で充電する
ときは、電解液の拡散が悪く、このため蓄電池の上部電
解液と下部電解液との濃度が異なるようになる。即ち上
部電解液比重は低くなり、下部電解液比重は高くなり、
こうして電解液比重が不均一となるので、蓄電池は容量
面及び寿命面において悪影響を受ける。Prior art and its problems When a storage battery is used in a shallow charging/discharging process or is charged with a small current, the diffusion of the electrolyte is poor, which causes the concentrations of the upper and lower electrolytes of the storage battery to be different. In other words, the upper electrolyte specific gravity becomes lower, the lower electrolyte specific gravity becomes higher,
Since the specific gravity of the electrolyte becomes non-uniform in this way, the storage battery is adversely affected in terms of capacity and life.
この悪影響解消のため通常は充電々流が大きくなる均等
充電を適宜実施して極板からガスを発生させて電解液攪

ックアップ電源として使用するものでは、充電々流を大
きくすることができなくなってきており、電解液を十分
に攪拌することが困難となっている。In order to eliminate this negative effect, normally uniform charging is carried out as needed to increase the charging current, and gas is generated from the electrode plates to stir the electrolyte, but in recent years, due to the demand for downsizing of charging equipment, When used in combination with a solar cell as a backup power source for the solar cell, it has become impossible to increase the charging current, and it has become difficult to sufficiently stir the electrolyte.
発明の目的
本発明は無動力の電解液攪拌機能を有する長寿命な蓄電
池を提供することを目的とする。OBJECTS OF THE INVENTION It is an object of the present invention to provide a long-life storage battery having a non-powered electrolyte stirring function.
発明の構成
本発明は上記の目的を達成すべく、蓄電池外部に容積の
一定なタンクを備えて、該タンクと連通した容積変動す
る膨張収縮の自在な柔軟体を電池の電解液内に備えるも
のである。Structure of the Invention In order to achieve the above object, the present invention includes a tank having a constant volume outside the storage battery, and a flexible body communicating with the tank that can expand and contract and whose volume fluctuates within the electrolyte of the battery. It is.
又容積の一定なタンクは、電池室外の屋外に配置するも
のである。Also, a tank with a constant volume is placed outdoors outside the battery room.
実施例
以下、本発明をその一実施例を示す図面により説明する
。EXAMPLE Hereinafter, the present invention will be explained with reference to drawings showing one example thereof.
第1図は本発明の蓄電池の概略図である。FIG. 1 is a schematic diagram of the storage battery of the present invention.

って、電池電解液面が上昇、降下をおこし、電解液を攪
拌させる。1 is a storage battery, 2 is a flexible body that expands and contracts within the electrolyte of the storage battery, and 3 is a communication pipe that communicates with an external tank 4 that does not change in volume outside the storage battery, and inside these,
Air or gaseous gas is enclosed. Since the external tank does not undergo a volume change, an increase in temperature will cause the gas pressure in the external tank to increase. At this time, since the flexible bodies are connected by the communication pipe, the flexible bodies expand due to changes in gas pressure. Furthermore, when the temperature drops, the flexible body also contracts due to the change in gas pressure as the gas pressure in the external tank decreases. In this way, the expansion and contraction of the flexible body causes the level of the battery electrolyte to rise and fall, stirring the electrolyte.
こ−において、外部タンクを屋外に配置することによっ
て、気温の変化が大きくなり、ガス圧の変動が大きくな
りより効率的に電解液を攪拌することができる。In this case, by arranging the external tank outdoors, changes in temperature and gas pressure are increased, and the electrolyte can be stirred more efficiently.
本発明による蓄電池と従来の攪拌機能を有しない蓄電池
の寿命性能を比較した結果、本発明による蓄電池は、従
来蓄電池よりも2倍以上長寿命であった。As a result of comparing the life performance of the storage battery according to the present invention and the conventional storage battery without a stirring function, the life of the storage battery according to the present invention was more than twice as long as that of the conventional storage battery.
又、電池外部のタンクについて複数個の単電池に接続す
ることも可能である。It is also possible to connect a plurality of single cells to a tank outside the battery.
発明の効果
本発明は無動力で蓄電池の電解液を攪拌することかもき
、しかも長寿命な蓄電池となり、その工業的価値は大で
ある。Effects of the Invention The present invention can stir the electrolyte of a storage battery without power, and also provides a long-life storage battery, which has great industrial value.
