Therefore, energy storage technology is a key technology that needs to be solved for solar and wind power generation to become the main energy source, and it is a key link that cannot be bypassed in the development of new energy sources. Industry insiders believe that the future of energy storage batteries should be in the wind power and photovoltaic industries, especially the wind power industry that has already been deployed in large numbers. Due to the instability of wind resources, although the wind and photovoltaic industries have developed rapidly in recent years, they have been troubled by grid connection.

如图1所示,一种高效储能电池,其包括外壳体9、极板组7、附加负极板6、附加隔板5、极柱8和上隔板3。其中,外壳体9为聚丙烯壳体,其内设有空腔,顶部设有开口和盖板,外壁面下部设置有用于卡接的凸起10,所述空腔内放置有电解液。凸起10可与卡槽配合,实现卡接,从而将外壳体9安装在工作位置上,为了便于卡合进卡槽,所述凸起10上设置有下滑坡面。As shown in FIG. 1 , a high-efficiency energy storage battery includes an outer casing 9 , a pole plate group 7 , an additional negative plate 6 , an additional separator 5 , a pole 8 and an upper separator 3 . Wherein, the outer shell 9 is a polypropylene shell with a cavity inside, an opening and a cover plate on the top, and a protrusion 10 for clamping on the lower part of the outer wall. Electrolyte is placed in the cavity. The protrusion 10 can cooperate with the card slot to realize card connection, so that the outer shell 9 is installed in the working position. In order to facilitate the card slot, the protrusion 10 is provided with a downslope.

如图1所示,极板组7置于所述外壳体9的空腔内。该极板组7由多个隔板、多个涂有活性物质的正极板、多个涂有活性物质的负极板组成,且正极板的数量与负极板的数量相等。正极板和负极板采用了低锑合金(含锑量2%~3%)或无锑合金栅架。低锑合金栅架是采用低锑多元合金,其含锑量在1%~3%,除含锑量减少外,还增加了铜、砷、锡、硒等合金元素,以改善因含锑量减少而造成栅架铸造和机械强度方面的不足。无锑合金栅架采用铅钙合金或铅钙锡合金,含钙量在0.08%~0.1%,含锡量在0.3%~0.9%。以铅钙合金作为极板栅架,由于完全消除了锑的副作用,自行放电少,耐过充能力强,出气量和耗水量也非常小。电池在使用过程中水消耗主要有两个途径,一个是水的蒸发(约占10%左右),另一个是充电过程中水的电解(约占90%左右),尤其在过充电情况下水的电解更为严重。由于采用了低锑多元合金或铅钙合金作为栅架材料,使其耐过充电能力增强,从而使充电末期水的电解量大大减少,因而在整个使用过程中无需加水,可以实现免维护。As shown in FIG. 1 , the electrode plate group 7 is placed in the cavity of the outer casing 9 . The plate group 7 is composed of a plurality of separators, a plurality of positive plates coated with active materials, and a plurality of negative plates coated with active materials, and the number of positive plates is equal to the number of negative plates. The positive plate and the negative plate are made of low antimony alloy (2%-3% antimony content) or non-antimony alloy grid frame. The low-antimony alloy grid frame is made of low-antimony multi-element alloy, and its antimony content is 1% to 3%. The reduction results in deficiencies in grid casting and mechanical strength. The antimony-free alloy grid is made of lead-calcium alloy or lead-calcium-tin alloy, with a calcium content of 0.08% to 0.1% and a tin content of 0.3% to 0.9%. The lead-calcium alloy is used as the grid frame, because the side effects of antimony are completely eliminated, the self-discharge is less, the overcharge resistance is strong, and the gas output and water consumption are also very small. There are two main ways for the battery to consume water during use, one is the evaporation of water (accounting for about 10%), and the other is the electrolysis of water during charging (accounting for about 90%), especially in the case of overcharging. Electrolysis is more serious. Due to the use of low-antimony multi-element alloy or lead-calcium alloy as the grid material, its ability to withstand overcharge is enhanced, so that the amount of electrolysis of water at the end of charging is greatly reduced, so there is no need to add water during the entire use process, and maintenance-free can be achieved.

正极板上的活性物质为褐色的二氧化铅,这层二氧化铅由结合氧化的铅细粒构成,在这些细粒之间能够自由地通过电解液。铅磨成细粒的原因是可以增大其与电解液的接触面积,这样可以增加反应面积,从而减小内阻。负极板上的活性物质为深灰色的海绵状纯铅。所述正极板和负极板交错设置,相邻的正极板和负极板之间通过隔板隔开。所述隔板优选为木质隔板、橡胶隔板、微孔橡胶隔板、微孔塑料隔板、玻璃隔板中的任一种。在本实施例中,隔板选用微孔聚氯乙烯隔板。各个正极板、负极板和隔板在所述外壳体9的空腔内平行排列。The active material on the positive plate is brown lead dioxide, which is composed of bound oxidized lead fine particles between which the electrolyte can pass freely. The reason why the lead is ground into fine particles is to increase its contact area with the electrolyte, which can increase the reaction area and thereby reduce the internal resistance. The active material on the negative plate is dark gray spongy pure lead. The positive electrode plates and negative electrode plates are arranged alternately, and adjacent positive electrode plates and negative electrode plates are separated by separators. The partition is preferably any one of a wooden partition, a rubber partition, a microporous rubber partition, a microporous plastic partition, and a glass partition. In this embodiment, the separator is a microporous polyvinyl chloride separator. Each positive plate, negative plate and separator are arranged in parallel in the cavity of the outer case 9 .

附加负极板6置于所述外壳体9的空腔内,位于所述极板组7的一侧,并靠近所述外壳体9的空腔内壁。附加隔板5置于所述外壳体9的空腔内,位于所述附加负极板6和所述外壳体9的空腔内壁之间。增加一片附加负极板6,从而使每片正极板都处于两片负极板之间,使正极板两侧放电均匀,避免因放电不均匀造成极板拱曲。The additional negative plate 6 is placed in the cavity of the outer casing 9 , on one side of the electrode plate group 7 , and close to the inner wall of the cavity of the outer casing 9 . The additional separator 5 is placed in the cavity of the outer shell 9 , between the additional negative plate 6 and the inner wall of the cavity of the outer shell 9 . An additional negative plate 6 is added, so that each positive plate is between two negative plates, so that the discharge on both sides of the positive plate is uniform, and avoiding the bowing of the plates due to uneven discharge.

极柱8为两个,其中,一极柱8从所述外壳体9的盖板穿过后与所述极板组7中的正极板相连,另一极柱8从所述外壳体9的盖板穿过后与该极板组7中的负极板和附加负极板6相连。There are two poles 8, wherein one pole 8 is connected to the positive plate in the plate group 7 after passing through the cover plate of the outer casing 9, and the other pole 8 passes through the cover of the outer casing 9. After the plate passes through, it is connected with the negative electrode plate in the electrode plate group 7 and the additional negative electrode plate 6 .

上隔板3置于所述外壳体9的空腔内,位于所述极板组7的顶部与所述外壳体9中盖板内侧之间。优选地,如图1所示,所述极板组7的顶部和所述上隔板3之间通过连接板4相连。The upper separator 3 is placed in the cavity of the outer casing 9 , between the top of the electrode plate group 7 and the inside of the cover plate in the outer casing 9 . Preferably, as shown in FIG. 1 , the top of the electrode plate group 7 is connected to the upper separator 3 through a connecting plate 4 .

如图1所示,优选地,所述外壳体9的侧壁上开设有与内部空腔相连通的排烟孔2,如此一来,不但能保存电池中的酸气,并能预防火花或火焰引起的爆炸,还能保持其顶部干燥,因而降低了极柱8被腐蚀的可能性。As shown in Figure 1, preferably, the side wall of the outer casing 9 is provided with a smoke exhaust hole 2 communicating with the inner cavity, so that not only the acid gas in the battery can be preserved, but also sparks or sparks can be prevented. The explosion caused by the flame also keeps the top dry, thus reducing the possibility of the pole 8 being corroded.

进一步优选地,所述外壳体9中的盖板上设置有伸入到该外壳体9内部空腔的密度计1,以便于监测外壳体9中电解液的浓度。Further preferably, a density meter 1 protruding into the inner cavity of the outer casing 9 is provided on the cover plate of the outer casing 9 so as to monitor the concentration of the electrolyte in the outer casing 9 .

上述高效储能电池,其具有下述优点:The above-mentioned high-efficiency energy storage battery has the following advantages:

1)耐过充电能力增强,从而使充电末期水的电解量大大减少,因此使用中不需加注蒸馏水或很少加注蒸馏水;1) The ability to withstand overcharging is enhanced, so that the amount of electrolysis of water at the end of charging is greatly reduced, so there is no need to add distilled water or rarely add distilled water during use;
