Description

蓄电池的电导体Battery electrical conductor 技术领域Technical field
本发明涉及电池技术领域，特别涉及一种蓄电池的电导体。The present invention relates to the field of battery technologies, and in particular, to an electrical conductor of a battery.
背景技术Background technique
蓄电池的电导体通常是由边框1、极耳2、若干粗细均匀的横筋条3和竖筋条4组成，如图1，极耳2位于边框1的一侧边缘，各横筋条3与各竖筋条4之间相互交叉设置在边框1的内侧，各横筋条3之间相互平行等间距设置，各竖筋条4之间相互平行等间距设置，之后在具有横筋条3和竖筋条4的边框1一面涂抹上铅膏后即得蓄电池的极板。在工作过程中，铅膏中的电子会移动到各横筋条和各竖筋条内，再沿各竖筋条向上移动最终汇集到极耳位置，所以距离极耳较近的竖筋条和横筋条一端电流相对距离较远的一端就较大，而由横筋条和竖筋条各部分粗细均匀，所以各部分电阻基本相同(只考虑材料面积的情况下)，这样就导致距离极耳较近的竖筋条和横筋条一端电压较大，进而导致距离极耳较近部位的铅膏中活性物质利用率较高，而活性物质在工作时会释放硫酸等腐蚀性物质，容易腐蚀竖筋条和横筋条，在实际应用中，往往会出现距离极耳较近的竖筋条和横筋条已经被腐蚀断裂，而距离极耳较远的竖筋条和横筋条还完好无损，整个电导体各部分利用不均，使用寿命较短，造成资源浪费。The electrical conductor of the battery is usually composed of a frame 1, a tab 2, a plurality of thick and horizontal ribs 3 and a vertical rib 4, as shown in Fig. 1, the tab 2 is located at one side edge of the frame 1, and the transverse ribs 3 and the vertical The ribs 4 are arranged on the inner side of the frame 1 with each other, and the horizontal ribs 3 are arranged at equal intervals in parallel with each other, and the vertical ribs 4 are arranged at equal intervals with each other, and then the transverse ribs 3 and the vertical ribs 4 are provided. The side of the frame 1 is coated with a lead paste to obtain the battery plate. During the work process, the electrons in the lead paste will move into the cross ribs and the vertical ribs, and then move up along the vertical ribs and finally gather to the ear positions, so the vertical ribs and the transverse ribs are closer to the ear. The end of the strip with a relatively long distance from the current is larger, and the thickness of each part of the cross rib and the vertical rib is uniform, so the resistance of each part is basically the same (only considering the material area), so that the distance is closer to the ear The vertical ribs and the transverse ribs have a large voltage at one end, which leads to a higher utilization rate of the active material in the lead paste near the ear, and the active material releases corrosive substances such as sulfuric acid during work, and easily corrodes the vertical ribs. And transverse ribs, in practical applications, the vertical ribs and transverse ribs that are closer to the ear are often corroded and fractured, while the vertical ribs and transverse ribs far from the ear are intact, and the entire electrical conductor is Partial utilization is uneven, and the service life is short, resulting in waste of resources.
发明内容Summary of the invention
发明目的：针对现有技术中存在的问题，本发明提供一种蓄电池的电导体，能够有效平衡电导体上各部分铅膏中活性物质中的电子的利用率，有效延长电导体寿命。OBJECT OF THE INVENTION In view of the problems in the prior art, the present invention provides an electrical conductor of a battery, which can effectively balance the utilization of electrons in the active material in each portion of the lead paste on the electrical conductor, and effectively extend the life of the electrical conductor.
技术方案：本发明提供了一种蓄电池的电导体，包括边框、极耳、若干横筋条和若干竖筋条，所述极耳位于所述边框一侧边缘，各所述横筋条与各所述竖筋条相互交叉导通设置在所述边框内侧，若干所述竖筋条中至少有一条主竖筋条与所述极耳位于同一直线上，其余各竖筋条以所述主竖筋条为基线依次向两侧排开，从靠近向远离所述极耳的一端，各所述竖筋条之间的间距逐渐缩小，从靠近向远离所述主竖筋条的方向，各所述竖筋条的面积逐渐减小，两两所述竖筋条之间的间距逐渐减小，且各所述竖筋条均为尖锥状，靠近所述极耳的一端较粗；若干所述横筋条均以所述主竖筋条为端线向两侧延伸。Technical Solution: The present invention provides an electrical conductor for a battery, comprising a frame, a tab, a plurality of transverse ribs, and a plurality of vertical ribs, the tabs being located at one side edge of the frame, each of the transverse ribs and each of the The vertical ribs are disposed on the inner side of the frame, and at least one of the plurality of vertical ribs is located on the same line as the tabs, and the other vertical ribs are the main ribs Arranging for the baseline to the two sides in sequence, from the end close to the pole, the spacing between the vertical ribs is gradually reduced, from the approaching direction away from the main vertical ribs, each of the vertical The area of the ribs is gradually reduced, the spacing between the two of the vertical ribs is gradually reduced, and each of the vertical ribs is tapered, and one end of the rib is thicker; The strips extend to both sides with the main vertical ribs as end lines.
优选地，从靠近向远离所述主竖筋条的一端，各所述横筋条之间的间距逐渐缩小。Preferably, the spacing between the transverse ribs is gradually reduced from near one end away from the main vertical ribs.
优选地，从靠近向远离所述极耳的一端，各所述横筋条的面积逐渐减小。Preferably, the area of each of the transverse ribs gradually decreases from near one end away from the tab.
优选地，从靠近向远离所述极耳的一端，两两所述横筋条之间的间距逐渐减小。 Preferably, the spacing between the two transverse ribs is gradually reduced from near one end away from the tab.
优选地，各所述横筋条均为尖锥状，靠近所述主竖筋条的一端较粗。Preferably, each of the transverse ribs has a pointed shape, and one end of the main vertical rib is thicker.
有益效果：首先，本发明从靠近向远离所述极耳的一端，两两竖筋条之间的间距逐渐缩小，且从靠近向远离主竖筋条的一端，两两横筋条之间的间距逐渐缩小，这样，在电导体上涂抹铅膏后，远离极耳的一端，由各横筋条与各竖筋条组成的方块就较小，较小的方块内铅膏中活性物质中的电子能够较快地移动到各横筋条和各竖筋条上(因为方块较小，所以移动位移较小)，然后电子沿各筋条移动到极耳位置被极耳利用；而距离极耳较近的电导体一端，各横筋条与各竖筋条组成的方块就较大，较大的方块内铅膏中活性物质中的电子相对于较小方块内的电子来说，移动到各横筋条和各竖筋条上所需要的时间较长(因为方块较大，所以移动位移较大)，所以上述结构相当于平衡了距离极耳较近端和较远端电导体上活性物质中电子的利用率；Advantageous Effects: Firstly, the present invention gradually narrows the distance between the two vertical ribs from the end close to the pole, and the distance between the two ribs from the end close to the main vertical rib Gradually shrinking, so that after applying the lead paste on the electrical conductor, away from the end of the ear, the square consisting of the transverse ribs and the vertical ribs is smaller, and the electrons in the active substance in the lead paste in the smaller square can Move faster to each of the horizontal ribs and the vertical ribs (because the square is smaller, so the movement displacement is smaller), then the electrons move along the ribs to the tab position and are used by the tabs; and closer to the tabs At one end of the electrical conductor, the squares of the transverse ribs and the vertical ribs are larger. The electrons in the active material in the larger paste in the larger square move to the transverse ribs and the electrons in the smaller squares. The time required for the vertical ribs is longer (because the squares are larger, so the displacement is larger), so the above structure is equivalent to balancing the utilization of electrons in the active material at the proximal end and the far-end electrical conductor. ;
其次，本发明从靠近向远离主竖筋条的方向，各竖筋条的面积逐渐减小；从靠近向远离极耳的一端，各横筋条的面积逐渐减小；面积较大的竖筋条和横筋条电阻较小(只考虑材料面积的情况下)，在电流相等的情况下，面积较大的竖筋条和横筋条上的电压相对较小，这样就能够相对降低靠近极耳位置的铅膏中活性物质的利用率，提升远离极耳位置的铅膏中活性物质的利用率，从而达到均衡利用整个电导体上各部分竖筋条和横筋条的目的，提升整个电导体的使用寿命，节约资源能源；Secondly, according to the invention, the area of each vertical rib is gradually reduced from the direction away from the main vertical rib; from the end close to the distal end, the area of each transverse rib is gradually reduced; the vertical rib having a larger area And the resistance of the transverse ribs is small (only considering the material area), in the case of equal current, the voltage on the vertical ribs and the ribs of the larger area is relatively small, so that the position near the tabs can be relatively reduced. The utilization rate of the active substance in the lead paste improves the utilization rate of the active material in the lead paste far away from the position of the ear, thereby achieving the purpose of balancing the use of the vertical ribs and the transverse ribs of the entire electrical conductor, thereby improving the service life of the entire electrical conductor. , saving resources and energy;
再次，本发明从靠近向远离主竖筋条的方向，两两所述竖筋条之间的间距逐渐减小；从靠近向远离极耳的一端，两两所述横筋条之间的间距逐渐减小；这样，在电导体上涂抹铅膏后，远离极耳的一端，由各横筋条与各竖筋条组成的方块就进一步减小，小方块内铅膏中活性物质中的电子能够较快地移动到各横筋条和各竖筋条上，然后电子沿各筋条移动到极耳位置被极耳利用；而距离极耳较近的电导体一端，各横筋条与各竖筋条组成的方块就进一步增大，所以距离极耳较近的电导体一端，铅膏中活性物质中的电子移动到各横筋条和各竖筋条上所需要的时间相对于距离极耳较远的电导体一端就更长，所以上述结构相当于进一步平衡了距离极耳较近端和较远端电导体上活性物质中电子的利用率；Again, the present invention gradually reduces the spacing between the two of the vertical ribs in a direction away from the main vertical rib; from the end closer to the distal end, the spacing between the two ribs gradually Decreasing; thus, after applying the lead paste on the electrical conductor, away from the end of the ear, the square consisting of the transverse ribs and the vertical ribs is further reduced, and the electrons in the active substance in the lead paste in the small square can be compared. Move quickly to each of the horizontal ribs and the vertical ribs, and then the electrons are moved along the ribs to the tabs to be used by the tabs; and the ends of the electrical conductors that are closer to the tabs, the transverse ribs and the vertical ribs The squares are further enlarged, so that the end of the electrical conductor closer to the ear, the time required for the electrons in the active material in the paste to move to the transverse ribs and the vertical ribs relative to the conductance farther from the ear The end of the body is longer, so the above structure is equivalent to further balancing the utilization of electrons in the active material on the nearer end and the farther electrical conductor;
最后，各竖筋条均为尖锥状，靠近极耳的一端较粗；各横筋条均为尖锥状，靠近主竖筋条的一端较粗，电子沿各横筋条和竖筋条移动汇集到靠近极耳的位置时，由于靠近极耳的竖筋条一端较粗、靠近主竖筋条的横筋条一端较粗，相对于较细的远离极耳的竖筋条一端、较细的远离主竖筋条的横筋条一端，较粗端的电阻较小(只考虑材料面积的情况下)，在电流相等的情况下，较粗端的电压相对较小，这样就能够相对降低靠近极耳位置的铅膏中活性物质的利用率，提升远离极耳位置的铅膏中活性物质的利用率，从而达到均衡利用 整个电导体上各部分竖筋条和横筋条的目的，提升整个电导体的使用寿命，节约资源能源。Finally, each of the vertical ribs is tapered, and the end near the ear is thicker; each of the transverse ribs is tapered, the end near the main vertical rib is thicker, and the electrons move along the transverse ribs and the vertical ribs. When approaching the position of the tab, the end of the vertical rib close to the tab is thicker, and the end of the cross rib near the main rib is thicker, which is thinner than the end of the thin rib that is far from the tab. The end of the transverse rib of the main vertical rib has a smaller resistance at the thicker end (only considering the material area). In the case of equal current, the voltage at the thicker end is relatively small, so that the position near the tab can be relatively reduced. The utilization rate of the active substance in the lead paste improves the utilization rate of the active substance in the lead paste far from the position of the ear, thereby achieving balanced use The purpose of the vertical ribs and the transverse ribs on the entire electrical conductor is to enhance the service life of the entire electrical conductor and save resources and energy.
综上，相对于现有技术中的电导体来说，本发明中的电导体上各部分活性物质中电子的利用率相对均衡，有效避免距离极耳较近端的横筋条和竖筋条由于这部分的活性物质利用率较大而被腐蚀断裂，有效提升电导体的寿命。In summary, compared with the electrical conductors in the prior art, the utilization ratio of electrons in each part of the active material in the electric conductor of the present invention is relatively balanced, and the transverse ribs and the vertical ribs which are closer to the proximal end of the ear are effectively avoided. This part of the active material utilization is large and is corroded and fractured, effectively improving the life of the electrical conductor.
